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.

Star shape and quality metrics aren't adjusted for different pixel size

When combining images from different scopes, the images need to be combined with some magnification adjustments to match different scope focal lenghts. I think this also requires the star shape and quality metrics to be adjusted accordingly.

Hi Astrogee,

You are totally right, APP is actually doing this and have been doing this for several years already.

After 4) Register, you will get adjusted star size/shape and quality metrics, because APP then knows the relative magnifications. 

For instance, Star FWHM min, max (abd -- rel)

the abs is the absolute value found in pixels after star analysis. 

the rel is the relative valye found in pixels after the correction found by registering the images. 

Is this not working as expected?

This is what I get with 2.0.0-beta45, processing 15 subs, 3 subs per optical setup, so 5 different telescopes + cameras:

After star analysis:

5 optical setups after star analysis

After registration:

5 optical setups after registration

You see that even the star density appears because it is a measure of the star count per area sky. Notice the difference in the abs and rel values for star FWHM and shape. Also notice that the quality metric is changed after registration to reflect the relative focal lengths.

Please let me know if this makes sense or not,

Mabula

Ah I see! I didn't know what the relative measurement was for but its clear now 😀 Thanks!
