Correct. Juan addresses this. WBPP is not loading calculated values... all of the calculated stuff only applies to images loaded in PI. When WBPP opens images... it is not "loading them" like in the program. It is opening them from the disk as is. S…

Yeah, I am stuck on your dither. If you indeed did not have any dithering in the horizontal direction..this would definitely account for the issue. The amount of dither is perfect... but you need to randomly dither in both directions. Is one of your…

Ah! OK!!I threw that in just as a sanity check.Yeah, PI has an official compliance for scripts... but you can load any scripts you want even it is does not meet PI's compliance metrics.-the Blockhead

You are doing nothing wrong. When you get to the video on setting up the data- you will see that I end up using the biases to calibrate the flats (since I have so many more of them). So everything is OK... you can continue! -the Blockhead

Ok... so how much are you dithering between frames?-the Blockhead

Hi Matt, It is working (all of Hartmut's scripts) for me.I suspect you need to force the update of your scripts. Remember to permit any with not signatures.-the Blockhead

It does look like walking noise...but it is SO vertical. I am suspicious.You did not, by some chance, use the Linear Defect Correction in WBPP?You should not use this.-the Blockhead

Do you measure any zeros in your frame?(see my video on use of the Pedestal)-the Blockhead
-
My opinion is no. It does not make sense to get flux calibrated images before doing the other stuff we do. I address this question specifically in this video:https://www.adamblockstudios.com/articles/spcc-narrow-band-mode Did you watch it? -the Bloc…

My suggestion is to do FastTrack Training first...and then the QuickStart videos...and go from there.I have a suggested order of viewing with my "Fundamentals Path" list: https://www.adamblockstudios.com/articles/the-pixinsight-path You might be ta…

It is somewhat non-trivial and I have not seen a tutorial that touches on this subject or explains it at all.I discussed this with John Murphy some time ago as it became important for one of my own projects- NGC 1232. I combined data from *three* di…

Hi Jon, A couple of things. Please verify: 1. In WBPP you had "astrometric" checked. It seems like you did.2. When you used ChannelCombination (did you use ChannelCombination??) you need to have the box checked to Inherit the Solution. It is checked…

This ghosting is typically caused by internal reflections between the filter and the ccd window (or surface). It can also be caused by a corrector lens (or reducer) and sensor. Coming soon will be a solution to this issue that will not require Phot…

Aligning different images with DynamicAlignment is pretty trivial. I do demonstrate how to do this with a few videos (M1 Crab Nebula was one). The real issue is alignment is going to interpolate pixel values. Both the difference in image scale and …

Yes, gain and offset must match.There would be zeros in the calibrated data as I suggested. Thus, there is oversubtraction. The reason for the oversubtraction you found. It is a good lesson.-the Blockhead
-
Hi This looks like one of your raw frames and not a calibrated frame. A calibrated frame would still be in the XISF format. Can you please provide a calibrated frame?
-
Hi Les, Setting the offset on your hardware, literally your camera does not solve this particular problem. It is the inclusion of a mathematical offset which eliminates an over subtraction that can occur when the sky is very dark E. G. Narrow band …

Also uncheck "Linear Defect Correction."Do you use this.. .period. You can consider using it after everything is working and only on monochrome images. Even then, this is a special purpose option that no one should use unless they know exactly how i…

You didn't mention zeros in the data... you didn't indicate a pedestal.Can you please indicate this confirmation as well?Your Jpeg image looks like there could be zeros. From your log it really thinks there is nothing to measure in your pictures. T…

Yes, you need to calibrate the data! It appears to me you showed me integrated non-calibrated data. This is *not* the AdamBlockStudios way. LOL So, if you calibrate the data properly the walking noise will likely be less of an issue.The other issue …
