Hi all, the past 2 days were quite good skies right? I loved it, but i was at the ngee ann poly ANE training camp so i didn't post... so that day, i tried taking a pic using a normal (very, very normal) digicam. Exposure in my cam was 0.0, and i just banged any part of the sky without hope that there would be any stars coming out.

I actually got them from a normal digicam! but they are quite badly done, i am not good with a camera. I only know that since exposure is too short, the bright stars seem not so bright. But I don't understand the why some stars are red in here. Also, how come the stars can be captured in here with such short exposure and a lousy digicam? And if possible, someone help me identify this part of the sky! I took without hope it came out, so I didn't bother which part of the sky I was taking... Thanks for enlightening me!
Anybody explain to me how this worked?!

Hi :
Why not try to shoot at known bright stars ( Sirius, Canopus...) using the slowest shutter speed, manual set to infinity focus and play with the zoom a bit... a tripod might help to prevent..
Most frames will have hot pixels, some digicam will do a dark-subtraction..
Digicam by itself is good enough for twilight shots showing planets.
