Very nice.
Nothing but clouds (or -20 degrees) so couldn't help downloading uncropped fit and have a go at processing.
Feeling a bit rusty but here goes.

Thanks Tapio/Nikao/Joe.

Tapio, your rendering is really nice; you could brighten it a bit.

Nikao, I agree, on a closer look it does resemble a well-built man with two arms and no head. Thx

Nice shot, but a bit noisy. Ever try ISO800?

This was an all ISO 1600 deal. Noise is mainly coming from aggressive cropping; high res. full frame... has lesser noise. Would try ISO 800 on the next opportunity. Thx

Thanks Zach/Erik.

Mike, your processing looks very nice; I like the colors in NGC 2023 (at the base of Horsehead). Thx
