Re: Struggling newcomer looking for guidance

Here you go. Not everything I did is strictly approved (using the Superstructures module with a mask to cut back the noise, for example) and I had to have several goes at cropping to deal with the gradients. The very last develop module is just to get the histogram away from the left edge (I think t...

Re: Struggling newcomer looking for guidance

Thanks for posting your data. I had a go with the latest edition (as of this afternoon 1.7.434) and the result is below. There were some quite strong gradients which were cropped out and to speed up processing I binned to 35% although this wouldn't be something I'd normally do on under sampled data....

Re: L-eNhance star colors

Watching this thread with interest as I have started to accumulate some bi-colour nebula images, but (as expected) the star colours are completely washed out. I have some nice RGB stars and pretty sure that if I knew enough about the layer module (surely one of the great features of StarTools) it wo...

Re: WEIRD ARTIFACT

From the orientation of your image, it may be a reflection off something in the imaging train of the bright star Rigel.

Not sure what can be done about it though, apart from fixing it in post processing, a longer dew shield perhaps?

Re: l rgb and ha

Ha ha, I know that feeling!

I have resorted to extracting info like this from the posts, editing it and then storing it in small .txt files in the Astronomy folder. Currently got about a dozen :-)

Re: question about LRGB

Not sure about YouTube videos, but to get DSS to stack two separate nights so that they can be used together in StarTools, you stack the first night as usual and make a note of the reference frame. This (if you don't intervene) is usually the one with highest score and the one with 0 offset values. ...

Re: sgl processing competion

Thanks, Ivo, think I've got it now.

Back to pursuing that faint blue bulge at the lower left part of the nebula - yours looks wonderful - mine not quite as good yet but with a week of solid cloud in prospect this will be a good chance to improve!

Re: sgl processing competion

.. If O-III is of particular interest, have you tried Matrix in the Color module with dominant O-III coloring? (for example SHO 20SII+80Ha,20Ha+80OIII,100OIII), or tried compositing the SHO dataset with O-III weighted more highly for the synthetic luminance? This has been a most interesting thread,...
