Do you have a preview associated with the image?You will need to show some screenshots of the settings and zoomed in region of the image ..perhaps at 400% - 600% .-the Blockhead

No he doesn't ... He, Ron and Peter messed up and "accidentally" used my moniker for a workshop a little while ago.They apologized to me and said going forward they would not use the name. If you know something I do not know...let me know. -the Bloc…

Yes, that is exactly right. The different settings will mean it will not calibrate well. (It does not calibrate for me either.) So you did exactly the right thing to look in the header and figure it out. Consider it an "Easter Egg" . lol Concerning …

Ok... so, you will need to organize your files.You need to make 11 images of each file type available to download. I warn you...If I figure it out... I might make a video tutorial on the issue! (with your permission( But before this- You should try …

Hmmm... I don't know. Let me think about this for a little bit before I answer... -the BLockhead

It is done.I have made the data available ...-the Blockhead

That was the direction I was leading without actually investing...something about the bias.Typically the issue (with DSLR users) is that they take biases and darks in lighted conditions (daytime)...but be done in complete darkness. There are also so…

Thanks for this Stephen.I get these kinds of questions all that time... it is hard to keep track of all of the idiosyncrasies of OSs.-the Blockhead
-
Hmmm... that is not the normal saturation issue. (Which was resolved a while ago.)I suspect that the drizzle integration isn't rejecting as well (or in the same way) . How many frames did you use? What is the value in the black dots. When you creat…

Correct... so my last reply.... -the Blockhead

Paul, I do not think your OS is changing the actual file format/name. Your computer is just trying to guess (and fail) as to what computer program to open the files with. So, I think you can ignore this. Unless you tell me differently the file will …

DLSRs are tough. They do some weird things compared to astroCCD/CMOS cameras. It seems like the calibration of the flats is causing an issue- the problem is with the flats or the bias. The part of the equation you didn't include was your bias. So..…

At the risk of upsetting the University... yeah, I would like to do this. Let me work on it.-the Blockhead

There are a number of things that can cause issues. Most of them deal with the data itself. Are you certain it is WBPP where there is an issue? Photometric Color Calibration is where plate solving happens. StarAlignment can give you issues... but it…

I hear you.Thanks,-the Blockhead

Hi Roger, Thanks for the feedback. 1. I don't think so. The values are simply so small that even if I click on them..it wouldn't make a difference. Also consider that the 2015 rendition did not use DBE...and the 2021 version looks very similar. So I…

Hank, It depends on your platescale. Try ten minutes exposures at 0.33 arcseconds per pixel and you will not be happy with unguided results. You didn't say what telescope you are using..but I am guessing your plate scale (probably with a short foca…

I don't think I have a particular video- but many videos where I do the thing.If I understand your question, you simply put the name of the image into Pixel Math... and replace whatever image you want to overwrite with this image's pixels. Generalll…

Make available 5 of your frames in each set- including the frame you chose as the reference and 5 of the frames of one set that did not align. I -the BLockhead

First, you don't want to stack do you? You want to generate just the registered files. You will need NSG to take care of the differences between images. For alignment between images that have different distortions- likely you need to use the Thin Pl…
