Heads or Tails?
Heads or Tails?
Processing the image of a comet can be tricky. It's something I don't have much experience with. The head is bright and the tail is faint. I need to find out how it's done. Here is a happy medium depiction of Comet Lovejoy.

That's a great image of Lovejoy, Steve!

Re: Heads or Tails?
Thanks Mike. I believe that there is a tiny galaxy, about a comet head's width back, within the tail. Photo was taken around 7pm on January 13. Maybe someday I'll find the time to identify the galaxy.

Re: Heads or Tails?
The tail is so long (20 full moon widths at last count) you can't help but cut it off!
It's about time we got a break and finally got a stunning snowball.

Very nicely done, Steve.
I'm trying to learn how to process comet data too.

Re: Heads or Tails?
That looks good, Bill.
I was wondering if those rays might be lens flare artifacts but I now think, after your application, they definately
aren't. Nice work! Same to you, Steve!
This snowball is really getting our brain cells working!

Re: Heads or Tails?
Steve, your galaxy is PGC 1399248 mag 17.1. It is considered an unconfirmed galaxy, but in your comet photo it sure looks like a galaxy to me.

Re: Heads or Tails?
Here's another take on Steve's great image.
Steve, your pic has SO much info in it!!!
I take back everything I said about over-exposure.
You were expertly collecting tail detail!
Keep shooting!
