Hi!

If the version is still released this year, will the function be integrated here in which you can stack comet and stars together? In the video it was mentioned that this should be in the next version, but I wanted to ask for safety again if this is still up to date?

It is yes. Apologies for the delay, Mabula has also been moving etc. so it's been a very busy couple of months for him. I do expect it within weeks.

Hello Mabula & Vinvent,

I used the new comet registration feature a lot and it works fairly well for brighter comets. But I failed to register comet cores if they are dim and a brighter star is within the green square.
This is a pity, I think it would help if the dimensions of the "catching area" could be changed!

Best regards
Helmut

@helmut-dannbauerdrei-at I have passed on your request to Mabula.

@helmut-dannbauerdrei-at Mabula told me that the comet registration will work differently in APP 1.083. The green square will resize automatically accordingly to the size of the comet. He is familiar with your use case of a bright star nearby and says that that should be fixed as well.

I finally have collected some decent data on Leonard... Any update on the combined stars and comet stacking?

@tailspin45 That looks like a comet registered stack.  My understanding is that there is supposed to be a version that does a comet registered stack, then a star registered stack, and then combine them in a way that both the comet and stars are sharp, no tailing.  This is what my inquiry is about...

Hello, is there any update on the comet registration process to allow static stars and static comet in the same image, ive seen mention that this can be done in APP but im unable to work out how?

 

Thanks

Mark

It's not possible to have sharp stars and a sharp comet automatically, yet. The next release first fixes a number of issues that were still in the comet registration module: https://www.astropixelprocessor.com/community/release-information/astro-pixel-processor-1-083-preparing-next-release/

Method suggested by Adam Block involves removing stars with StarNet or StarXterminator and then you can do one star alignment in APP to get comet only image. Then you can subtract the comet from star-only subs created by StarNet to get the star field. Then combine them. The residuals after Star removal on the comet image can be removed by creating a mask for the comet and blurring or cutting to black point for everything else.

Dear APP friends - for your interest I just loaded an image of comet Leonard to Astrobin ( https://www.astrobin.com/rdckuj/). I used the comet registration in the new APP 1.083 beta3 release. I also used local area normalisation rejection to minimise star trails, but you can still see artifacts.

thanks

Warwick

@vincent-mod

I think if we can freeze images resolution not changing every time in comet stacking and star stacking of the same data set,  then we can use RGB combine tool to blend comet with star images. Is it possible?

Mmm, I don't think so at the moment. But I do know Mabula is working on getting the star-field extracted as well, so a combination would be possible in APP.

Wouldn't be a bad idea to allow plugins like StarNet++ or StarXterminator to be used instead of reinventing the wheel.
