I have Canon 600d (entry level DSLR) + Dobson 10" and I was trying to follow below instruction video : how to capture DSO with DSLR + Dobson
.... however I am unable to focus any star. I was trying to focus Vega, but in my Liveview was only dark.
With capturing planets: Jupiter, Saturn: no issues, I use TV mode to modify shutter speed ( with planets I used also Barlow, but here nothing helped)
Looks I have same settings ( iso 6400..) but in Liveview only dark... probably I have something missing in camera settings
