Anybody know of a piece of software that could detect the change the occurred in an image? I'm doing a project to see if I can find an asteroid or comet without any prior knowledge of where said asteroid/comet is.
I'm not really sure where to look for something like this, so any help would be appreciated.
Also, I would like something that could run on Mac. But I'll run it on bootcamp if there is no other options.

Just a reminder for you Shropshire/West Midlands folks, I'm arranging a low-key weekend of Perseid watching and general astronomy antics in Shropshire. Six quid a night, dark sky, friendly campsite. The details and some pictures are on my blog in the sig. Everyone welcome!

A composite image of Comet C/2015 V2 (Johnson) taken in the early hours of April 9th as it travelled between the constellations Hercules and Draco - processed twice in order to show the comet on a background of sharp stars (for purely aesthetic reasons). Because it appears as such a slow moving comet and is more distant than Comet 41P/Tuttle-Giacobini-Kresak, it was possible to take much longer exposures which is something of a luxury.
48 minutes and 45 seconds total integration time
39 x 75 second exposures at 400 ISO
40 x dark frames
31 x flat frames
21 x bias/offset frames (subtracted from flat frames only)
Captured with APT
Guided with PHD2
Processed in Nebulosity and Photoshop

First of all, HAPPY NEW YEAR all at SGL! Wishing you all a very enjoyable, prosperous and cloud free year.
What are people's thoughts on the year ahead astronomically? I must admit I'm quite excited for the months ahead. There's quite a lot going on up there :-) 3 bright(ish) comets, two of these comets will be in the same constellation in April!
All three should easily reach binocular viewing brightness. Then in August there's 'The Big One' if you live in America or are planning on visiting. Even though I wont witness it, I'm still intrigued as to how this will compare to the 1999 eclipse and just what kind of media frenzie the world will get in to on this one.
Any other events people are looking forward to this year?
