Hi everyone SVDecon is fine on both 539 and 541 under Ubuntu 22.04 even on an old i5, 8Gb. Could the issues be os specific? Observations Decon of the stars seems harsher than 1.8. 5 iterations in 1.9 seem to give similar stars to 10 in 1.8. The starfish method of sampling is an improvement. The tran...

This, for example, greatly reduces the need for things like the Shrink module. Hi JTOL... But please don't remove 'shrink'. It has saved many an image for me! The combination of svdecon and shrink produces a far superior result to those awful star-removal algorithms which are currently fashionable ...

SV Decon no longer requires separation of samples when using built-in mask generator Hi everyone Not sure about what this means. The spiky style star mask in the new SVDecon makes it difficult to select stars for sampling. Maybe we don't need to select stars in 'Sampling'... (?) Any guidelines for ...

banding Hi Love it. Amazing detail. And patience! Assuming Siril for pre-processing... Before you register, you may want to run the sequence through banding reduction . It doesn't alter colour so AFAICT, should still qualify for opening in st as OSC without penalty. Cheers and HTH, Steve Added skyg...

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

Here is my starless m52:












Hope you liked it.
But seriously ...!

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...

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...

Hi everyone

More a bump than anything else so...
This would be especially useful when visualising the second AutoDev ROIs.

Cheers and clear skies,

[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...

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...
