There appear to be someissues here. First there looks like there is walking noise. Are you dithering your data? second, I am surprised at the level of noise. How many images did you acquire in each set of data? (I would guess less than 20.) Next, th…

The binning isn't matching.Your bias shows a binning of "1" ...Your flats show no binning. So, is there a binning value in your headers for your flats? Also, for the sake of diagnostics... you remove your keywords (it isn't clear to me they are nece…

Assuming the data you have downloaded is already calibrated, your integer sample idea is just fine. I did demonstrate this somewhere... The difference between integer resample and general resample is that the general will interpolate pixel values- …

OK. Matching darks do take precedence over biases. So if you have a dark that matches.. this would occur- but this doesn't explain things in your case either. What you are describing is an instance where something is not longer matching. Either the…

I think I know the issue...And I JUST made the video about it!!amazing...Give me a moment and let me upload...please watch and tell me if this answers the question.If not.. you will need to provide screenshots of WBPP (use the Diagnostics button). h…

There are a couple of places.However, the latest and easiest method is to use the Substitute script that was written for me!See:https://www.adamblockstudios.com/articles/substitution-script The "manual" method demonstrated with Pixel Math (my origi…

Yes... but this is the same as black clip thresholding with NB ColourMapper (or any screening method).You would not need to make a separate mask. I am assuming you want to color each channel... this is precisely what NB ColourMapper can do for you. …

So I talked with Mike... I stand corrected. Please refer to Mike's description of things as a most accurate reference.Thanks! -the Blockhead

Since this is a Sony sensor with a CFA...the default settings (Sony sensor, QE = 1) is what you need. So there isn't anything more to do I think.-the Blockhead

Hi Richard, The information you are looking for is in my Horizons collection of videos. This is where all of the narrowband processing can be found.See: https://www.adamblockstudios.com/categories/Pixinsight_Horizons I am continually adding processi…

Mike... just to be complete- Russ is doing what I am saying when he outputs his stars-only image.

Ron, You are mixing things here Ron. When SXT removes a star from one image... what is it doing? It takes the "star" (some values) and creates a second image of the star. This star that was removed has the TOTAL light (starlight plus background). Wh…

No... screen/unscreen is multiplicative in both directions. I did actually explain how it works in a the video below. This deals with star reduction.. but it uses the screen math... so I explained it. Have you watched this? I think you will find i…

You will note this comes with a big price tag...but apparently I buy computers only every 4-5 years. lol-the Blockhead

This is the Corsair Vengeance.I purchased the pre-built version, so I didn't do anything special.I did need to decide which chip... and this is the Intel version.Processor 13th Gen Intel(R) Core(TM) i9-13900K, 3000 Mhz, 24 Core(s), 32 Logical Proces…

Numbers are numbers. They can indeed be small and not DISPLAY correctly (quantized)... the VALUES in the linear data (32-bit) are not quantized however. In addition, good integrated images (enough collected photons) do have sky values (backgrounds).…

Uggh... that is not something that is easily handled on bright stars. The ST10XME used microlenses...I used this camera back in 2006-2010 I believe.-The Blockhead

This is microlensing reflections. That is what it looks like to me. Does your sensor have microlenses?There isn't much you can do if from the sensor.-the Blockhead

The beta version is now available to all members of this site (and viewers at TAIC). You can get this beta version from here: https://www.cosmicphotons.com/pi-scripts/nbcolourmapperTAICBeta/ Remember, do not follow the link. Copy and paste it into …

Yep! This is an early release of the video in anticipation of the TAIC (The AstroImaging Channel) presentation will give on Sunday night. During the presentation, the beta repository will be made available. Or better yet, the beta will be made off…
