Thanks for following up!-the Blockhead

Subtraction is tricky! You need to pay attention to two parts: 1. You need need to make sure you understand the reference!! It does not appear you have done this in your picture. Please review the section that I explain... The starless comet (operan…

I acquired Comet Tracked data of A3 last night...So... more content on the way. I am going as fast as I can.-the Blockhead
-
In addition...I am attempting to get better data with A3. So hopefully soon...-the Blockhead

Ah... uncalibrated flats were NOT be helpful.good luck.-the Blockhead

Do you know how many variations I have in CometAcademy?? LOLApparently not enough! My concern is that people find it overwhelming... so that sometimes frustrates people... but then they are also frustrated if they cannot find the exact demonstratio…

1. No. If you keep the project file and folder in a child folder (same relationship as now)... then I believe everything is OK.2. Yes. If you need to do more you can temporarily copy to the SSD ..and then back to HDD.3. Scripts are dynamically downl…

Ok. If you are not combining the original subexposures... (this would be better to give the proper normalization and weighting)... then sure you would just combine with the simple expression of ImageA*q + ImageB* (1-q) q is the fractional amount (pe…

I am working on itI have it mostly done...I hope to complete it on Monday. -the Blockhead

It just seems like the values are tiny. The stretch is so large that there is a quantization of the data.That is the reason your gradient remove doesn't work... not one of the methods would handle this situation.I don't understand how you achieve th…
-
Yeah... something does not seem right about the image itself.Maybe the clouds... but the image seems crushed already. There is a very large gradient that I would have thought flat fielding would have helped with. I think you need to look back at the…

Yes, you were trying to open them in PixInsight or something. They are not image files...and cannot be opened in that way. They are loaded into ImageIntegration.-the Blockhead

Hi Craig, I think there is a misunderstanding. Can you show me a screenshot of the issue?LN files are indeed small. They are loaded into the ImageIntegration (there is a button). -the Blockhead

Hi Marc, Sorry... I am not certain I understand. I do not sell "licenses" . Are you talking licenses to Russ Croman's software? If you are talking about BlurXTerminator- yes, if you do not have enough signal it will not sharpen. This is good since y…

Given a large number of frames FBPP can be a great timesavings solution. You can't do anything harmful by not using is..but it can cut down on some time if used. Criteria:1. Many Frames2. Frames that are most free of *changing* gradients3. Frames a…

LOL...just check here.As you know know..I do briefly cover this in Comet Academy. Once A3 is high enough..I will hopefully do a better example. -the Blockhead
-
Well... as of last night you need a minimum of 15 degrees in terms of field of view. If you want to get *everything* ... double this. I am putting together an image that stretches more than 20 degrees and it still isn't enough especially because of…
-
Sure... comet processing is HARD. No one seems to get this! lolThe issue is that there is a changing sky gradient in every frame. So the distribution of light on top of any flat field errors will cause this issue. 1. Flats will definitely help.2. Pr…
-
Yes, for the reasons I indicate above. When there is simply less light (especially from the sky), the error will also be less and may even be invisible. I think you will find broadband work will generally always produce the issue to some degree. -th…

The issue is the reducer. It is what is causing the circular flat field error and perhaps other issues.This is a common issue. You are supposed to be impressed I looked at the image and identified you are using a particular piece of equipment. Your …
