Comet 2016 BA-14 PANSTARRS Report

Last night, several SBAS members gathered at the Worley Observatory to observe the close-passing comet, C/2016 BA-14 PANSTARRS. Many astronomers, amateur and professional have been anxious about how bright C/2016 BA-14 will get. Estimates kept this comet at around magnitude +15 up until the last day or two from what I have read. Last night was a good first opportunity to photograph the comet despite a broadly encroaching 98 percent illuminated moon. The comet has been moving awfully fast through Cancer and will be in Ursa Major within days.

Of course, I am a visual observer, so in my case, anything dimmer than magnitude +13 under moonlit skies is out of bounds. I went to hunt for the comet anyway. My gamble paid off and I am three comets away from finishing the Silver Level of the Astronomical League’s Comet Observing Program.

Armed with Skysafari and my new red-light-friendly iPhone case, my XT8, and a dew shield to help cut out stray moonlight entering my scope’s tube, I starhopped from the head of Leo over into Cancer near Xi and Omicron Cancri where BA-14 was zooming through. I started with the 35mm Astro Tech and jumped down to 70x with my 17mm Plossl, but that still did not yield any results. Initial attempts at 150x in my 8mm TMB revealed nothing, but as the sky grew darker, I convinced myself something was there. A fellow club member brought over his new Meade 6.5mm 60HD which made my efforts a little less arduous. Something was there.

It appeared as a smudge at first, but with additional dark adaptation and cupped hands over the eyepiece to block out the moonlight, the smudge became more spindle shaped. The smudge, to me, resembled a magnitude +13 edge-on elliptical galaxy. To verify that it was the comet and not my imagination, I had to observe movement across the field. Luckily, BA-14 was moving in matters of minutes.

I had the right field according to Skysafari and BA-14 was headed toward a dim star, TYC-1404-1261-1. I sketched this observation at 9pm. At 9:03, the comet had moved more northward from TYC-1404-1261-1, half-way between that star and SAO-98369. Same elliptical shape. Same brightness. Averted vision and scope nudges helped, but there were moments of direct observation where the spindle shape seemed more apparent. I sketched this observation, but continued to follow its movement some more because I still doubted what I had seen.


9:03pm observation


When BA-14 passed SAO-98369, it seemed to get slightly brighter. Another club member had a look through my scope and confirmed that “something” was indeed there, so it wasn’t just my imagination. No core or condensation. No tail.

In terms of magnitude, I am convinced BA-14 was between +11 and +13 under the impression that +13 was nowhere near possible to observe under moonlit skies and my experience with observing +11 and +12 galaxies under home skies. Why it appeared spindle shaped still perplexes me because I logged a second set of observations when I arrived home.

BA-14 had moved closer to zenith by the time I arrived home and this particular location offered the added benefit of shadows cast by trees. I set up the XT8 under a shadow for the sake of better dark adaptation and protection from moonlight, looked up BA-14 in Skysafari again, and starhopped my way there. As before, the initial observation was extremely difficult, but “something” was there. This time, it was more round, so clearly being closer to zenith (74 degrees altitude) meant less gunk was between my eyes and the comet.

That is where things got interesting. When BA-14 moved toward magnitude 11 star HIP 45137, it brightened just as it did near SAO-98369. I observed a more round object instead of a spindle and the strain on my eyes was significantly less.


I don’t know much about these kinds of observations and those of you who like double stars, asteroid occultations, and other interacting/overlapping objects may have feedback on what I observed. I have two explanations which might make my observations make sense. The first is that since BA-14 is within our own solar system, background objects like stars emit light toward us and passes through anything between here and there…like a comet. Ideally speaking, one would probably observe a dimming of the background star as the comet passes in front as with any occultation, but it seems that it might also be possible that the star light may pass through the dust. My second and more likely explanation has to do with our eyes and vision. When our eyes focus on dim stars in the eyepiece, averted vision and dark adaptation work hand in hand, allowing nearby dim objects pop out much easier than when observed directly. Whatever the reason, my observations were logged and one more comet has been knocked out as I attempt to complete the first tier of the Astronomical League’s Comet Program.

