I tried my hand at some star shots last night, having missed the scheduled appearance of the ISS. Don't know if I got the time wrong, or the direction, but I was all ready for it and it didn't come. It would be difficult for them to 'reschedule' or 'reroute' it, so I guess I screwed up somewhere...

Anyway, I took multiple exposures of each set, planning to stack the images. Turns out the program I have doesn't align the star images, so you get a line of dots. I am posting my first test shot, of Orion coming up over a roof. The bright object to the lower left is Jupiter, and above that are the twins of Gemini. You will probably need to download it to see most of the stars.

Obviously, this isn't the look I was going for... Can anyone suggest a decent (cheap!) program which will align the star images? I know the roof in this particular shot will be an issue, but I have some better ones.

Hello Bloke, My first question to you is,What mount were you using? Was it just a non tracking tripod? If so, all you will get is star trails. I apologize if you were already aware of this yet you did not state all your equipment used.

Yes, all I have is a standard tripod. I know that there is software out there which will allow stacking of images, though. I actually tried one, which stacked 2 out of 3 images, but left the third one hanging, and I have no idea why.

I am gradually improving my equipment, but a tracking mount is a long way down the road for me just yet.
