NGC2903 RGB OSC

[Padraic M]

This year's iteration of NGC2903, and definitely the best. I hadn't set out to image it again, but it was a matter of dodging the clouds and the moonlight so targets are limited. I wanted to get some RGB Orion data, but it looks like galaxy season has started early! 

4.75 hours of RGB as 57x 300s.

Bortle 2, 60% moon, 30% cloud.
Capture: SW 150PDS, ASI533MC Pro, NEQ6 Pro, Nina, phd2.
Processing: AstroPixelProcessing, Siril, Gimp.

Nice one, decent fov at 750 mm. About the max fl for me too with 3.76um pixels.

Thanks Colm. Agreed, the FOV is ideal or this target. I just cropped out the stacking artefacts. Thought about different composition, especially given the 533's square format but don't think it would add much.

I have some old data including Ha that I may incorporate to see if I can bring out any more detail.
