Stephan's Quintet and NGC 7331

Post by Stefan B »

Hi everyone,

during the recent good weather period I had the chance to image Stephan's Quintet and NGC 7331 for one night. This was the result:

Image

Since the galaxies are quite small (or rather far away, right?) and I only have 750 mm FL at hand, the image is heavily cropped. But I think it turned out not too bad. For details see https://www.astrobin.com/8zo98h/

@admin I repeatedly noticed recently when processing galaxies I am missing a little feature. The automatic star mask is a great first approximation but when reviewing the mask in order to unmask a galactic core or a detail within a galaxy, it is hard to discern if a star is underneath the green mask or non star detail. Thus it would be handy if there was a button to blend the mask in and out. Would this be possible?

Regards

Beautiful shot!

When I need to check underneath I'll usually do a temporary invert. Though I guess it depends exactly what you are trying to unmask/mask.

Thanks, Mike, that sounds like a good workaround!
