Thanks all for the answers.
Even with a low profile SCT focuser? And what about LX65?
Would using a quality helical focuser after a 2" diagonal be a good idea? I really hate image shifts...
Defintion of "GO" for me is a single trip to a car, and setup time of ~10 minutes. My main telescope is a 12" Newtonian on AZ-EQ6 ... The reason for grab and go is not only to save time... it's lack of motivation to carry and assemble the 12" Newt for a short session. Especially when you have little kids, and sometimes all you wanna do is just to relax and sit near an eyepiece.
I only need GOTO for tracking. It takes me less than 5 minutes to align my AQ-EQ6, sice I don't really care for its GOTO accuracy, and alignment for tracking is much less demanding
I'm not from US so sale isn't really relevant here... And I'm tending to lean towards Meade ACF (maybe with the LX65 mount) - it costs exactly the same as the "regular" C8 ... Can I mount Meade ACF on a Nextstar? I've read that Meade's SCTs are a bit heavier...
Why? isn't waiting is for cool-down which reflectix would prevent?
Regarding air travel - I meant as a carry on of course. I think a 8" SCT should fit a padded camera bag. Anyway It's not a must.
The hardest part is over though, after I explained my wife for an hour "why that 3rd telescope is an absolute necessity"
The idea is that you DON'T want cool down! The rapid cooling going from a warm house, say 70F, to a cold outside location, say 20F, is what causes the thermals which cause the lousy seeing. On very cold nights your mirror will never cool to ambient. However, Reflectix keeps the warmth from radiating out of the tube, thus reducing the thermals to negligible, thus providing excellent sharp views from the very moment you take it outside.
I have a Unistar mount on a Sirius tripod, covered, right outside my door. We're expecting 20 inches of snow in Western Massachusetts tomorrow. At sunset it was 24F, but clear. I took out my Insulated C6 to get a quick view of setting Jupiter, very sharp at 100X. Then Venus, quite clear. Then Saturn at 187X, still sharp! The Crescent Moon was next and terrific. Then over towards the East for a nice Uranus at 100X, then at 187X one of the moons, Miranda according to my chart. Finally back toward the South for Neptune, and as with the others, great at 100X and 187X.
All in 45 minutes. Without insulation, this wouldn't have been possible! Heck, even a 4 inch refractor would taken 20 minutes to reach semi-ambient with a 46 degree temperature delta (70 to 24).
To me, this is the ultimate GNG. The Baader Zoom is already in the diagonal, the Reflectix always affixed to the scope AND the Dew Shield, so it's grab the OTA in one arm, out the door, pull the cover off the Uni, attach scope, start observing.
How long was that?? 2 minutes??
