Description

Just for testing guiding and focussing quality, made 40x60s exposures somewhere in Orion (running man NGC 1977 in center by chance), used 25x60s.
Guiding, focussing, resulting FWHM all ok, but nebula structures are missing (25 minutes are not enough at 1200 mm FL and OSC), instead spider misalignment and three mirror holders are clearly visible as artifacts by extreme gamma stretching (5.0), needed to cover the huge dynamic range between nebula and faint stars vs. the bright stars.
