Ok, thanks Bert. It's a lot larger than I thought it would be.
Faint thought, 1 hr and 15 min with a modded Canon. :confuse: maybe 2 hrs to get a similar result with and unmodded one, maybe.

Plus it's a 10" @ 5.6. An 8" @ 6.3 add maybe another half an hour plus to it (all best guestimates). Maybe one day
