Those clamp rings in the video remind me of another apo, just can't remember what one.

Not likely.

 

Well, depending on what you call "affordable". Chances are if you have $1000 to spend on a single filter, then you might have a different opinion on what you'd call affordable. lol.gif

If it's really ~61mm like speculated, then I hope this will be no more than $800. 

 

Or if this goes the route of the WO Space/Redcat 51... $750 used.

Indeed. If it's not a Petzval with a built-in flattener, there's not much point to this scope.

Already been on the market for over a yr.  TS 61

 

Also. "Radian Telescopes" seems nothing more than another house brand for OPT?

FC depends on focal length not focal ratio ('speed')

I rather have an f/4.5 native triplet that I can slap an additional reducer/flattener on. 

 

Otherwise I'd just buy a sharpstar 61 EDPH with the dedicated reducer/flattener which also goes to f/4.5.

Yep, looks like a rebrand of the Sharpstar 61edphii which retails for $650 with the reducer. Differences are a black and red color scheme instead of white and red, tube rings instead of a clamshell, and no handle. Expect some markup over the Sharpstar price. I’m predicting a $750-800 retail price.

They’re too busy building awesome scopes.

I was thinking that at first, but the Sharpstar is a doublet with "triplet" reducer. No matter how you look at it, there's no way to describe it as a triplet. It's either a doublet or a quintuplet (which is of course I'd hesitate to call it as such).

Interesting. Didn't know they had a new version.
