how do I won at star photography?Seem like everytime I try, I fail hard. If I use 200mm, I get trails. If I use 50mm prime, I get too much ambient light. Pic related.
your lens is only sharp in the center of the field at full aperture.stars dimmer than 9th magnitude are visible (10 times dimmer than what you could see with your eye in a very dark sky), quite good. take lots of short exposures and stack them to build signal to noise ratio
>>83130but how do I stacked multiple exposure with moving stars?
Equitorial Mount + DeepSky Stacker (Program)Other than that, its star trails or nothing :)Have fun
>>83174no it isnt you idiotthere are several pieces of software to do this for youiraf is one of them, you can do it in shop as well, NIH image , XV, etc...
>>83157you need a tracker to eliminate star trails

>>83225Could probably even use panorama alignment software like hugin/autopano.
>>83225Show me a program that autoaligns the stars and corrects for the earths rotation in the software.Stacking images works fine without a mount if you want star trails, But I've yet to see one that auto corrects your alignment
>>83248iraf was mentioned already, or check out the sbig web site or maybe google it newfag
