>>>Remember seriously, these forums tend to over blow "EVERYTHING" out of proportion. This whole issue of cool down to a sweet triplet refractor is completely ridiculous, at any level. Anyone that tells you otherwise is just bored and needs to go out and use their gear instead of talk about it out here.
good point, totally agree about cooling concerns being overblown! Some folks even advise choosing oil-spaced apo over air-spaced because of cooling. I've never seen any difference between the two. Bigger heavier OTA's take longer to cool, but it's never been a problem for me, even in winter temps.
In fact, one of the biggest reasons to buy these expensive apos is because they handle thermal issues better than other designs! Every one I've used gives good images after 15 minutes in the cold air. You'll never look into the eyepiece and see heat plumes and thermal problems like other scope designs with mirrors stuck in the middle of the light path.
The Tak TOA is heavy because it's "built like a tank". The old FCT150 was 50 pounds! A lot of people like the robust construction. It's hard to see these under-30 pound apos taking criticism for being heavy, all the various 10-inch and up dobs have several components that are heavier than a 6-inch apo OTA. Many club members I know have to buy vans or pickup trucks to move their dobs and SCT's around.
