content: Just a quick and dirty video of the comet as it flies through our solar system for a few hours. I was going to take more images tonight but we have a rare cloudy night.http://youtu.be/CCB6kdJ27M8

content: Oh, it's not real time, eh? I guess I ought to have realized anything in the night sky showing apparent motion to my eye would be a meteorite. Thank you for showing me. What kind of telescope did you use? Do you remember the coordinates? I am very fond of astronomy. I did manage to view Halley's comet during its last perihelion.

content: Under the video he said he used a Canon 7D on an Orion ED80.Nice video. It's too cold here in the north now to drag out my Mead 8".

content: Quote from: ee851 on February 04, 2013, 01:02:16 amThe telescope is an Orion ED80, 600mm focal length, f7.5. I also have a field flattener on it. It is an apochromatic refractor with high dispersion optical elements that almost completely remove chromatic aberrations.Quote from: ee851 on February 04, 2013, 01:02:16 amhttp://mpcapp1.cfa.harvard.edu/cgi-bin/returnprepeph.cgi?d=c&o=CK12F060you need to enter this information in a planetarium program likehttp://www.ap-i.net/skychart/and see where the comet is at any specific time. This one is over the south pole so unless you live where I am in latitude or more south you will not see it.

content: That's great. You're lucky to have such clear skies.7th magnitude right now at 0.99 AU and it's supposed to get to 2nd or 3rd magnitude in March at 0.7 AU. Northern hemisphere won't get a look until April.Enjoy it, it won't be back for 11,000 years!

content: Nice video!Have you encountered the 'Electric Universe' theories, including the nature of comets as an electrical/plasma glow-discharge around a primarily rocky body, as opposed to predominantly water-ice body?It's quite interesting.

content: Wow, nice video! I really envy you on dark and clear skies you have down thereMy astrophoto equipment is gathering dust for months because of bad weather/Moon/lack of free time and all possible combinations of that...

content: Quote from: TerraHertz on February 04, 2013, 09:45:27 amLots of links on that page and not enough time to read them all. I do know that there have been a couple of missions to comets and the data and samples still point to predominantly dirty snowballs.

content: Yeah, dark skies and clear on average of 320 days per year are some of the reasons I moved here. Unless you are further south than the equator there isn't much chance of seeing the comet right now. It is also just below the threshold of naked eye observation.
