Night-sky newbie here!
I attached my nifty-fifty the other night and took various 35 second exposures, typically at f/2.2, ISO400 - bulb - remote shutter release
But in Live View using manual focus (10x) I was unable to get the focus I wanted - I had it turned all the way... to infinity I guess - and it seemed like it could have been sharper yet
If anyone else has done shots with their 50mm f/1.8 please share your successful settings... I imagine I was getting star-trails after about 8 seconds or less. 40 secs certainly showed the beginnings of trails.
I guess I will go back to using my 15-85mm - likely at 15mm f/3.5
Thanks for any tips. A processed shot with the above (top) settings is attached
