Mosaic normalization issue

OK, I may have fixed it.  I did the above process again, but with the following changes:

- on Integration, changed Multi band blending to 15%, and set LNC from OFF to 6th degree, 3 iterations  (I had LNC off before because I thought the scale of LNC was much smaller than panel size)

Which of these was the magic bullet, or both ?  I think it is vastly improved but not quite perfect, are there other settings which could improve it?  

Thanks,

@rkmvca It was all of them. There are some good how-to`s in this Forum in regards to Mosaic. In general the following is recommended:

3: Analyse Stars = 3000 or more

4: scale start/stop = 1/15

5: normalization mode = advanced

6: LNC 4th degree and 3 iterations - increase slowly as needed

6: enable MBB - set it to the percentage of your panel overlap, usually 15-20% works fine

As you figured out, both LNC and MBB have been important for your goal. I would say it is the mix 😉

Thanks, much appreciated!  If interested, here is what I ended up with after a sort of HOO processing:  (abut 72 minutes of light per panel, 130mm refractor)

Hi Rich @rkmvca,

Great result !

Indeed, like Patrick @artaios indicates there are 3 settings that control how well the images blend.

1) normalize, advanced mode will work better then regular mode in this case for sure !

2) Multi-Band Blending is the main blend technique, so very critical to smooth difference in illumination between the panels. Setting MBB even to a higher % can result in more improvements in some cases.

3) Local Normalization Correction, is responsible to try to remove different gradients between the mosaic panels, so also adds to the mix to improve things.
