You can always set up a "template" (and example settings for WBPP) and save of instance of it. Next time you want to use WBPP..you would open this instance and you have all of your preferences saved.-the Blockhead

You need the NVIDIA card. Russ Croman's instructions are definitive. It is involved...but wow, the results are amazing. I can remove stars from a large image in 4 seconds. There is no downside really...you are enabling an otherwise dormant capabili…

Correct. It is just the assembly (integration) of the images does not use regular interpolation.-the Blockhead
-
Assuming you have well dithered data and 15 or more frames... Drizzle has two features. 1. Avoiding the pitfalls of interpolation artifacts that come with regular StarAlignment (registration). (Drizzle 1x1)2. Improving the quality of spatial info…

So the question is... why are you getting two different file sizes?Do the raw frames have these two different sizes?This is the source of the issue. Files need to be exactly the same number of pixels to be grouped together- there is no exception to …
-
Yes..the explanation is... DO NOT USE LINEAR DEFECT CORRECTION. This is really a special case algorithm that can, if not configured perfectly, produce the artifacts you are seeing. It simply isn't a process that works on all data- and certainly sho…

Hmm... No, it would not make a good CC frame... at least not in the way I suspect you mean.A rejection frame shows values from light (photons) that are likely to be spurious for a number of reasons. The reasons include everything from cosmic rays, t…

Hi Chris, Please follow the "FastTrack" philosophy. Start by looking at the outputted files and the log (not the summary). The philosophy you need to show what *is not* the problem. Look at the values of the calibrated images. Show they are not the …

Sorry Roger... When using Photometric Mosaic, the scaling factor that is computed should compensate for the difference in flux/signal between the cameras. So I do not think this is an issue. It is possible (as I show) to tune the scaling factor as …

Love it! LOL Thanks for showing me.(x+y)%2 is pretty elegant as a starting point... I wish I had thought of it myself!-the Blockhead
-
Hmm... not advice... but instead the solution! You indicated an issue... but did not indicate the problem so that myself or others can learn from you! Was it really necessary to revert to a previous version? Is this an issue with version or third pa…

You have two problems. Do you see that "Pelican" for the your lights refers to a value of "180s" and NOT the date?Your Light Frame has the word "Pelican" in it followed by "180s" ...this is the issue. You need your keywords to be independent and UNI…
-
Your calibration tab looks correct to me. You have custom filters that you assigned and they are being calibrated by the flats from two filters taken on two different nights. So you have unique flats on two nights... which are calibrating the D1 fil…

There is a new parameter in PixInsight that controls the detection of structures and their sizes as it relates to stars. You may need to adjust this parameter or others. In StarAlignment there is the Detection Scales parameter which you can increase…
-
You did not mention it... so did you use cosmetic correction?Are your stars larger than 5 pixels in size? -the Blockhead
-
Hmm... I am not certain. I am not seeing an reports of issues of PI crashing or anything.If you are not using the latest version of PixInsight there is a chance the fact this script has a signature file is an issue. (use the latest version of PI ! )…
-
Yes..correct. Giving permission to exclude PixInsight (or file types) from being scanned.-the BLockhead
-
You should make certain you have taken care of the exclusion/permissions regarding PixInsight file types (did you?). Not doing so will definitely 100% make things go very slow. EZsuite and Starnet were not wiped out- this is a third party issue. I …

Whoah... hang on there partner!We have to be very careful about language here! Bias frames are zero second (or insignificant) exposures. What I think you are confused about is that I say that for normal CMOS and CCD cameras you can use a bias to lik…

Yes, you would lose the diffraction spikes (and I think you should!).However, if you want to keep the diffraction spike STARS... the whole thing the star and the spikes. 1. Integrate everything and lose the spikes. This is the full data.2. Integrate…
