More Mosaic Madness

[John_Gill]

Hi,

I have two images I want to combine into a mosaic.  So I run the "Star Alignment" with the Working Mode: set to Register/Union - Separate and with a reference image "Right" and target image "Left".  The resultant images are "Mosaic 1" and "Mosaic 2" but these images are both the same as "Right" image.  If I swap the reference and target images around then the "Mosaic 1" and "Mosaic 2" are the same as the "Left" image.  The two images overlap by about half.
The "Right" and "Left" images have only had ABE and had a basic stretch with HT & STF.

Any ideas or suggestions are most welcome.

Biggest suggestion, click on every button and read and fiddle.....   Anyway finally got sorted.

Tips for mosaics builders, I battled to get anything Star Aligned.  I found that after "Rack/Pack/Stack" I cropped the image slightly, then ran ABE. Stretched the image with HT & STF.  Next ran a little MMT and/or TGV.  Using UnsharpMark increased the StdDev a little and a touch of Curves.

In SA, added the Reference Image, Target Image, Working mode set to "Register/Union Separate" and applied to the TARGET IMAGE. 

This created two separate images.  In GradientMergeMosaic added the two new images and then then after a few minutes the mosaic is done.  Brilliant, Wow!!

As a side note, I created two rows of 5 images each.  Ran SA and then GMM.  Each row image is 1.9GB and combined to a 3.5GB file.  The SA found 22 000 stars and the GMM took 2.5 hours to merge.  This was done on my i5 laptop running Windoze 10 with 8GB ram.

Hope this helps someone.
