Nice to see another shot at this, the only other one I've seen around is Damian Peach's which is predictably great yet out of reach of us mere mortals Hence I'm pleased to see your take on it.

I presume you have done two stacks and combined them, one for the comet which would have moved significantly during 1.9 hours and one for the galaxy?

Nice colour balance.

My only suggestion would be to process such that the centre of NGC 1291 is less burnt out.

Thanks Roger. There's a couple of other pics of it in comet watch.

Yes same data but two stacks combined. They are not easy to combine well and it takes time. DSS does it, but badly. I only bother when there is an interesting field.

Yeah the galaxy core is burned out and the stars bloated. Something I'll get around to fixing some time lol.

There's a conjunction with 47 Tuc on August 30. That will make an interesting composite.

I'm interested to hear you say that. I have tried it in DSS myself in the past and thought it didn't do it well, but thought that must just be me. I did find it time consuming to do a stack like this.

Thanks for the heads up, I'll have to prepare for that and put it in my calendar with 10 reminders so I don't miss it, it could look awesome

Hey nice picture cometcatcher,

Now i am wondering how do you see comets. I've always wondered how to see them. Can someone explain how to see them or is it too hard too try and get them.

Kind regards,
Frostyricho

Thanks Justin. I'm a wuss in the cold, but the camera likes it. It rarely frosts here in the tropics.

Thanks Frosty. Well, comets are much like other DSO's except they move from night to night. You need a webpage or planetarium program to find them. Most of them are very faint. Best to try for the brighter ones mag 6 or brighter to start with.

The best webpages to look at are http://cometchasing.skyhound.com/

http://www.aerith.net/comet/future-s.html

And http://theskylive.com/

Good luck with the hunting. You need patience though.
