When will LNC 2.0 be implemented? I am stuck with my 72 panel Mosaic having Checkerboard artefacts.

Orion 72 p St med 259200.0s NR x 0.5 LZ3 NS full eq add sc BWMV nor AA RL MBB50 4thLNC it3 Stretched 1600px

I re-stacked the 72 panel stacks using LNC and MBB, but can not get rid of the "checkerboard"-effect as seen in attached example. I hope that version 1.061 with LNC 2.0 will take care of this, but when will that be?

Dear @kees_scherer,

I am about to release APP 1.060:

https://www.astropixelprocessor.com/community/release-information/astro-pixel-processor-1-060-preparing-next-release/

After it's release, I'll work on LNC 2.0 😉 for the 1.061 release. It's hard to tell when it will be released, since a new LNC version should take some time to implement. It's a very complicated algorithm already.

The checkerboard pattern only seems to manifest on some datasets and I think it has to do with a combination of

  • ligh pollution gradients (which are still there in even 3nm H-alpha exposures)
  • the amount of overlaps between the frames
  • the current implementation of LNC isn't adaptive on the widht/height of the frame overlap areas which it probably should be

Kind regards,

I was hoping that mono data (multiple filters) could be processed together at same time with the 1.060 release.

Is this included in this version?

Too much work to calibrate and align 4-7 filters separately for me.

Hi Max @titansmoonsyahoo-com ,

Yes, APP 1.060 will have multi-channel and mutli-session support for fully automatic integrations of all channels and/or sessions with matching calibration masters. It will be released within a couple of days now...

Now that APP 1.068 is released and LNC 2.0 would be implemented in 1.061 but still is not? Or did i miss something?

Nope, it is indeed delayed, but kind of on top of the list at the moment. ETA only Mabula knows.

LNC2

I see in the Astro Imaging Channel Presentation that LNC 2.0 development has a priority status. Any news to report?

Let's give a status summary for this thread:

May 12, 2018: "After it's release, I'll work on LNC 2.0 😉 for the 1.061 release". Meanwhile we have 1.061, 1.062, 10.63, 1.064, 1.065, 1.066, 1.067, 1.068, 1.069 and 1.070 and no LNC 2.0 was implemented.  Also no statement on the status other than the presentation for the Astro Imaging channel stating LNC 2.0 has a priority status.
