The green is correct and is a sign of a well-processed image. M42 is one of the few objects that is O-III ("doubly ionised oxygen") emission dominant. Keep doing what you're doing and call out people that doctor their images to remove the green O-III emissions! Thank you, Ivo! I thought we had disc...

I have an issue with M42 (image below from a couple of weeks ago.) It isn't visible from my location very often and when it is, it doesn't stay in view for very long (trees, houses, clouds and a northerly location). So a few short duration lights is usually all that get captured. The problem I have ...

Thanks, Dietmar, that fixed it.

I am afraid Dutch is just a bit beyond my slowly failing faculties these days!

Great to see another updated version out!

On my system (at least) the menus and messages now appear to be in Dutch:
Not sure if this is a configuration error on my machine (Win 11 pro , AMD Ryzen 9 5950, 32 Gb RAM, NVidia GTX1660) but it occurs in both GPU and non GPU versions.

OK, here we go. It centres on the technique originally described here: https://forum.startools.org/viewtopic.php?f=7&t=244 by Ivo for separating the stars from DSOs. This is also referenced in Guy's list of Special techniques Starting with the original stacked image, Optidev, Crop and then wipe. Aft...

Thanks for sharing your original data, Jeff. I have had a very quick play, using the technique I outlined in our PM exchange. I seem to have lost a lot of detail and the colour has come out differently, perhaps as a result of a rather too quick use of Wipe, but see what you think? Bode_sGalaxy blend...

Starting this thread in response to a comment by Jeff in the Special Techniques thread. Jeff wondered if there is a simpler workflow to keep the stars under control while teasing out the nebulosity, that perhaps didn't involve Starnet++? I have had a go at the posted jpeg in that thread (1st image h...

... ? @almcl , do you think that there is any special relevance of this setting for processing in ST? Well, the advice in one of Guy's tutorials was to avoid the stacking software making any changes to the data and when the check box was available it was advised to leave it unchecked. I am not sure...

Hi Dietmar I must confess, I haven't used my DSLR for astro imaging for a while now, so haven't seen any problems as all my images come direct from the ASI 2600mc as .fits files. Interesting idea about making a StarTools fork of DSS which, as you say, is lightning fast now compared to ASTAP. (It han...

For those who use Deep Sky Stacker (DSS) the latest editions (5.1.4 and on) are automatically setting the black point to 0 and there is now no option to disable this. In previous versions (eg 4.2.6) a check box was available to prevent this happening, but this has now been removed. ( Discussion on t...
