UPDATE FROM MABULA

I have had a very rough 2 months unfortunately health wise. I was struck 3x in a row with bacterial infections. The second infection occurred  after a routine hospital checkup and I became very sick. I had to rest and take a lot of antibiotics. Once I was recovering and restarting work 1 month ago, I again became sick. The infection was not yet gone, so even more antibiotics and rest was needed. Needless to say, it took a lot of my energy and I needed a lot of rest.

 

Finally, the infection is really gone and my energy is coming back step-by-step now and I have started work again. I am terribly sorry to have kept you waiting for support. I will address all outstanding questions and e-mails step-by step and will be on the forum daily from today.

 

APP 2.0.0-beta47 will come soon as well, a lot of work was already completed before I became very ill, so the release is also nearly ready for you. Beta47 will be much faster actually. Many workflows will be more than 2x faster, mosaics can even be 10x faster than before because registration really received a major boost... all compared to beta46.  Before I release it, I will make sure that everything is working properly and then I will release it.

Hi,

 

I have problems during comet processing to select the nucleus of comet C/2017 K2 (PANSTARRS) I captured last night. When clicking on the nucleus the cross is jumping to the next star.  Is there a way to adjust the sensitivity of the process? I'm using Version 1.083-beta2.

See attached screenshot

 

Best

Mmm, looking at the amount of noise it might be that APP is not able to detect a proper nucleus amongst it. We did notify Mabula as well.

Hi Wolf @airwolf599,

Can you upload your comet data so I can test it?

Please upload it here: https://upload.astropixelprocessor.com/

username and password: upload

Please make a folder with your name and let me know once uploaded then I will test it a.s.a.p. 😉

@mabula-admin hello, is there a solution for this problem or a work around? I have the same issue. But only with some frames.

Not for this specific issue as it needs extra programming to hopefully get that to work on tricky data. If you upload your data of the frames that fail, Mabula can test on that.

I made a folder on our server called "comet-id-problems" in which you can put the frames.

Go to https://upload.astropixelprocessor.com and for the username and password, use: upload

I used the 1.083-beta2 to test this comet mode.  The comet is 67P and the images were guided on the stars with subs of 120s (because JPL changed its Horizons interface and I could not activate comet tracking).  The comet nucleus showed as a short trail.  During the APP registration process I had to re-click on the comet a few times and sometimes APP selected a point just next to the comet trail.  But in the end the result was acceptable.  I have uploaded these files for APP testing.

Maybe it would be better if the user would be able to click on the nucleus in each image instead of letting APP trying to do this in the image sequence? (MaximDL works in this manner, the user clicks on the nucleus in each image, the program selects the brightest part at this position).

Thanks Geert, yes that may be interesting to include, however I think the algorithm should be able to distinguish this unless the nucleus is very faint. Thanks for uploading, I'll pass this on to Mabula!

Hi Geert @geertvdbulcke,

I have tested your 67P data in the current code for the stable 1.083 release and all works well. Since the comet is not guided well, you still need to select the comet in some of the frames, but each time the comet nucleus is detected properly, also when you click not directly on the comet.

The current code has been further refined and improved from the 1.083-beta2 code for the comet nucleus detection.

Comet detected properly in all frames
Comet detected properly in all frames 2

Thanks Mabula.  When I ran the image set, on one of the images the crosshair did not center on the comet but just below and to the right of it.  But the result afterwards looked OK.

Understood, but the above is beta 3, not released just yet. 😉 So it's fixed.

Hi Geert @geertvdbulcke,

Yes I understood, but now in the current code the crosshair works correctly on all the frames 😉 as well.
