I dusted off my ED 80 Pro and this is its first light in 10 years! HEQ5 Pro F7.5 600mm Focal Length of the M20 Trifid Nebula with L Extreme and L pro stars. 130 x 240 sec + 20 x 240 sec. I used a non powered Astro Tech Flattener (no reducer) with ASI 533 MC Pro. The Asi Air Pro makes everything much easier!

(To get closer I chose not to use a reducer but just a flattener - guiding worked out ok)
Thanks