I’m awaiting astrophotography shot by a fellow SBAS member to really compare my observations with what can be captured with more sensitive equipment.

Comet 252P/LINEAR is next on my list. It’s worth noting that astronomers think BA-14 is a piece of 252P.

Messier’s NGC Equivalents

While learning to operate the club’s older 8 inch Meade LX200 which was donated to us, I came across a section in the manual about touring the night sky. There is an option in the hand controller to select from the various kinds of deep sky objects and go on something of a tour, bouncing from one object to the next at whatever pace you choose. It allows a user to view galaxies, planetary nebulae, globular clusters, nebulae, open clusters, or any combination of those five as long as the object is in the telescope’s catalog. The problem with that is, the LX200’s catalog is small and we cannot find the upgrade chip for that model.

Our club had a scheduled session for members which didn’t get the turnout I had hoped, but our goal was to introduce telescope designs and show people how to operate those telescopes afterwards, beginning with dobs. I chose to come out to teach people how to use the LX200 in hopes that I would expand the number of available members competent enough to operate it for a public star party.

Like I said, the turnout didn’t meet my needs, so after most of those people had left, I went about learning how to set up this “tour” via the hand controller.

Once I figured it out, I selected planetary nebulae and globular clusters to keep it simple. The Meade selected its first NGC target, NGC650. NGC650? I had no idea what NGC650 was and I’m usually fairly good at remembering common NGC numbers. For instance, if I need to find the Cat’s Eye Nebula, I know it’s NGC6543. But NGC650? Never heard of it.

So I let the scope slew to 650 and it stopped. I looked into the eyepiece and saw a dim fuzzy object that didn’t really show much of a shape at first. It appeared somewhat lobed, albeit small.

Skysafari to the rescue!

NGC650 is actually Messier 76, aka the Little Dumbbell Nebula.

I looked back into the eyepiece. Yeah. That was the Little Dumbbell. The hand controller did not show the object info in Messier numbers. Instead, it displayed things as they are in the NGC (New General Catalog), even though it can show me all 110 Messier objects by inputting Messier numbers.

Another club member came up and I explained what I had learned. I slewed to the next NGC object, NGC6853. No idea, right? He looked into the eyepiece and was impressed by the view. Nice one. I looked at where the scope was pointed. Dumbbell? He said it wasn’t. I had a look. Yep. Messier 27.

Next? NGC6205. Not a clue. Which one was it? Messier 13, the Great Globular Cluster in Hercules. Of course, it was. NGC6207 is the small galaxy right next to it. I should’ve known!

Some amateur astronomers are quite particular when it comes to object naming schemes. Some turn their nose at common names, giving preferential treatment to Greek terminology. Some don’t know there’s a whole world outside of Messier objects nested away in the vast NGC or IC catalogs. Others aren’t familiar with Collinder, Trumpler, Stock, or Mark catalogs. Still, it is time for me to learn the NGC numbers for Messier objects because, as far as I can tell, most of us don’t have it saved in that format.

If you like the Needle Galaxy, you’ll like NGC5746

There are rarely instances where amateur astronomers venture off script and discuss deep space objects that are not on the list of usual suspects. On the list of needle-like edge-on galaxies, we have the Needle (NGC4565), the Whale (NGC, NGC891 in Andromeda, or M102 (Spindle/NGC). The Needle Galaxy is obviously the leader of the pack, especially if you do a search on edge-on galaxies. NGC891 with its dark lane down the middle comes in at a close second.

Every so often, someone like me working on faint fuzzies comes across a surprisingly bright galaxy under skies just outside of a city where light pollution can still interfere. A few nights ago while working on the Herschel 400, I came across one such galaxy, NGC5746. It sits adjacent to 109 Virginis, so close in fact that I had to move the star out of the field to better enjoy the view of 5746.

NGC5746 is an edge-on spiral in the magnitude 10 range, but it has a bright 2 arcminute core and a 7 arcminute halo according to SkySafari. It certainly can’t compete with the Needle, but the bright core alone is enough to make you consider adding this to your observing list. I found it somewhat easier to see than NGC4565 and definitely easier than NGC891.

