Brightest Comet in the Sky – Don’t Miss It!
Dennis Persyk <dpersyk@...>
C/2007 E2 (Lovejoy) is nearing its peak on light curve – see
http://www.aerith.net/comet/catalog/2007E2/2007E2.html This is presently the brightest comet in the sky (save for a few lucky souls near the equator who might still be able to view 2P/Encke). Better grab a view or an image now, before it fades into oblivion. It is racing though Aquila at 8.8 arc seconds per minute at magnitude ~ 7.6. I was limited to 30 second exposures when I imaged it to avoid blur. I "think" I saw (using averted vision and averted imagination) the comet in my 4-inch refractor piggybacked on the 6-inch E-160 f/3.3 astrograph. I synthesized a simulated eyepiece view for my web page linked below. I was baffled for quite a while looking for the "missing star", V606 Aquilae, that was depicted prominently in my SkyMap Pro screen shot as being very bright but was missing in my image – even though all the other stars were right where they should be. How could I not image a bright star??? The mystery (for those that haven't figured it out yet) is solved on the web page. Let me know what you think of the movie. It really was hard for me to get the hour's worth of frames to look about the same. The comet was rising in the sky (and thus getting brighter as the atmospheric extinction was decreasing); at the same time, the sun was rising, so the sky glow was increasing. Balancing the two effects to achieve consistent histograms drove me nuts! I've probably invested ten hours in image processing and composing the web page. Images, associated data, eyepiece view, imaging notes and *movie* all at http://home.att.net/~dpersyk/new.htm Please take a look and give me some feedback. This was quite a processing challenge for me. Thank you for visiting my site. Clear skies, Dennis Persyk Igloo Observatory Home Page http://dpersyk.home.att.net Hampshire, IL
