Re: Color balancing

I forgot another example of l-eNhance with white stars and still prominent OIII signal. It's from this forum:

download/file.php?id=1812

Presumably processed in StarTools :-)

Re: Color balancing

Hi Ivo, thanks for having a look at the dataset! Are you sure you are using the recommended settings for DSS? The dataset seems color balanced already, while the expected background bias is missing. Not sure about every single setting in DSS, but I'm pretty sure there was no color balancing. The sta...

Re: Color balancing

That might be a good workaround and first approximation. I will try next time! Thanks! :thumbsup:

Re: Color balancing

Hi Ivo, Wipe does not color balance - it only subtracts an image-wide bias. Thanks for pointing that out. So I rather meant the intial color balance of AutoDev/FilmDev after removing gradients by Wipe. AutoDev and FIlmDev do color balancing, right? At least in the Dev module one can chose between ca...

Re: 1.7.430 alpha with new Super Structure module (Life replacement)

I have seen this before and it is caused by the GPU driver silently crashing. It should finish with 60 seconds on iGPUs. Does this help ? Does this still happen with very small datasets (< 1024x1024) as well? What specific computing resources have you got at your disposal (what does it say in the A...

Re: 1.7.430 alpha with new Super Structure module (Life replacement)

I have an issue with the new super structure module: it does not stop calculating. Even after 25+ min it does not finish its job. I tested it on the DimSmall and the Isolate preset. I've used several of the alpha versions, right now the most recent one (1.7.438), which is right now calculating the D...

Triangulum galaxy

My first try at blending narrowband data and RGB in the layer module as currently discussed in the forum.

Color balancing

Hi everybody, quite often I face the following "problem": Wipe does good job on removing gradients and finding a good enough first color balance. But most often a slight red color cast remains (maybe due to the full spectrum mod of my DSLR?). In order to get rid of this, I enter the color module. Th...