We spend an inordinate amount of time bouncing around Virgo in search of galaxies because that constellation is loaded with them, but I have a sneaking suspicion this one is probably not one you’ve observed. You might even want to photograph it. I can guarantee your friends have not logged this one visually or via astrophotography. Go off script for a change.

Here's a wide field chart to show you where 5746 is located. In this view, you can also see Arcturus, Spica, and Antares.

Through the Stargate

Among the various lists offered by the Astronomical League, one stands out as probably the least understood, the less often tackled, and yet the most imaginative. This list is the Asterisms Observing Program. An asterism is simply a catalogued grouping of stars which bear a striking resemblance to something. Some asterisms are more obvious than others. The Big Dipper is an asterism inside the constellation Ursa Major, for example.

Many conversations at regional star parties have led to discussing this list and its challenging nature, often coming to the conclusion that lots of star-groupings do not appear as described and a vivid imagination is required. “I don’t see it, but” seemed to be a common saying among people who have attempted and/or completed this list. Whether those you meet along the way think fondly or negatively about this list might ultimately decide whether or not you attempt it yourself.

The mere task of going through this list, to me, has the same appeal as tackling the Herschel 400 just through sheer quantity. Like with many AL lists, there are observable objects amateur astronomers likely never knew of prior to skimming through the asterisms the AL wishes us to observe and log. However, one asterism has come up in the aforementioned conversations which has a social reference likely not apparent to those under the age of 40, unless the sci fi space nerd in them has gobbled up all the science fiction series’ possible.

Did you ever watch Buck Rogers?

I was an 80’s kid and so any TV show from that era, whether early or late in that decade, likely holds a special place in my heart, animated or otherwise. I never watched Buck Rogers, though. If you were to tell me about a “Stargate,” I would not think Buck Rogers. My “Stargate” reference point is the Stargate SG-1 TV series. An asterism located in Corvus very proximal to Messier 104 resembles the Jumpgate or Stargate from the Buck Rogers TV show, but calling the asterism a “Stargate” obviously won’t make complete sense to someone who hasn’t seen the show. It was named some 30 years ago. (Read more here.)

Star hopping to M104, for me, involves pointing my finderscope at Delta and Eta Corvi, zig zagging up to a triangular arrangement of stars, then to a line of stars in an L called the Jaws asterism, then to M104. In case you were wondering, “Jaws” is another asterism I can’t quite picture with my imagination, but that first arrangement of stars on my way to M104 is the Stargate. Not knowing it was an officially named asterism, I always thought it looked more like the Flux Capacitor from Back to the Future than anything else and so that’s what I tend to call it in passing. To me, a Stargate asterism should appear round since a Stargate in my mind is what I saw on SG-1.


Stargate Asterism: (Wikipedia Page)


Crop of asterism in SkySafari Pro

I’m assuming this is a close approximation to a Buck Rogers Stargate:


Flux Capacitor:


Stargate SG-1:


On a more serious note, the asterism itself is a multiple star system cataloged as Struve (STF) 1659. If you fancy sketching this target and want to identify the primary for determining position angles and whatnot, head on over to this page by The Belt of Venus. That astronomer has done the work for you by labeling the multiple star system on the sketch log.

If the asterism is what a Stargate looks like, I can’t help but amuse myself at the thought that the way to starhop to M104 is via a cluster of stars named after a wormhole.

The Jaws asterism, on the other hand…

Upcoming Presentation: Caldwell 70/Astro League Programs

It all started months ago when another member, then club president, suggested we team up and do a presentation at one of our club meetings to introduce the membership to Astronomical League programs. The process of completing these programs remains somewhat mysterious to many of our members for some reason. The work involved also seems intimidating to them. A presentation showing how it all comes together could break a few barriers and bring in a few more participants.

The plan fell by the wayside until our new club president sent an email out to the three members who have been working on AL programs the most, myself included, asking if we’d like to do a presentation. It all amounted to each of us tackling what we wanted however we wanted. I was left with thinking I should present the Caldwell list as it is a difficult undertaking requiring a trip to dark skies and attention to NGC objects low in our Lat 32° sky. I began the Caldwell Program in February of 2012 and finished at the Okie Tex Star Party in September of 2013, so the list required more commitment than the Messier Program and others.

