Last season I dusted off my ED 80 Pro and this was 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. I added to it this season with 15 x 240 sec native (IR block only) to bring out the blue. this is belt moded also.
