Steffan, I use maxim dl for that because it is written specifically for astronomy
http://www.cyanogen.com/downloads/maxim_main.htm but you could do it in photoshop - if you do it in photoshop, you are going to have to create a whole heap of layers, manually align which will entail rotating as the comet slides down and left in the images..and use screen as your output - very time consuming. If you download the demo and use it, when you load the images into the prog, click on process, then click combine. It will ask you how you want to align the images and how you what to do with output - box on bottom right, so click one star manual and sum. You will then have to manually click on the coma in each frame and then after you have done this for all 10 shots, sit back grab a cuppa and let maxim do its thing. You will produce an image which will need adjusting with the levels box but after that it should look much better than the individuals - lots of detail in the tail. Save as a jpeg 100% and make sure you tick the box on the bottom left which asks you if you want to automatically clip, if you do not do that you will not be able to open the image in anything else. Open in your prog of choice, crop and you are done..
Hope that makes sense...if not send me a message and I will try and walk you through it.
Trying to share the love of astronomy!!!