I am still in the idea phase of making my presentation. The title will pull from my blogging experience, using the same title as one of my posts, Keeping up with the Caldwells. Beyond that, I lack any cohesive organization or format for introducing Sir Patrick Moore’s vision to the SBAS. I will have to cover the rules and regulations for this program, general sketching techniques, necessity for dark adaptation, cardinal point notation, use of nebula filters, some observation terminology, my methodology, and obviously, some choice objects from the challenging list to show what’s on there.

I feel as though a good photo of the pin and certificate is required to really lure them in. I love AL pins. Acquiring new pins keeps me motivated.

Caldwell 70 Pin

And then you have Sir Patrick Moore. My introduction should at least explain who he is and emphasize as the AL site does why he chose these objects for his list. After all, he was aware that these objects were not catalogued by Messier. Many amateur astronomers know quite a few of these objects already and even stare in awe at astrophotography images of them, yet if you were to ask them to manually hunt those objects down, what do you think would happen?

The only worry I have is that it will not come across as exciting, so I will need to work on spicing it up so that I don’t put my audience to sleep. I’ve got no fear of public speaking and am comfortable in front of this group, but I also know that this group has resisted the AL program challenge on every level. It will be an uphill battle, so I hope I can find the right triggers to inspire at least a few people.

When life gives you lemons, split double stars.

If you have ever met me at a star party, one of the first things that might come to mind is that you know I am a dedicated observer. At Okie Tex when we endured cold temperatures and wind chills, I was bundled up in my heavy coat knocking off items on the Okie Tex challenge lists. My observation logs from that night reflect my behavior. Every 10 minutes, I logged an object. In between each, I was huddled inside my tent warming my hands and body up for the next attempt. At Hodges Gardens last year, I wanted to see Caldwell objects I couldn’t find at home. Despite the clouds and wind, I stuck with it and knocked out quite a few Caldwell objects, including a few tiny mag 13 galaxies.

Tonight was no exception.

Earlier in the evening, I went outside to set up for some Herschel objects. Unfortunately, because of the moon glow, I had difficulty finding an open cluster I wanted to sketch. By the time 9pm rolled around, clouds were overhead. By the time I had packed it in, the clouds had disappeared.

Two hours later, I went back outside to observe. The moon was setting in the western sky. Only a few small clouds lingered in the northern sky. I was able to sketch two more objects on the Herschel 400 list before clouds came in and killed off any chance of dedicated sketching. Those two objects were NGC2158 and NGC2129. I couldn’t find NGC2126.

What’s an amateur astronomer to do?

While I have completed the Binocular Double Star list, I still need to do the full Double Star program from the Astro League. The log forms only require conditions, descriptions, and a sketch of the pair in question, paying attention to North and noting West on the diagram. Double stars are one of the few things we can observe in tough conditions as long as Seeing is decent.

So that’s what I did. By 4am, I had sketched and logged 13 double stars on the program’s list.

By the way, the best do-it-yourself add on I’ve made for just such a hunt is an aperture mask. I’ve made a cover out of a foam sheet with about a 2.5 inch hole in it. This puts my scope at roughly f/19 and airy disks form around stars. Not only that, but tight pairs clean up and colors come out. For example, tonight, Alnitak’s companion only appeared blue to me once the aperture mask was applied. Rigel was easier to split. Theta Aurigae was much easier to split, too. For fun, I even had a look at Jupiter because, although the mask reduces resolution, it dampens bright objects, so Jupiter looked clean. I saw the GRS and two moons.

But I’m done for tonight, folks. The clouds came in and killed my view of everything. I was just about to sketch Mizar.

November 26th and 27th Recap

The dark skies set in early this time of year, so I could not resist setting up the XT8 to show my girlfriend a few DSOs these past couple of nights. Late on the 26th, I enjoyed views of the Double Cluster, M42, M1, and M31/32/110. I even showed her the teeny tiny NGC1999 at about 150x. On the 27th, I was able to put a few other objects in view during a run & gun observing session including the Helix Nebula, the Fetus Nebula, and both Eastern and Western Veils.

