I looks like a very sweet scope! I hope you will share your experiences with it; including your experiences with cooldown time of the 6" objective which is of interest for other people in the Northern European climate zone.
Oh, rest assured, that there will be reports of my experiences with it. Lots and lots of reports.
The cooldown time will obviously vary enormously, depending on the temperature difference, but in winter I anticipate a cooldown period of around an hour, with the scope being very usable at medium to medium-high magnifications after half an hour or so, much like my 6" f/8 newtonian and my 6" f/8 achromat. We will see.
