Rosette nebula + L-Extreme

[MarkInSpace]

I made a 2 part panorama of the Rosette Nebula using the Sky Rover 115+L-Extreme+ASI204MC.
I used Pixinsight + Topaz Denoise + Microsoft ICE

The top section was 28 x 300s subs
the bottom section was 6 x 300s subs

Nice image but you need to fade topaz denoise as it's a little overdone you can see artefacts in the stars

Haha thanks - i think that’s my lousy compression - to get the image under 200KB I ended up saving the image at 20% jpg!
What’s a better choice?

In photoshop I use export to web and resize according to pixel numbers (usually 1400 across) that helps with the compression artefacts

Mark, you can post images up to 2Mp and IIS will compress them down
to 200Kp or less.
