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 have noticed a bizarre thing when comparing two master flats. One was created via a Master BIAS, the other was created from Master Dark Flats, but the flats source files are the same. When loading the files up in PixInsight, the Master Flat that was BIAS corrected shows the correct number of total pixels 61171488 (9576*6388), yet the DarkFlat calibrated version shows 61171486, 2 pixels less. This is the snapshot from the Statistics for each file

MasterBias Corrected:

And MasterDarkFrame Corrected:

I have since checked all the other calibrations, and all the Flats calibrated with MasterBIAS all report 61171488, the ones calibrated with MasterDarkFlats:

L: 61171486
R: 61171485
G: 61171484
B: 61174185
Ha: 61171484
OIII: 61171484
SII: 61171484

I have also noticed that the "Maximum" value of a pixel is much lower in the MasterDarkFlats calibrated flats too.

Should this be a concern?

Regards

Simon
