Hello. I'm looking to send a weather balloon into the atmosphere and take some interesting shots along the way. I realize alot of people have already done it, but I'd like to try it for myself. Being that I know almost nothing about photography, I would like some opinions on an ideal camera to send up there. I have about a $300 dollar camera budget, and I only want to do this once, so I really appreciate any opinions I can get. I'm really interested in the near space shots, so that's what I would like to design my rig around. I don't know what time I'll be sending it up, but I think the dusk / dawn photos will be the most interestings, so I'll probably release the balllon accordingly. I think I need a camera with good stability, good autofocus, a large aperture, a continuous shot function, and an ability to function correctly when it's cold. Any ideas? Thanks in advance!
