Like a lot of astrophotographers, I get repeated questions on how to do things that although may seem simple, I have to remind myself that they were once beyond me... So last night, I sat up all night and stacked some images in Deep Sky Stacker, taking screenshots all the way and writing down what I did as I went. Hopefully this can answer a lot of questions and get the new blood in the game well on their way to adding to the richness of images proliferating amateur astronomy. http://www.asignobservatory.com/index.php?option=com_content&view=article&id=84&Itemid=125 Have a crack, enjoy and let's see what you new folks can do!!! YEEEHHARRR! Baz.

Well done, thanks for the contribution. So far I've only done a few webcam and solar system images. Appreciate the info on how to use the Deep Sky Stacker program.

I don't own a DSLR, but might try it with another Canon digital camera I have that says it goes up to ISO 1600.

No worries mate. Good luck! Baz.
