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.

I had a play last night at a mosaic. Got data for 3 panels 1 of which I took different calibration frames for due to change on camera rotation. How would I stitch this lot together given they are not all using same calibration frames? New to trying mosaics.

For a mosaic, personally I would work on the panels first. So loading in all data for panel 1 and processing that to completion, nicely corrected etc. Then panel 2 and 3. After that, reload APP (or clear the data) and load the panels in as lights, set APP up for mosaic integration and integrate the panels.

I was using the extreme filter so usually split the bands and combine again. So do that for every panel. Once complete. Mosaic them together and then finish final touches once all combined?

Yes, I would try that. There are more ways, but this way (and with not too many panels), it keeps the workflow a bit simpler and clearer. I would do light pollution correction on the panels first as well and then, when required, in the combined mosaic.

Thanks. I've had APP a while but just starting to use use it more moving from DSS. Really liking it but lots to learn.

@vincent-mod With this workflow of doing one panel at a time, how would you look to correct if when you did panel 1 by it self, and then panel 2 by itself, then combined then, you had completely different colors? Example; I have over 60GB on Andromeda but when I stack the panels by themselves, one panel the galaxy is more blue in color, but then the other panel it's more purple in color so when you put them together in a 3rd run (1st is panel one, 2nd panel two, 3rd build mosaic), your galaxy literally is two separate colors on either side of the core. When I try to do mosaic mode out of the gates, it so far has been running for 16 hours and still on Register with 50kb fits files and 1005 of them. Thanks.

Ah well, I usually make my panels nicely calibrated, light pollution corrected and star color calibrated. When I'm happy with that I save them and then use it in the mosaic. It's not required, but for me it tends to make correction on the mosaic a bit easier I notice.

ps. star color calibration only works well with broadband data (so not narrowband).
