I got the comet with a RedCat 51 last night. This has the same aperture as a Seestar 50 so it should be in range of those now although I had the advantage of a cooled camera and a dark sky at 2100 m on La Palma!

The magnitude estimate on that image is probably rubbish since it is contaminated by stars but it is brighter than I expected.