The Double Cluster was teaming with stars and the Smiling Cyclops easily caught my attention. M42 filled a decent field and gave some great detail along its wings and central regions. M1 resembled a poof and only subtle detail was apparent. M31 spanned across most of my 35mm eyepiece and M110 appeared twice as large as it normally does. M32 even had a tiny bit of extra halo.

Because the Helix Nebula had already set by then, I knew it would be on the menu for the 27th.

So after setting up on the 27th, I put the Helix in view first. Without a filter, nothing was there. My trained eyes could detect a slight hint of something, actually, but I tossed a UHC filter on a 26mm eyepiece and the Helix instantly popped into view. It didn’t have much quality to it and the central dark region was just barely visible. The fringed ends were not the least bit refined. An OIII filter cleaned things up quite a bit, allowing obvious bias to be apparent on at least one end of the nebula where the edges taper off. The central dark circle was much more visible. OIII made all the difference.

Then she wanted to see the Fetus Nebula. After consulting SkySafari, I put it in view. The kidney bean shaped nebulosity was visible at low power next to a star in my 35mm eyepiece without any filters. At 70x and 150x, the nebula was obvious and one end was brighter than the other. An OIII filter only made it brighter, so again, an OIII filter made a difference. Best view of NGC 7008 I’ve ever had.

And then I wanted to view the Veil Nebula, so I put in the 26mm eyepiece with the OIII and ran on over to 52 Cyg. To my surprise, the handle of the broom on the Western Veil was easily visible and the rest of the broom came into view on the opposite side of 52 Cyg. It wasn’t Okie Tex quality, mind you, but I cannot recall the last time I saw both parts of the Western Veil at home. The Eastern Veil yielded similar results with some fibrous quality and that curled end coming out with an OIII filter.

Not bad for a couple of nights observing. My OIII filter is the inexpensive Zhumell OIII and not the prized Lumicon everyone raves about. My eyes are trained after observing under dark skies, but my memory often needs refreshing, so the hunt always breathes something special back into my lungs and awakens the senses. Things like knowing NGC numbers and choosing an OIII filter when all else fails makes me the kind of observer people respect, but knowing what to look for once I get where I’m going makes anyone at my eyepiece a better observer, too.

How well do you remember your observations of the Veil? Fetus Nebula? Helix? Crab Nebula? M42? If you are a visual observer, this is one skill you absolutely must foster in yourself. I don’t want to knock astrophotographers, but the visual observer is often the better amateur astronomer.

Helping you through the Binocular Doubles List

When considering challenges in our hobby, one place we turn is to the Astronomical League’s lists because they are both varied and comprehensive in nature. If you enjoy telescopes over binoculars, planetary nebulae over solar viewing, or constellations over Messier objects, or conversely, the opposite of any of those choices, the AL has a list for you. However, those lists are not always clear and sometimes, you have to do some of the ground work to sort out what they put in front of you.

The Binocular Doubles list is one challenge I have almost completed. I have eleven more double stars to split and sketch. The list itself contains standard nomenclature, but also throws in the two flavors of Struve objects, Herschel doubles, Dunlop, South & Herschel, Knott, and South by way of Greek symbols. If you use star charts, seldom are these double stars listed by these Greek names.

That’s why I have chosen to write this post. Think of it as a reference post rather than an article. I have taken the time to look up the oddly named stars in SkySafari Pro and considered position angles in determining those primary and companion stars. If you can search for HD, SAO, or HIP items in your star atlas of choice, then my work will probably help you complete this list.

Let’s go alphabetically using the Binocular Doubles List. I will include the AL designation from the list, the constellation the pair is located in, and the naming scheme(s) to search in SkySafari. I have bracketed pairs in the nonstandard catalogs for convenience. What few I have not figured out yet are noted with question marks and clarification is needed. The list below isn’t perfect, but it’s close to being complete and is most certainly useful if you plan on tackling this challenge.

The easiest way to verify the correct companion at the eyepiece or in a star chart is to use the position angle listed in the AL list. Draw a 360 degree circle around the primary star. Label North as 0/360, East as 90, South as 180, and West as 270. Eyeball estimate the angle at which a possible companion sits and then compare that to the number quoted on the AL list. If you guessed correctly, you should have the correct pair of stars.

If you spot any errors, please let me know.
