Comet C/2012 K1 (Panstarrs) and NGC 3877

This past year have brought us some exciting celestial wonders,and great science knowledge have been achieved. I am talking about comets. Their have many opportunities for all of us to explore,and grow. Some comets have been just quiet wanderers.,never getting their chance in the media lime light. They come into the inner solar system, seemingly “guns blazing” ,and then quietly return to the outer reaches,never to be seen again in our life time. Others, get noticed right away,and a media frenzy begins. People speculating (mainly media) ,about how bright or how big of a show it will be. Comet ISON was a prime example of the over hype from the media. ISON put on a good show for it’s final journey. The sad part of the over hype ( IMHO ) is,most people get excited to see a amazing sky show,but when the event ends, people just go back to their daily (or nightly) routines,like a arm chair quarterback. Never giving thought that,just because one event has ended. doesn’t mean the arena has been shut down. Their are still wonderful objects in the night sky that are putting on their own show.

Yes, their are some comets in the Northern sky that are visible. Two comets are on display in the Northern sky,and located near the constellation Ursa Major a.k.a… the Big Dipper. Both comets are within reach of small telescopes. Although, one of them, Comet Linear is a dim mag + 11.61,and might be difficult to see in a small scope,depending on sky transparency. The other one, Comet Panstarrs is much brighter at mag + 8.4 . Comet  C/2012 K1 (Panstarrs) can be seen as a faint,but distinguishable gray smudge. This smudge gets brighter as your eyes adjust to the darkness. I had known about these comets for some time,but time,and cloud cover had put them on the back burner. Leaving me with only small windows of opportunity to observe the other wonders of our solar system and beyond.

With the forecast of clear skies last night. I decided now was the time to check out one of the comets. I chose comet Panstarrs as my target,as I felt it would be a good time to check my mounts goto accuracy. By the way….. it performed flawlessly!!. I entered my observatory at around 9PM last night. The sky was a tad bit light to the west due to sun setting 45 minutes earlier,and the stars were just beginning to show themselves. It took a while to actually see the “gray smudge”,but when I did see it. I knew I had a comet in the eye piece. It took a short while later before I decided to connect the CCD to the scope. This turned out to be a fiasco…LMAO!. The stars were nice and round ,but as each image was acquired,and stacked. The comets nucleus on the stacked image became stretched,showing multiple heads. I haven’t down loaded the final images yet,but will when I have a few extra minutes to spare.

After a couple hours of trying,I went to my backup camera. The DSLR for some prime focus imaging. This worked out quite well I must say!!. I snapped a couple test images to check my focus,and nailed it the first time!. The temp in the observatory was getting getting cold,so I opted for only a couple shots before shutting down. I managed a 4 and a half minute unguided exposure without star trails.Since the screen on my dslr is small. I didn’t get a full look at my work until I loaded the images onto my laptop. I must say “WOW”!. The comet was green as I expected. What I didn’t expect was to get the galaxy NGC 3877 in the same shot!. NGC 3877 appears dim,but in my defense. It is after all, 50 million light years away!!!. 

Comet C/2012 K1 (Panstarrs) is expected to brighten in the next few months,making it almost a naked eye comet. I really doubt that, as it is quite small,but one can hope!.
