15 frames is part of the problem. Not great for full rejection (of the faint part).However, you can do a selective rejection.Many ways to do it. If you provide me the 15 registered frames I can show you. Here are the steps (for one method): 1. Use T…

Francois, There are many things to explain. 1. This is a single satellite trail. If you have more than 15-20 frames it will reject 100% completely. What are your rejection settings? Winsorized Sigma Clipping of 2.2 should do the job. 2. Satellites r…

Yes, the issue is the blending method. What method did you use?Overlay? Average? -the Blockhead
-
These sigma units are with respect to the median (filtered) of the image (the master dark).So the farther you are away (bigger sigma) the FEWER pixels will be tagged as being hot. And the smaller the sigma (close to the noise floor) the MORE pixels …

Oh...I just looked into it...The WBPP method is *completely different* .I will need to make a little video to explain it! -the Blockhead

Craig, I am not certain, I just tried today to get the latest version- but the server does not appear to be working (for me). However, unless the Universe has changed and I am in bizarro world... Smaller sigma values are MORE aggressive. A sigma val…

You need to show me a screen shot of the issue (point at it..circle it..).If it is a black line- it means you need to trim the images more. You trimmed? If the issue is a discontinuity (meaning the star shapes and stuff show the seam)- then this is …

LOL... well, I believe you...but I cannot see it easily. 1. What method did you use to construct it?2. If you used PhotometricMosaic, there are several ways to improve the result. -the Blockhead

The placeholder is already there with respect to Dual band content.-the Blockhead

I usually crop images towards the end of processing. The reason is because if I want to incorporate other images from the data set- they will be dissimilar in size and I will need to take time to crop them as well.There are a few processing where ed…

This is the issue with narrowband. There are to many ways to do it. Many different combinations of data and techniques. However, I do address part of the question in my latest videos. I demonstrate the way to generate colored stars with NB data...wh…

Sorry...this is a question for the PI forum. But if you like more words... ChatGPT says: The "Unable to locate entry point" error typically occurs when an application, like PixInsight, tries to access a function or resource in a dynamic link library…

Hi Zak, Since this will be "FastTrack", it will include the videos I have posted. I still have a few more I think to do concerning Dual Band considerations- however, I consider the work I have now done to date to be 90% there. If you think there are…

OK... but again, just so you understand where I am coming from. The origin of the image at top-left or bottom-left is the issue I was making certain was not in play. This has only to do with how the image is read... nothing about the coordinates of …
-
Well, a 180 degree rotation should not affect registration. You are correct.The issue I was concerned about is having different origin axis in the image (which would flip or mirror the image...this is not a rotation). It could be a data quality issu…
-
Inverted or flipped? (mirrored)Are you certain this isn't an origin issue? Were the images in the same orientation prior to any processing? The flipped image I am guessing is the key here. -the Blockhead

OK! Indeed, this appears to have happened in June while I was on vacation.Nice... now Auto is available.Thanks!-the Blockhead
-
Can you show me a screenshot of what you are seeing?Thanks,-the Blockhead
-
No. I am only demonstrating in this way to avoid being far out in terms of signal strength (and having to stretch the images to bring them closer). It makes it harder to explain. -the Blockhead

I favor HDRMT. I think it is easier and quicker to get to where I want to go. I am a bit of an expert/specialist in it though. It is a very sensitive tool. Ever used a coping saw? I couldn't cut with that to make moudling come together if my life de…
