Description

The final image is a composite of 59 x 10s subs, 16 x 20s subs, and 11 x 30s subs on 9/22/2019 shot with a Lumicon deep sky filter and 10 x 5s subs, 10 x 10s subs, 10 x 15s subs, 10 x 20s subs , 10 x 30s subs, 10 x 45s subs and 5 x 60s subs unfiltered and monochrome for luminance. shot on 9/20/2019. All together, there were 161 images at an average exposure of 18s. Stacking produced artifacts at field edges that had to be cropped out; the actual image uploaded has a resolution of 2071 x 1325 pixels. Sky transparency was fair, seeing was poor to fair (typical of Denver) and moonlight did not interfere at the times the images were acquired. All images were unguided. The wind was problematic on 9/22/2019 so I had to review all images by hand to cull those that were too compromised by wind shudder, leaving the image counts as reported above. The total integration time was 0.8 hours.
