First light for the STL and the secondary focus of the 16" cassegrain
at f/10.
I have chosen this target, as the seeing was good, but the transparency very bad, so I decided to go for a "bright" object. Raw
FMHW was 2" and I took very short exposures for the center to avoid too much saturation in the stars for keeping them tight.
I was surprised about the relatively low distortions in the outer areas, no field corrector used.
Processing took quite a while, tried to preserve the right color balance, but increased saturation. Blending of the inner and outer areas was done carefully with several layers.
No deconvolution, only unsharp masking in different steps.
