I need to look into the set up of this forum.I am not certain- at the moment that may be true. I will try to figure it out.-the Blockhead

ooooh.. did I guess correctly?yay!-the Blockhead

I think I know what you are talking about... but seeing an example in an image (yours or someone else's) would help. Can you provide a URL?-the Blockhead

It was...but I removed it.I made this a stand alone section under PixInsight Horizons: Techniques and Fixes. Not everyone reviews the object tutorials..so I wanted to make it a stand alone section. -the Blockhead

Yes! -the Blockhead

HI Pamela, Hmmm... I am not certain without seeing more. The two basic ways to do things are: 1. Make a collection of process icons and save the set of them as something you load to your workspace. 2. Save a project with all of the process icons alr…

Yes, definitely. ArcSinhStretch is really only one of many ways to stretch the color data.I get this question a lot... which means I think I came across as saying this is a primary method. It is a good one... but certainly not the only one. Multipl…

Hi Jeff, I recently found something you might want to try. If you take your images and use ImageSolver... and then use the AlignbyCoordinates to undistort the images... and THEN use SA to align... maybe something magical happens?It is worth an exper…

I was correct. The issue occurs during their calibration and the treatment of floating point values.I suspect this is an issue during flat fielding due to the extreme vignetting they are trying to compensate for. I would suggest you connect with the…

HI Reggie, I looked at the data. The problem isn't simple. It isn't really black cores... and they are not small. The type of artifact in the centers of stars varies across the field. Interestingly, the stars in the center do not show the artifact (…

You will need to put the files cloud server somewhere (google drive, OneDrive, DropBox..etc) for me to download. You can reach me at ngc1535@caelumobservatory.com .-the Blockhead

Hi Reggie, Could you make a handful of calibrated frames with the issue available?I will have a look at them.Thanks,-the Blockhead
-
OK. I understand. Yes, they are calibrating on their end. You should see if the black bits remain after Image Integration. I have seen them in Telescope Live data..and ignored them as they do reject out (usually). It is late now..but I bet you coul…

No..the official PixInsight Forum. https://pixinsight.com/forum/index.phpNo... definitely do not bother to measure for each channel- my concern would only be valid for a filter wheel situation. Unfortunately... this is probably pointing towards opti…

Reggie, This does not seem like an easy way to go about doing things. The manual measurement of position coupled with a non-algorithmic guess at substitute value I think are going to lead to less than desirable results and or at east the ratio of re…

Hi Jeff, Yeah, I don't have an easy answer. That looks like the kind of optical distortion that I suspect is difficult to get right when you register the images. I assume you did play with turning on the distortion parameter in StarAlignment with th…

Yeah...Drizzle can cause a number of used with saturation due to the way it works. -the Blockhead
