First...there are no defaults... just need to make that clear. I would suggest integrating the images without Local Normalization to see if there is a difference.LN uses image partitions at a particular size (squares). I wonder if you are seeing en…

I am curious. What normalization method did you use?-the BLockhead

Hi Ray, Did you watch the section on NGC 3199?I did this there. Let me know if I am on track by providing these kinds of videos. -the Blockhead

That exposure tolerance is for calibration purposes... Sometimes there are small differences in exposure times (like fractions of a second) and you want to group items for calibration purposes. -the Blockhead
-
This appears to be a common request.Yes, I think I will cover this in an upcoming video.-the Blockhead

When you denoise a single color image- you will be applying the same settings to each color layer if I understand. Whereas if you do individually, it is possible to have different settings on each- and I can see how this would give odd results. For…

I think you just need to adjust the exposure tolerance setting in the post processing. Did you check out my most recent video? (let me know, or I can grab a screenshot) Regarding the underscore... there are a handful of characters that are "stop" c…

I don't think masked stretch in particular is the issue. It is determining the brightness of the background- which is high- but if you used any stretch (AutoSTF/HistogramTransformation, Curves) you would see the same basic result. It appears as if t…

Thanks Roger!Yes 16 videos..but just breaking things up to keep them shorter. I tend to go long...-the Blockhead

Mike Selby provided both 900 second dark frames and 1200 second dark frames. So all of the data files are being used and calibrated for the OIII and the SII (please watch the WBPP section). Then later all of the files (both the 900 second and 1200 s…

HI Brent, Sorry..I am a bit confused. I used all of the data provided. The H-alpha images were all 900 sec. The OIII and SI were all 1200sec. There are no 1200sec H-alpha. Please ask again so I better understand.Thanks,-the Blockhead

I think this is a longer term thing to compare the two methods and determine realms of applicability. Previously it was demonstrably that the algorithms being used in imageIntegration were failing spectacularly. Now this are improvements...so more a…

The spike would definitely lead back to the originating star..but that star could be several fields of view away if it is bright enough. It looks like I forgot to attach the image. But there are a handful of 6th and 7th magnitude stars near by... an…

HI Benoit, This is likely due to a very bright star outside of your field of view. It is linked to a star... even though it is not in the field..the diffraction from the star will be. There isn't anything in particular you can do about this... it is…

It is now in part of the lights group attributes. You can now apply different cosmetic correction templates on a per group basis. This adds extra functionality. -the Blockhead

Bill, I hope you are going through my FastTrack training sections... These sections will show you what to look for when you have an error like this (the approach I teach you). For example, I explain that one of the important things to do when encoun…

Bill, Cosmetic Correction has been relocated to the Calibration Settings of the Lights Group in the Calibration Panel. (Each word I wrote in the previous sentence is significant.). I suspect this will work just fine. I am waiting on Roberto Sartori'…

Hi Christian, I do think I offer a potential path forward in my work on NGC 3614: https://www.adamblockstudios.com/categories/ngc-3614-discovery I demonstrated how I went about trying to bring up the very faint tidal tails (that I discovered). This…

Thank you again for letting me use your image to make a video showing the various issues.-the Blockhead

No, I did not know about this.. I have just started doing NB imaging. My images are TERRBILE right now.LOL. So, this script you show will mix in a straight linear fashion in the way I show with PixelMath by putting a multiplier by the image (the per…
