Yes! That would be great.If the result is clean for you... it would be a cool example. -adam

Your data might be an excellent example for me to demonstrate this...

Max, If you used the Clone Stamp tool... unfortunately it will not write pure zeros and this is what happens. There are two solutions. 1. On the images that you already black on... you need to force the values that are near black to be black ("0"). …

Hi Dave, The short part of the story- if your master flat has no information - the problem has something to do with the calibration of the flat. This means there is an over-subtraction. There are so many ways to do this! 1. There is something wrong …

Yes. It is non-intuitive.You need to start playing the video. As soon as it starts playing... *then* you can right click. It will give you the option to save the video. -the Blockhead

Jeff, if you recall I created a 'smoothed" - but it contained the local sky color information. If you do not keep enough of that information- you will indeed have a color mismatch. Remember, screen blending means that if you make anything black in a…

Yes. "Quirks" is putting it kindly in my opinion. -the Blockhead

I purchased a Tiffen Fog Filter. Took me forever to figure out what Akira et al used... finally found some mentions of it.-adam

Happy Thanksgiving!!-the Blockhead

John, You will certainly find people who will answer your above question with a definite opinion- but I will not.The answer is it depends. How much noise? What is the size of the noise/grain/blobs? Is the noise mostly in the color? Is the noise most…

Yes... It is "grouping" the exposure times based on the tolerance. So if you decrease the tolerance... viola... separated darks.-the Blockhead
-
I do think you are indeed missing something. There is a tolerance parameter for the darks. If you lower the tolerance setting by a value smaller than the difference of your darks- they will all be separate. However, this implies that the darks need …

In PixInsight the normalized images are technically transparent to the user..they are internal. But the idea is important to understand if you want to understand what PixInsight is doing..and what the parameters are for. I actually wanted Juan to ma…

Hi Fernando, Your questions have some assumptions built into them...and I would like to sort it all out. However..it would require quite a bit of typing! I am hoping to make video that answers your questions. Without any explanation this is going t…

A few topics come to mind. 1. MURE Denoise (but this might not work as well with a CMOS sensor...depends)2. MLT removal (or bias adjustment) of the 1 and or 2 layers. 3. TGVDenoise All of this things are covered as you work your way through the mat…

Hi Max, I am looking at your expression. You have an "S"... but in Pixel Math the dollar sign "$" is a special character.So you want to do ~($T) . Let me know if this is the issue. Thanks,Adam
-
Yes... you got.Good job!(this is what I demonstrate in my workflow videos)-the Blockhead
-
Hi Bryn If I understand your questions correctly... I think want you want to do is use Calibrate Only.You calibrate each data set (from each night) with their own flats and biases/darks (if necessary). Then you will use StarAligment on ALL of these …

OK...I was going to ask a follow up. Direct quotes of the errors or screen captures are very useful!Thanks,-the Blockhead

Thanks.I appears one of my directories was clobbered by the hosting company.I putting something up...but need to find better pictures.-the Blockhead
