Yep... that is the problem. The parlance of astrophotography... and Pixinsight in particular make this kind of thing *very* difficult. I did look into it (it is a common request)...but I cannot find an inexpensive solution. There are "easy" solution…

Yes, the "green" image looks correct. This is what an uncorrected color image (from OSC) will look like. If you display with an unlinked STF... you will likely have what you intend. Unfortunately your stars are out of focus...but that is a different…

This appears to be the part of the post processing sequence that looks at images to determine a reference for StarAlignment or weighting. This grayscale conversion is only done in memory- and does not affect the debayered images. Are your debayered…

Hi Matt, Hmm.. a couple of things... 1. PixInsight does *not* convert your OSC images to grayscale during calibration. Not if you load the images as PURE RAW (as shown in FastTrack Training). The images should be grayscale to begin with... and *then…

No... the blink window is effectively a permanently stretched image. You can't use the values you see in the viewer for blink. -the Blockhead

Gordon: I think you are going to make me have to go back and make another video. lolIs this an official update to the script (or just you editing the code on your installation)?If this is an official adjustment- I could certainly use some language/s…

Yep.. you have discovered the other thing. The full well capacity for binned images *does* completely fill the larger binned pixels and the limit of the ADC to count values is 16-bits! So you will see actual 65K counts (or bigger numbers). This is a…
-
Typically camera manufacturers set the gain so that saturation (full well of electrons) is around 40K out of the possible 65K that is possible for 16-bits. This means the cameras are slightly less than 16-bit in dynamic range. The addition of AGB su…

Hi Roger, Thank you very much for noticing this!It has been fixed...Your observation took some real thinking there... (you had to make a connection between the two).Very much appreciated.-the Blockhead

Yes... a Keyword and its Value need to be separated by a known character... I believe "-" and "_" are the obvious ones. (I can't remember if there are others). These are called "stop" characters because that say when to stop reading... -the Blockhe…

I plan more NB.Just can't produce videos fast enough...The SQUID nebula is in process. Regarding the pock marks. You can definitely use my technique that I employ in the MANUAL version of my star deemphasis. Have Starnet (or StarXTerminator) output…

This is definitely the kind of issue that a screen capture or file would help!Without seeing the artifact... I don't think we can guess... -the Blockhead

A couple of things: 1. If you intend to put the stars back after adjusting the starless image- the "pock-marks" will not be a big issue. They are really only an issue when you are just displaying a completely starless image. 2. No, I do not believe …

I actually did ask about this with regards to another issue/context. My gut says in your case, there should be a way to match and get what you want... I am thinking Binning...but I am not certain. -the Blockhead
-
So... I looked at your data- and this is a very special case. When you are looking to the Geobelt- the satellite trails run over the *same* pixels multiple times. This is why the rejection isn't working as well. And paradoxically, if you take more e…
-
If you pick 20 sub frames with lots of satellites... you can upload a subset and we can see. Sigma Thresholds will be a bit more brute force with the rejection (as I demonstrated in my video). So you can try WInsorized Sigma Clipping with 1.8 high s…

Yes, I think EGAIN is what you want. But why not calculate it yourself withy our own sensor? There is variation from camera to camera- the manufacture will only give you an average/typical. (sensors can change) I have enough videos it is hard to re…
-
Don, I do not think NSG has anything to do with the issue. With regards to the reference frame in NSG, it shouldn't matter very much which image you choose (as long as it isn't the very worst one anyway). Normalization is a image matching process an…
-
I do not think you want to put the word "Master" in the path name. You can name the Folders "Day_1" and "Day_2" . You put the flats and the lights into the corresponding folder. Your keyword would be "Day" .Is this what you mean? -the Blockhead

I haven't figure out a good way to do that.I am generating enough content, I am not convinced that people want to see an e-mail every other day? I did establish the mailChimp e-mail list- so I certainly could start that practice. Right now I post on…
