As summer draw closer, I set out to try and build a bigger mosaic. 2x7 panels.
Nothing fancy, just a small constellation.
I have acquired 1 hour of data for each of the 14 panels and then I need another 6 to plug a few gaps.
Each individual frame is good, and all have been processed in the following way:
- Calibrating, normalizing and stacking individual color channels
- For each color (R, G, B)
- DynamicCrop
- Imagesolver
- GraXpert
- SpectrophotometricColorCalibration
Then I have build up the mosaic in blocks of 4 panels (2 rows).
Which have then been joined together etc.
Individually, the gradient corrected frames seem great.
When I start to join them together in larger mosaics, It's evident that some things off.
This is just a "ScreenTransferFunction" stretch of the image.
I am wondering if it would make sense to apply something like LinearFit to all my images. Looking at statistics for the individual color channels for the different panels, I can see that there are significant differences in the Median in the images.
I am trying to figure out what I could do, to make the effects you see in the image, a bit less dominant, before I do more processing. .
Any input on processing larger mosaics would be greatly appreciated.
The square in the "bottom" that's of bad quality needs replacing.
Thank you
