Kurt: I fear you are mistaken about the 4 shot limit. That sounds like the limit on the number of rapid fire shots that can be taken before the camera has to slow down and wait for the memory card to catch up. It varies with model and with options in use at the time. The true shot left counter is a three digit number and depending on the model, card size and resolution can often be seen at 999 which means "more than a thousand". So you can shoot all night or all week if you wish and download at your leasure later. Newer models have a "live view" mode that allows you to focus without the aid of laptop software. I use a DSLR to avoid having to take a computer to the field with me. It contains everything needed to do the job on it's own and it greatly simplifies the process.

This would be a general purpose camera but I want to cross-purpose it as an astronomy camera. I feel the cheaper XS model meets my needs.
I am unclear on:
1) For time lapse night time photography of a large sky section with the 15mm lens, how do you get the images off the camera in real time since it only holds 4 shots?
2) Other advice of comments are the purchase are welcome.
Thanks - Kurt
