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.

How to select reference frames for LNC (Local Normalization Correction) or LN (Local Normalization)

Dear Mabula,

In my current data set, subs in the first half (before meridian flip) has some stray lights on one long edge of the frames. Subs of the second half of the data set are clean (after the flip). 

In PixInsight, the user could select the reference frame/frames for the Local Normalization and the process will use the clean frames to correct the frames impacted by the stray light. 

How do I do this in Astro Pixel Processor? 

Thanks!

@mxcoppell Hi Min,

In APP you can load your lights and calibration frames and then go to tab 3 and click "analyse stars". Once this is done you can check if the reference frame selected by APP is to your liking. If not, select the frame you want in the list of frames at the bottom of the APP window and click the "set reference" button at the top of tab 4. Then click the integrate" button at the bottom of tab 6.

 

HTH, Wouter

Thank you, Wouter. 

In fact, that's my common practice, especially when working with mosaic mode for the data set from the dual-scope setup. 

The question I posted is about selecting reference frame/frames for local normalization correct/local normalization to deal with the stray light situation. And, for local normalization, multiple reference frames could be selected for the LNC/LN in PixInsight. Just trying to see how to do this in APP. 

No worries, if this is not part of APP functions. We could always fall back to WBPP.

@mxcoppell Ahh yes I misunderstood. This indeed is not possible in APP.
