Does any one know the
Thread size & pitch
For the 60mm T-II Coronado rich-field Etalon. I'm trying to see if they will mate up to the TV Pronto or a TV 76 cap threads ?Also are the thread sizes "universal" ( to Coronado)
On the type 2' & 3's on the RF Etalons.
I know there's the adapters for Double stacking made by Coronado, are the adapter threads the same
Any info. Would by very cool & welcomed

Thank you
Did you Fab your own ring?
The reason I ask is is 2 fold, 1st is, I got to make one, or where did you get it.
2nd is Actually a, TV rep asked me if I found a solution , or the RF - T2 thread. Size, .to get back to them. , as they wanted to know also.
I said I would
TV Has always been good to me so i dont mind
Thanxs
The 90mm SM II will thread on to a 101mm, 102mm & the Genesis. That's on the daystar site. Old info from when TV sold the "Solaris"

When I had the Gen I SM60, it threaded directly into my Pronto, with no adapters necessary.  I don't believe that the Gen II etalons changed their threading.

Yes...
The threading on the Coronado 60 ll Etalon threads directly to the Pronto. I bought the Etalon + the BF15 filter.
The Etalon was reduced in price by OPT as there was no case, or front lens cap
As an after thought I realised the threaded TV PRONTO lens cap threaded right on to the 60mmII Etalon..fits nicely & doesn't interfere or touch the Etalon lens. OPT was outstanding in there service to me, answered all my questions.. & spent a lot of time & effort to convince me of the quality & integrity of the Etalon
Kyle was top shelf...
I've not used this set up yet. Clouds. But I'm eager to compare it to the Daystar Quark I recently got.a few bugs with the Quark. But I'm finding solutions & limitations to the Quark.
I never dreamed Ha- Solar astronomy would get me so stoked...more posting as results & impressions rollin
