On another note... If you use the GAME script... you can write zeros directly to the image. This is one of the things I ask Harmut to implement in his script. -the Blockhead

Hi Chris, At this moment...I have quite a few things on the stove top cooking (as you probably know). I need to finish these items first. I am hoping to create more videos this week. Concerning Pixel Math- read this forum entry that answers your …

HI Ray, I am not certain I understand.You would want to calibrate (and debayer) the images from each set either all at once (or separately). Then you pick at single reference frame from one of the sets (say from the 2021 set) and align *all* images …

No... This is in your data... somewhere. It could be in a single raw frame or something in your calibration data. WBPP cannot manufacture this. -the Blockhead

Wow...that is really nice to hear!Thanks Alan.-the Blockhead

PixInsight only cares about the number of pixels (dimensions) and the number of channels (color layers) of an image.These are the geometries it "worries" about. When you crop and save the image- the header will indeed be updated if you change these…

NICE!!

This is Adam... lol .In DynamicCrop you can specify the image size by typing in the number. Then you would make an image container from the process instance. You are doing this before you register your images. You do not need to crop to match pixels…

This isn't an area I know about really.My understanding (which could be wrong without doing research) is that the overscan pixels are simply reserved pixels that are generally used to measure sensor characteristics (like bias level). So... If you li…

Yes, culling bad frames by stellar morphology is certainly valid. -the Blockhead

Darn it. You are right! The Fundamentals version is one I did after Horizons...and then the YouTube version (even shorter). I do think I got better with practice. I added this language to the video page. Thank you for pointing this out. NSG require…

Right! You do not need to restrict samples of nebulous regions. If I made a statement to the contrary I need to fix that. If there is a major difference in the gradient graph (which is a graph of differences)- then I might consider excluding. Either…

OK..that seems about right.I will be adding more hours of content soon... Is this both Fundamentals and Horizons?-the Blockhead
-
That sounds pretty high to me. lolYou might have some image files or something else mixed in there. But... I do have quite a few videos.-the Blockhead

Yes, you need to set how you want the image saved. So you can adjust with the STF (or with HistogramTransformation and the real time preview) and then make it permanent with HistogramTranformation.... then save. -the Blockhead

No... I do remember that slip up. There isn't an automatic find another catalog at failure. So the default with local catalogs is APASS10 and it will use it everytime unless the automatic is turned off and APASS9 is forced. This would seem like the …
-
Yes...there are "special moves" because of the nature of the image. You did save your image- no special moves...but if you want to save your image AND get a permanently stretched version as you want it... then you have to do the special moves. The s…
-
The answer to this question is covered in Fundamentals.However, I did release the older video on YouTube sometime ago. You need to create a permanently stretched (non-linear) image. You likely saved the linear file. Please see: There are three vid…

Paul, My videos and content are geared towards understanding astronomical image processing. They are not necessarily goal orientated in terms of "what to do next." You obviously have particular preferences, and by understanding the concepts of image…
