Hi all,

This tutorial demonstrates the new comet registration functionality introduced in Astro Pixel Processor 1.083-beta1.

The next beta/stable release will also include special comet integration modes and probably also a special startrail outlier rejection filter.

Cheers,

Mabula

My first attempt with the new comet routine in version 1.083 Beta.
I followed the tutorial and it worked exactly as presented. THANKS!!!!!

Video is good, but program not do it right... I tried on four of my comets, some went through well, others worse because of the fuzzy core of the comet, I had to confirm the comet’s position several times during registration.

However, I had the most problems with the comet, which I recorded with the tracking method on the comet itself. The program completely failed. I ask the author not to do registration only on a comet (no stars) or otherwise that it is possible to register only on one star-comet.

I can send you a 16 light+22 darks - recorded with the tracking method on the comet itself.... the star are not dots but small lines for testing.

That might mean your data has an issue as it seems to work on a lot of data now. Can you share a screenshot of 1 light frame?

You don't understand ... tracking a comet just creates that kind of image ! I stak in program ''Fitswork'' only on comet - one star.

 APP does not work on such images... yet ?!

At the moment it needs to be able to register on stars yes, plus this is a beta version where we only need to know if comet stacking works on most data sets. Having star trails won't work (yet).

A new version is close and will have some nice added functionality. 🙂

What processing method/steps would you recommend when bright stars intersect comet's coma or tail?

Ideally it would be nice to separate star field and nebulosity/dust clouds from pixels representing the coma and tail of the comet so they can be stacked separately and recombined later, and having the comet pixels on black background. That will keep pinpoint stars and nebulosity sharp and comet will be sharp too.

I mean removing star trails is nice when you don't have anything else in the background, but often there are dust clouds and galaxies etc in the background and as the result of stacking images registered on comet they all get smeared.

To improve rejection of stars with my slow-moving comet I tried stacking 3 sets of every 3d frame in sequence, but the result seems to be the opposite - brighter star trails... I'm using kappa 8.0-1.1

Yes, that should be possible in the next version actually as far as I understood.

Unfortunately it is still not clear when the next version will be made available. Sorry for the delay.

@mseningmail-com Yes, this one is taking more time. This is also due to Mabula moving to his own office etc. He is very far with it though and I really think it's pretty imminent now. We asked him for an update on it.

Every day I click open the forum looking for the new release like a kid jumping out of bed on Xmas morning, but no, maybe tomorrow 😀

Yeah we know, we can't push it more than we already do. We asked Mabula about the status and hope to hear back from him very soon, this usually means he's working like crazy on it though. 😉
