M101


Image Description and Details :

M101 taken with a Newton 250 f/4, AZEQ6 and a ATIK ONE monochrome camera.
53 exposure hours in LRGB-Ha (38 L, 11 RGB, 4 Ha), under various Moon conditions and always polluted sky (SQM 19,7 without Moon)
But the seeing was good, allowing great resolution.
Hundreds of very far and faint galaxies can be seen in the background.
