I'd like to share my first experience with ASI-1600m and Nikon 300/2.8 VRII which I had earlier this year, before covid thing happened.
This is M35 star cluster dominated by bluish stars framed by bright yellow star 5Gem and yellowish star cluster NGC2158, which 300mm lens managed to resolve, thanks to small pixel of ASI-1600mm
The condition were:
Nikon 300/2.8 VRII + ASI 1600mm, gain=0, RGB 4X2min each, L=8X3min, orange zone. Frames have been combined in APP and processed in Photoshop.

Thanks for looking!
