Nice, I think I got this in my wider view of the Prawn

Nice work, Doug.

How much exposure in total?

Thank Trevor - that's how I found this object, whilst out Prawn fishing!

Cheers...RGB channels 10x120s each, and around 5hrs Ha data split between 6x600s and 15x1000s exposures. Just rechecked the subs in Blink...they really weren't the best - thin clouds on many subs. I'll have to revisit this object again soon

Great data capture Doug,
it would be nice if you could get some of that detail in the Ha version
into the colour version.
Did you try a Ha Luminance layer?

cheers

Hi Doug. That starless image is indeed striking.
I've been shooting the same object with mixed results.
I would appreciate it if you would reveal your star removal tool/technique.

If you remove the stars from the colour version then use the mono as a lumininace layer then return the stars this image will pop!

Thanks Peter - StarXterminator to remove stars from the original Ha image
