OK. I believe the 2x2 on-chip (acquisition) binning was an error. It really does give you suboptimal results for an OSC (color filter array/bayer pattern). I am happy to be corrected on this... but a CFA is just not binned in general. You end up mix…

I am currently producing videos on NB processing. You probably will not be surprised to learn my approach is different.I am waiting on publishing them... because of a development which I hope people will like. -the Blockhead

Hi Matt, I looked at some of your files.I am a bit confused...so I need to follow up.It says you binned the data 2x2... but this is a color camera?Please let me know..Thanks,-the Blockhead

HI, Can you provide your linear L and RGB images as well as your best attempt at the LRGB finally stretched version you came up with? -the Blockhead

Thanks Matt.Can you please describe your workflow in detail for this data?Thanks,-the Blockhead

Hi Gary, Actually.. the video you want to see are the ones in Stretch Academy.This one in particular!https://www.adamblockstudios.com/articles/stf-utilization I will add these videos to the STF section so that people can find them. -the Blockhead

Hi Gary, OK..I grabbed the file. I do not see an issue?There are no zero values. Everything looks good. Nothing Red shows up, the statistics look fine.The STF looks fine. I am able to zoom into the STF and manipulate the black point and midtones val…

Can you make the image you are talking about available to me?-the Blockhead
-
Well..I do have a list on my site that links to the YouTube videos.I think it is current...-the Blockhead

Correct.. you do not want to do that!Did you watch my video on my working with the FomalHaut data on YouTube?-the Blockhead

I believe my comment was with respect to the histogram as viewed in the logarithmic view. I think this is the part you may be missing? The way to think about it from a linear histogram is an S-shaped centered at a particular tonal value. This will …

Yes, I demonstrate using a synthetic luminance in the latest video I published (the Telescope Live Mosaic of iC 4812 in Horizons). I agree that LRGB in the past took advantage of binning the color data in order to save time. The loss of resolution …

In the File Format explorer for FITS you can change the method that it loads FITs files so that it loads it by range.-the Blockhead

Hi Gary, I do not have the ability to dive in at the moment..but, I will say that the JWST data I worked with when I processed the Fomalhaut debris disk... had an arbritrary range of values (including negative values). This is normal for their data.…

Thank you for sharing your image.I looked at the TIF file. My gut says this is probably pretty good considering this is only 2+ hours with very short exposures. I am assuming this is OSC data? One of the things that has been suggested for me to do.…

I think it is also fixed in the latest version released yesterday. I have not downloaded it yet.-the Blockhead

In this case you do not need to install them. You can literally overwrite all of the scripts you downloaded from that folder to your directory. The directory on my Windows machine is this one: C:\Program Files\PixInsight\src\scripts\AdP It worked f…

This is an excellent case of needing to create a video to record what you are doing. What you are experiencing is quite dramatic and I would really love to see an explanation. -the Blockhead

Well... I have to say the MureDenoise is pretty much a thing of the past with Russ Croman's NoiseExterminator. I mean... it isn't even close and these other things are arguably obviated. Follow this link if you are interested:NoiseXTerminator -the B…

Yes. That is the idea... save lots of time. The justification is that there are so many frames that much of this averages out. -the Blockhead
