Re: Combining OSC star colours with L-Extreme dual band nebulosity?

I think the mask is the issue, I need to tweak it a bit more but it's difficult as it keeps blotting out nebulosity in the process. Onus is on me to learn to use it properly! If you extract the stars as per the first part of the procedure here https://forum.startools.org/viewtopic.php?f=7&t=244 tak...

Re: Combining OSC star colours with L-Extreme dual band nebulosity?

If you load OSC / DSLR data with linear, not white balanced (2nd option) it will by default start Compose module, loading red pixels to R, green pixels to G and blue pixels to B. So you only need to load this once for RGB. You may add another L file of course or create synthetic L from Compose opti...

Re: Combining OSC star colours with L-Extreme dual band nebulosity?

Not sure which thread you found, but if it was this one https://forum.startools.org/viewtopic.php?f=4&t=2003&p=8776&hilit=RGB+stars#p8776 then the process used was to extract the RGB stars and save them, possibly with increased saturation. Create a mask of just the stars and save it. Now load the L...

Re: Combining OSC star colours with L-Extreme dual band nebulosity?

Ok so I have found a thread suggesting I process both separately, which I have done, then bring into the layer module (L-extreme as background) then create a star mask and blend using colour of FG. Trouble is, with the star mask as-is, I don't get the foreground star colours - the only way I can is ...

Combining OSC star colours with L-Extreme dual band nebulosity?

I would like to achieve the above, but I know not where to start! Is this even possible? Is it a case of using the L-extreme data as the Lum and somehow stripping out the RGB channels from the broadband colour data then doing something clever with masks? Any tips appreciated.
Thanks, Andy

Definitely not, all I did was rotate the mount so the scope was vertical to balance the flat panel. The camera is permanently secured to the scope and focus was identical
