I live in a city with bad air and too much light pollution so I've never really tried to do any night landscapes with star shots. But I'm visiting family in Southern Utah soon and wanted to try some. Ive got my gear list in my signature, can I do these kinds of shots with what I have? 15mm f3.5 bright enough? Should I use my 22mm f2 on the EOS M instead?
I'm assuming wide aperture and medium ISO?
