Hi Peter, I am not certain I understand the question. The files you are downloading are no FITS files. They are specially made files that formatted to be used in PixInsight. You do not open the files directly (and your computer will have no idea wha…

I do have to agree with Jeff. You can force PixInsight to recognize these are stars...but it will be a fight for both the ImageSolver and image registration. If you want to go through the exercise of proving to yourself it is the star focus that is…

Indeed... I don't really know anything specific. I do have an idea of Russ's desires...but that is it. So I think it is fair to say Russ is still working on things...-the Blockhead

I wonder... you mention that you have two different exposure times. Are you certain you are not subtracting a 600 dark from a 300 second light frame?This would cause large negative numbers that a normal pedestal would not be able to deal with. But..…

You are going to need to identify the frames that are considered "bad" and compare with "good" ones in your calibrated data. There will be a difference and it should be visible. Remember to zoom in. -the Blockhead

No zeros in the calibrated data correct? -the Blockhead

Hi Jon, Well.. you have hit upon an important distinction. Where to go from here depends sensitively on the choices you have already made. This is a point I stress in Stretch Academy. Once you have stretched the image- if you are not entirely happy …

Did you search my site for FastIntegration? (see the attached image)Everything on YouTube is also on my site. I have a YouTube section on my site as well. https://www.adamblockstudios.com/articles/fastintegration-part-1https://www.adamblockstudios.c…

There is something you are not understanding.If you are zoomed out of your image- you have to remember that PixInsight is rendering your zoomed out image on your screen using some graphical math and interpolation. You are not losing stars or data. T…

With the number of frames you are using- you should be using FastIntegration. This really is the best solution. It can be utilized from within WBPP nowadays. It is in the PostProcessing tab.Please watch my video on FastIntegration to understand how …

Hi Donald, I have two interviews with Russ Croman on the details of this that answer your question:https://www.adamblockstudios.com/categories/Deconvolution In addition, I demonstrate the answer in a number of videos. The simple answer is that:1. If…

Sorry..I am not certain what you are doing. But I think the answer is yes... you need to leave the images 100% linear. This is a linear fit and the "refining" you mention probably messes this up. -the Blockhead

Awesome! It appears you missed the meteor itself. still...nice!-the Blockhead
-
Gary, 1. Once you move into the non-linear domain- no matter how careful you are, you will be affecting the color balance you achieved with SPCC. However this can be small if you are careful to make modest stretches and raise the color saturation. T…
-
Gary, I will answer your question. However, you have to do a little work first.You need to watch my entire video that explains what color calibration is and how SPCC is doing this- more accurately than any other tool currently available. Zero people…
-
Yes, as I mentioned you can used calibrated monitors and attempt to work in the correct color space and color profiles. It is technical and complicated. -the Blockhead
-
It so happens I show a trail like this in a video I made.(look at the top left of this video)That "cloud" after the meteor is what you may have captured.-the Blockhead
-
Wow... Well... it could be a "water" dump from some mission. But actually.. this looks like a meteor trail (left behind afterglow). It is what I first thought it was. Not certain though. We are nearing the Geminids...so maybe? -the Blockhead
-
Nothing special. Yes, curves and saturation have done the job for me. -the Blockhead

Haven't made it yet. The method does appear quite clumsy. It is still on the list- but not a priority.-the Blockhead
