+1. Let's hope the starless fashion ends soon; so much good data being trashed!

Here is my starless m52:












Hope you liked it.

Re: M31 OSC + NB accents

Hi everyone What we see, is an interesting one. Colour in particular. Arheim's masterful work 'Art and visual perception' (alianza 1954, ISBN 978-8420678740) deals in depth with how we see stuff and how our mind deals with what we see. It's almost as heavy as trying to process an image in pi. By way...

Re: M31 OSC + NB accents

Hi Nice shot. Went through wipe, color, fringe killer, flux and autodev to keep more faint stuff. Working with the original stack, this should be really good. I'm not sure about the purple stuff in the galaxy arms. Otherwise, I think as you've seen, with the proliferation of false colour stuff, thes...

[L + Synthetic L From R(2xG)B, R(GB)(GB) (Bi-Color from OSC/DSLR) Hi With an 600d, by far the noisiest channel is the B. The main advantage of splitting the channels is that you don't have to use B at all. G carries the same colour data as the B, but is much cleaner. That's with our UHC filter. I b...

Re: ngc6995

Hi JTOL From where did you load the colour channels? Our UHC filter is very similar to your l-enhance. For this example we split the rgb channels into separate files whilst still in Siril, our preferred calibration and stacking app. With the predominant magenta, could it be you mixed up the channels...

Hi
Lovely shot.
Judging by Google Image, I think any colour scheme is acceptable.
Cheers,

Re: ngc6995

I struggle a bit with color
Hi and thanks for your reply.
A Google image search throws up myriad colour palettes so I don't think there's any right and wrong, especially with the recent introduction of narrow band filters. Hubble has a lot to answer for!
Cheers
