Planetary Nebula, M57
Some time ago we wanted to start making a deepsky object with a focal greater than 600 mm of a 80ED Skywatcher .
First to see the optical quality of the tube as far we have exclusively used for planetary and otherwise see the capacity of the Celestron CGEM mount with 2 meters of focal. To do that we needed a small and relatively bright object and the ideal candidate was M57, the famous and well-known planetary nebula in the constellation of Lyra.
Telescope: Meade LX200R 8"
Camera: ATIK 314 L + binning 2x2 (1.2 arcsec) because without binning we oversampled the sky with 0.6 arcsec.
Exposure: 53 x 60sec, calibrated with 12 Dark shots and no flat.
Guided with: PHD + Lunatico solution.
