In the new version (which you can take a sneak peek at, see my WBPP tutorials on my site), this has already been address with regards to the Status field in particular. It was moved over to the left... -the Blockhead

If you had matched darks, did you turn off optimization?

Paul... another thing... and this one is kinda lame...I processed your M101 data...which is what you have linked above. And it works perfectly ... no gradients... no problems FastTrack is in good standing.However... you image above is a globular clu…

Paul, Was it dark when you took your darks. Was it daytime..in a lighted room... a computer monitor nearby? -the Blockhead
-
Just to follow up... is this your data?(looks like it is from Deep Sky West)This was a 300 second exposure that was calibrated with an 1800sec exposure.This strengthens my argument. There would be a potential over subtraction of the dark current an…

I am not certain why the weighting would matter. Your data is not optimal- there is oversubtraction by what appear to be hot pixels. As I mentioned, this is due to a bad dark, old dark, or in correct calibration configuration.(just because a process…

This looks like a mis-matched dark frame or a bad dark frame subtraction to me. (You didn't try to optimize did you?)I colored all of the zeros red in your image. It looks like an over subtraction of a dark frame.This would agree with the idea that …

You can extract the lightness (luminance) from a color image. I circle the icon (one way) in the attached picture... -the Blockhead

OK. Good observations so far.When you take your darks..... *is it dark?* Also, integrated dark frames should be grayscale images. It doesn't make sense to see a color image of a dark frame (at least not in PixInsight). OK...if you make your data ava…

You will have to put it on a cloud drive somewhere for me to download.

Can you make this image available for inspection?-the Blockhead
-
Ah... the dark background!Something is being black-clipped during calibration.An oversubtraction. Are there actually zeros in your dark image?This sounds like a calibration issue! -the Blockhead

Looks like you got some answers! https://pixinsight.com/forum/index.php?threads/fitsheader-query.16448/ I think I was on the right track...-the Blockhead

Joseph, Likely the images have not been aligned. You need to employ your FastTrack Training tool kit! 1. Blink the registered data... is it really aligned?2. Could the reason it is not aligned be because of hot pixels? (Did you use Cosmetic Correcti…

But... with regards to WBPP... I am making certain that it clearly communicates what is going on... effectively teaching image calibration. So I think there is a little educational content now... that is consistent and aligned with best practices. …

Hi Roger, I have not read the book...but it interests me. Thank you for the suggestion.One of the reasons I highlight the deeper-processing line of reasoning is somewhat utilitarian in that I am certainly trying to set myself apart from other superf…

Grant, The funny thing... just yesterday I received a note asking... do you have any mono (LRGB) imagery videos...all I see you do is OSC? So I have been pushing the CMOS OSC so hard that now people do not think I do LRGB. Can't win. Anyway, first a…

No...I don't. This isn't something that is commonly dealt with. I will put it on the list.-the Blockhead

Hi John, You can always see my "final" versions on my website adamblockphotos.com. For example GUM 15 is here:https://www.adamblockphotos.com/gum-15.html Thanks,-the Blockhead

Yeah...my suggestion is to start from raw data and run everything through WBPP.This will ensure everything is consistent. Then, if you want, you can also run the data manually...the answers will be identical if the configuration is identical. There …
