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.
This was my first light (and many more after) with the AP1100AE. I got quite a lot of data while trying to tune backfocus and other aspects of a new imaging train at the same time. This is 205 x 120s of Luminance, 121 x 240s of Red, 111 x 240s of Green, 180 x 240s of Blue, and 30 x 300s of Ha blended a bit in R, and a bit less in Green to give a somewhat orange appearance to star forming regions. That is a bit over 36 hours of total time at about Bortle 7. The images were taken with an ASI6200MM Pro, Chroma filters, and an NP101is.
