Back in 2012-14 I completed the Herschel 400 visually with a variety of telescopes, mainly with a SkyWatch 12" SynScan Dobsonian. Since then I've done a good deal of imaging using the various telescopes of Slooh.
Many of the Herschel 400 are visible as only faint patches with the 12" dob even from the darkest of skies. In early 2024 I wondered what a comparison would be with the various Slooh images I'd captured of the same objects.
Below is a somewhat side-by-side comparison of what I saw visually ten years prior to what I'd captured in the interim. The "somewhat" refers to different visual vs. imaging fields-of-view and alt-az horizontal visual vs. equatorial imaging orientations.
North is up and east is to the left in all the images.
