Two weeks ago (new moon) I drove 8 hours to a dark site.

I was going to shoot from two rigs left and right.

It didn't go as planned.

It was very smoky from the recent California wild-fires.

 

I didn't even set my main rig (computer-controlled with plate-solving, auto-focus and guiding) up since there was almost zero visibility.

Now I regret that I didn't set it up... : (

By midnight the sky cleared up and it was gorgeous!

I quickly assembled my secondary rig (DSLR, AZ-GTi, SynScan app and SkySafari, no guiding) - wide-field. And started shooting.

Next day was smoky again so I left...

A bit disappointing considering 16 hours of driving (round-trip).

 

I was only able to shoot one object - the Question Mark complex (NGC 7822, NGC 7762, Sh2-170, Sh2-172)

New object for me, so it was worth it after all.

 

AZ-GTi mount, modded Nikon D5500, Nikon 180 mm lens at f/2.8, ISO 400. IDAS LPS-D1 filter. 160 x 60s.

Bortle 3.

No flats, no darks, no bias. Processed with APP plus some Photoshop.

Not great but OK. Polar alignment was not perfect.
