That's quite unfair. A month after the 140EDF was offered, I wanted to order one. Marj suggested I buy a Tak because I'd be very lucky to ever receive the 140. So I did. Roland & Marj didn't loose a sale - they sell everything they can make at a price that suits them.

Roland has said in print that there is no reason for anyone to have to wait 10 years for one of his scopes with what is available today.  We forget that most of these folks, (Roland, uncle Al, Scott losmandy, etc) are amateurs that started their businesses out of love for the hobby. Having listened and or spoken with all of them, I am pretty sure the WE are a lot more uptight about who buys what than they are!lol.gif

The Dual ED scopes are presently sold by FLO in the UK under their own brand name: Stellamira.

When they appeared FLO said they came from Longperng and I recall seeing them on the LP site a few years ago.

They seem to have finally arrived.

 

Only 2 are 2xED's, the 104mm and the 85mm. The slow 80mm is a standard ED doublet.

 

If I recall FLO said they are FPL53 and FPL51 glass, no idea what the middle bit is:: Lanthanium apparently. Willing to accept the FPL-53 and FPL-51 types.

 

From the FLO Site:

To reduce chromatic aberration to an absolute minimum StellaMira ED2 triplet telescopes feature two Japanese Ohara ED glass elements (FPL53 & FPL51) together with a third element from Lanthanum.

Or read the 104mm Here:

 

FLO only presently sell 2 variants. So will be interesting to see what else is added to the collection, presuming some additions are made.

 

FLO have I expect realised that people want to know the glass and as they are under their own brand name they can give out that information.
