Odd Result with LNC...

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.

Odd Result with LNC again

I occasionally get odd results with LNC.  This is an Ha stack (13 x 1200s) - it is one panel from a wide view of M42/NGC1999.  I processed this in the sual way with BPM and Master Bias, Dark and Flat. 

This is the stack with no LNC:

Orion2 Small OK

 

And here are exactly the same settings, but with LNC Degree set at '1' and Iterations set at '3'.

Orion2 Small BAD

Any ideas?

Hi Steve,

Thank you very much for sharing.

That looks very odd, especially since only 1st degree LNC was used?

Can you send me the data so I can test what's happening?

I will work on improving LNC soon, so it will be very helpfull if you could send me the data so we can further improve the module 😉 

Kind regards,

Mabula

Happy to Mabula.  What do you want?  All 13 calibrated and registered frames?

Hi Steve, yes, that's perfect, then I can duplicate the behaviour and hopefully understand why it happens and remedy it 😉

You can send it to me using wetransfer.com  use support@astropixelprocessor.com as address

OK.  I just sent the files (zipped).  Neer used wetransfer before, but it all seemed to go smoothly.  I'll be interested to see how you get on.

Hi @gnomus,

I did download the files, haven't tested yet, but will sure do. First I need to release APP 1.057 (with fix for your multi-channel processing problem), then in APP 1.058 I probably upgrade the LNC tool 😉

Thanks for sharing 😉
