NGC 3371 (middle) Messier 105 (upper) and NGC 3373 (right)

Canon EOS 6D (Baader filter modified)

Celestron C11 at f7 crop.

Mount Sky-Watcher AZ-EQ6

Guiding: None

Acquisition: Intervalometer

Polar Alignment: Polar Scope

Exposure: 45 x 45sec @ ISO-25600 (RAW)

The high ISO was actually a mistake. I usually ramp it up temporarily for framing purposes only, then reduce it to 6400 as my default setting.

I therefore had no calibrating frames as well.

This turned out better than expected. Cheers Mark
