This video was taken aprox 15 mintues before official sunrise 6am. With the 10fps, the image scale and the toucam 840k, this is as close to sunrise as I can get. The seeing must have ok, because I put in the 4mm TMB Planetary eyepiece after imaging and the detail was very nice.
Mirror and ambient were within the “.5 degrees” range.
Impresssive image - and I say that with considerable envy, as I have a similar setup to you, but never came within a bull's roar of that sort of detail. I have a 10" dob (Bintel) and the Toucam 840k but I've not been able to get anything that shows even a hint of Jove's rings...
You've done well!
