This is a 2 x 1 mosaic acquired over two nights (scale reduced to 50% of original).
This is my first (successful) mosaic.
It was assembled in PI using Gradient Merge process. The overlap region is the vertical strip in the middle of the image. I had to use the geometric correction to build the mosaic, because the image is covering a large field.
The FWHM is 7 arcsec, I found it difficult to go below 6 arcsec with the hyperstar on my C8 ... I dont think this is very good.

Pre-processing done in Pixinsight :
- overscan area offset correction
- bias correction
- flat correction
- hot pixel correction
- debayer
- registration
- stack
Processing done in Pixinsight :
- backgroung color neutralisation
- color calibration using nebula
- gradient merge mosaic
- residual sky background substraction
- color saturation boost
- green neutral
- non linear image creation
- erosion
Final image :
- jpeg calibration done in Mac Photo scaled at 50%
