After opening the observatory I prepared the D7200 DSLR for piggyback imaging.

I mounted the D7200 DSLR piggyback on the 12" LX600 telescope using the ScopeStuff Camera Mount.
I then relaxed on the observatory patio bench to wait the stars come out.

Slewed to the star Deneb, SYNCed the AutoStar, and focused the 70-300mm lens on Deneb. Then slewed to NGC7000 (North American Nebula).
2052 MST: StarLock ON.
After doing some framing tests I took this StarLock autoguided, piggyback image of NGC7000 (North American Nebula), f/5, 5 minutes, ISO 4000, White Balance 5560K, Focal Length 70mm, slightly cropped.
Slewed to NGC6960 (Cygnus Loop Nebula). Did some framing tests. This is a StarLock autoguided, piggyback image of NGC6960, f/5.3, 1 minute, ISO 6400, White Balance 5560K, Focal Length 210mm, slightly cropped.
