Hi - I had an idea!
I wan't to tune my telescope even further - and whats left?
Changing the mirror, in this case the secondary mirror, to a mirror with a strehl ratio of 0,9 which is better than the atmosphere will allow.

Follow me how to prep the mirror and how i mount it on my scope!

My gear:
Telescope mount: Astro System Austria (ASA) DDM 85
Telescope: Teleskop Service N-AG 10 (10" carbon fiber astrograph) with 3" Feather touch focuser and a 3" Riccardi coma corrector / reducer
Filter Wheel: Starlight Xpress with 36mm Astrodon filters
Camera: ZWO ASI 2600MM
