| Comments: |
First light for
my new portable Instrument. It is a Newtonian telescope with 46%-Obstruction,
MPCC-Coma-Corrector, enough backfocus for the Filter wheel and CCD-camera.
The raw-stars are around 4 arc-seconds FWHM. The pixel size is 6,45
micrometer - that means, the Astrograph produces stars around 8
micrometer (like a Takahashi Epsilon - for 1/6 the price). A night with average transparency! Picture downsampled 30% for a better view. The bright Star is 1 mag. Regulus. |
