Hey all!
I am new to forum, and I have a question surrounding my gear and astrophotography. I am using a nikon d5000 along with a tamron 70-300mm telephoto lens, and am attempting to photograph deep sky objects by taking a lot of exposures and stacking them in deep sky stacker. Being that Nikon d5000 is a pretty old camera, and has very limitted ISO range, I am having trouble capturing deep sky objects. I can capture them well at about an 8 second expsure (at full ISO of 6400 and opening up the aperture) however at this point star trails become visible whenever I am closer than about 150mm of zoom. I know that most people take about 2s exposures when not using a star tracker, however this is not sufficient for my camera to capture the object. Any tips or ways to get around this problem without purchasing new gear?
