Thanks, Adam. I will take a look at them and see how it goes and maybe also try the script to compare.
-
OK- fair enough BTW- I went to 10 years of college, so a few more won't hurt when you are ready to instruct
-
I finally figured out the problem- so my headache is gone and hair pulling has subsided. A light leak was coming in through the camera tilt plate in which one of the 3 push/pull screw sets was not tight. I doubt it was more than 0.5mm of an openin…

Wow- this hobby is starting to give me a headache! Thanks again for your help!!
-
thanks- will do- for the heck of it, I just ran manually star alignment and image integration (no flats/darks/dark flats) on the 90 red frames I will redo my darks, and dark flats and flats at night. I usually do them during the day in my observat…
-
A single raw red frame does not...... and the green, blue and lum individual frames look similar to the red. So, I am guessing there has to be something wrong with my darks or dark flats?
-
Not sure if this helps, but here is a red flat which does not show any obstruction and appears to be centered.
-
yes- the red and green look the same. I can redo my dark frames. I'd be surprised if the filters are not centering properly as when I do NB, I don't notice this and they are all on the same 7 position FW. However, I will check. Thanks

ah..ok Earlier today I tried adjusting exposure tolerance under the LIGHT tab, which is wrong. Then, when I tried doing it under the post processing but I made another error. I used 600s instead of a number greater than the difference between both…

After combining the different gains and using your calculation on the use of a pedestal when required (great video on that), I was able to get a decent image of the faint planetary nebula, PK164+31.1 (Jones-Emberson-1), from my light polluted suburb…

Thanks, Adam. My headings are consistent. I watched 2 of your videos on this topic and they are helpful, but I posted the question in haste and then jumped to my own conclusions as to how to do this instead of watching the other videos. At first,…

Version 2.3.2 I understand all NB data will not require a pedestal. What I was trying to understand is, what would be the harm in having a baseline of 100, even if it was not required, and then one could increase it if needed. However, your answer…

I think I figured it out.

Thanks, Roger. Greatly appreciate the suggestion.
-
Sorry- LOL! ok- got it- thanks again for the advice. I definitely need to collect more hours of data as I know my background would be too noisy to do this.
-
Thanks so much for the feedback and suggestions. First- I was not even aware of the color corrected HDRMT method- I just used the default settings on the tool Second- Going back and looking at the RGB and luminance linear images, I think the core i…

Adam- why do you always answer my questions with a question?.....LOL, just kidding!! OK- this is interesting as I utilized every one of those techniques in this image. For example, I used HDRMT to lessen the bright core and LHE and unsharp mask to …

Thanks for the video link. Based on this, the other information provided here, and other readings I have done in the past, including asking others who are using this camera, there really seems no benefit to 2x2 binning that I can tell other than sm…

"My guidance for CMOS data is to always capture the data with the camera binned 1x1, even if the data is significantly over sampled. Some processes (like deconvolution) even benefit from working with over sampled data. I do a resample of CMOS data…
