You have a corrector lens correct?-the Blockhead
-
Hmmm... I have that somewhere... probably in a Pixel Math video. It is easy. 1. Open one of your dark frames (or light frames)2. Identify the columns you want to correct or map.3. Using pixel math create black lines on a white image. An expression f…

Didn't you answer your own question?-the Blockhead

This does not have anything to do with SPCC.There shows there is an alignment issue with your data and you are seeing the results of rejection due to misalignment. You need to check your registered frames and see what happened. -the Blockhead

A couple of points.1. If you have many frames and the dithering is good- it might not be an issue. But it depends.2. You are probably thinking of using Defect Map. Indeed, this is a pretty strong solution especially if he columns really do go across…

Hi Phil, In terms of the subsection of Stretch Academy... you would start at the top and work your way down the page. Not everything requires the previous section- so skipping around is OK. However, the first concept sections are the ones I think a…

No, not in an easy single step way.I tell you what...I bet I can make a script to do this. It should be pretty easy.-the Blockhead
-
Tom, The real point is that there IS NOT a simple single workflow. The fact you attempted to do the same steps I did on your data is somewhat missing the point. NB processing is not a recipe. No way. Your comment is exactly why I always avoided maki…

I think you mixing a few ideas. 1. Yes, the behavior of NXT may have changed over time.2. The use of MLT is now pretty much an obviated method considering tools like NXT and others that are available now. I honestly don't know what to do with videos…

Again, that cannot be correct. Note that one of the slopes is negative. Ignore what it says in the header or what you think it should be... only one of the combinations is the correct one. You need to try all of them.Indeed the roworder and mirrorin…

When you stretch your image (using HT)... is the black level set to zero?It just seems like you are clipping when you stretch the image. Your shadows show a non-zero value in HT. 0.01706864 .Why did you choose this instead of zero? (I am assuming t…

I am not convinced your debayer pattern is correct for the M92 data. Is it? Regarding the FastTrack images- did you do any other extra processing before doing SPCC? (anything I did not demonstrate in my video) The more blue you see in your image...I…

Yes sorry, I should be precise. The Blanshan method I cover in my content. I didn't catch the reference to the other methods of the script since I haven't pursued these other ways. -the Blockhead
-
The images are not aligned obviously. (Good job for zooming in to discover this). You need to blink your registered data and make certain all of the files are aligned with respect to one another. Presumably you used "Auto" for the registration meth…
-
Yes, I think there is a logical explanation.It all has to do with the starting pixel. If the image has been adjusted in anyway the bayer pattern is shifted and does not start with the correct (Red) pixel at the top left of the image. Some software …

HI Melvin, I cover star reduction in a number of places. In addition, (and you did not mention), I came up with an independent way to do star reduction as well and a script we made for it. The Bill Blanshan method is not really star reduction per s…
-
Yes, more analysis... but I am of the mind star removal (or lack thereof).-the Blockhead
-
Well... it looks like the star removal is the culprit. Those are either faint stars or incompletely removed stars right? -the Blockhead
-
Not really.If the correlations are the issue... you *can* do something...I am not saying it is great.You can use the noise generator to *add* a tiny bit of noise and randomize the pattern a bit. You would need to do this at the lowest brightness lev…
