This is just a short addition to Mike's message regarding new ISTAR scopes in stock. We have just finished assembly of another 5 scopes in our European manufacturing plant so now we have total of 37 brand new scopes incl. the complete Perseus line in 150mm and 204mm, also Phoenix in 150mm and 204mm, more Asteria OTAs, etc.. we will ship first batch of 15 in about two week time so talk to Mike Harden about your orders, there is no waiting time on most of our scopes now. We are also finishing producing a large lens batch, all lenses on our order list will be shipped out in less than three week time.
We are even preparing three Phantom CFT 152-8 pure CaF2 Fluorite Super APO triplets. Also a brand new Phantom CFT 175-6 is being designed and produced which is a super fast 175mm lens diameter astrograph with an optional field flattener. We will also introduce a brand new super compact, extremely fast FPL53 APO triplet in 130mm aperture and F6, both as lens in cell for 2375 dollars or as a complete OTA under Phoebe WFA 130-6. Price of the OTA will be released soon. Also 3 more models with our R30 doublets are being prepared, so stay tuned,
cheers,
Ales

But of course Mike...  Now seriously, we will produce first unit this summer and you will get to keep this new beauty in our Florida stock and show this scope around.. at all local astronomy shows and star parties. I strongly believe that a CaF2 (pure mineral Fluorite) Super APO Triplet is by far superior to any CaF2 APO Doublet. The most important reason, besides the unsurpassed image quality in a Triplet design, is the physical instability of this super expensive optical material. The CAF2 is normally sandwiched in between two Crown lenses with the entire assembly being completely water tight and air tight. So no moisture, not even traces of chemicals can enter the objective lens assembly, especially the CaF2 lens. If the CaF2 is exposed to air (no way around this in a doublet design.. the moisture will start damaging the lens. So only in a few short years people may end up with a damaged CaF2 lens inside of their refractor.. a hefty price to pay for choosing a doublet over a full blooded Super APO Triplet....everyone considering a CaF2 APO doublet should get educated before they spend this kind of money on their next scope. Personally I would never go for a doublet if I had a choice. Unless the doublet is considerably less expensive, like half cost or such… The CaF2 Triplet will optically outperform any doublet by a comfortable margin while being completely SAFE to use even in a high humidity environment. Besides this 175 F6 CaF2 Fluorite Super APO we will introduce a 127mm and 100mm lenses. Those smaller models will be introduced in 2013, the 175mm triplet will be available by late summer or fall 2012 Cheers, Ales |
