I shopt this on numerous nights in late November thru mid December 2021 in narrowband with a C11 on the AP1100 mount, and ASI6200. It has 199 x 300s of Ha, 202 x 300s of Sii, 181 x 300s of Oiii, for a total of about 48 hours of light. This was rendered in the HSO pallet with green shifted a bit toward yellow.
My first attempt at the Pleaides, I think I over-expoed a bit, and would like to try from a dark site with much shorter exposures. This one is at 540mm with an NP101is, and 141 Luminance at 120s, 9 Luminance at 240s, 47 Red @ 120s, 63 Green @ 120s, 46 Blue @ 120s, and 10 Blue at 240s. About 11 hours total, taken from my home, mount was an AP1100AE
The PacMan nebula is a bright emission nebula in Cassiopeia at about 9500 light years from earth. This image is taken with a C11 with focal reducer (0.7x) at F7, over many nights (interrupted by clouds) from 10/14/2021 to 11/25/2021. It has 144 exposures of Ha at 300s each, 144 exposures of Sii at 300s, and 128 exposures of O-iii at 300s for a total of 34.6 hours of integration. The rendering is in the SHO pallet, with Ha used as a synthetic luminance.
