To give you a few examples: Asteria TCR 180 F8 R35 SLIM, Asteria TCR 180 F12 R35 SLIM, Phoenix TCR 204-8, Asteria 204 F8 R35 SLIM, Asteria 204 F12 R35 SLIM and so on up to 250 F11 R35 model which has been ordered by one customer recently. cheers, Ales Post Extras:       ISTAR Optical Vendor- IStar Optical Reged: 08/09/09 Loc: Page, Arizona Re: Red Hot New Concept OTA's [Re: ATM57]       #5622295 - 01/14/13 09:08 AM Edit   Reply   Quote Quick Reply   You are absolutely correct. Thanks God that some of the guys with more open minds do realize these advantages even without looking thru one themselves. Only basic knowledge of optics or even just common sense is what one neeeds to make a sound decision. We will definitely show these in public and I cant wait for first customers so they can do this job for us.. on much bigger scale. I do not argue with any hard core disbelievers, I simply let the course of time and hands on experience to prove them wrong. I know one thing, this is definitely a step back to 1600 century design style.. People including most manufacturers will simply repeat one design over and over. The idea behind is: if it works why fix it.. well, I can not agree. Things can usually work better even if they "work well" now.. Franky, I would not go public with some weird design if I was not more than sure that it works at least as well as closed tube design... I know that I would be eaten alive if I did... have a great day, stay in touch. I wont be able to get on line much during my upcoming trip abroad. Due back in my office by end of February 2013, cheers, Ales Post Extras:       ISTAR Optical Vendor- IStar Optical Reged: 08/09/09 Loc: Page, Arizona Re: Red Hot New Concept OTA's [Re: BillP]       #5626074 - 01/16/13 12:01 PM Edit   Reply   Quote Quick Reply   Hello Bill, we will produce these for CLASSIC ACHROMATS? 150 F12 (now produced) 150 F15 204 F/8,8 and for R30 and R35 special doublets 150 F12 R35 SLIM 180 F8 R30 180 F8 R35 SLIM 180 F12 R35 SLIM 204 F8 R35 SLIM 204 F12 R35 SLIM 220 F9 R35 SLIM (F-ratio MAY change on this one) 250 F11 R35 possibly APO Triplet 160 F12 that would be it for some time, but enough for anyone to choose the right one I believe, cheers, Ales Post Extras:       ISTAR Optical Vendor- IStar Optical Reged: 08/09/09 Loc: Page, Arizona Re: Red Hot New Concept OTA's [Re: johnnyha]       #5626081 - 01/16/13 12:04 PM Edit   Reply   Quote Quick Reply   Johny, TCR scopes will have both front and rear dew shield style attachments, we have the design layed out, now sourcing for the right materials. So people can choose what works best for their own environment cheers, Ales Post Extras:       zjc26138 Loved By All Reged: 02/24/05 Loc: Mingo Junction, Ohio Re: Red Hot New Concept OTA's [Re: ISTAR Optical]       #5626202 - 01/16/13 01:26 PM Edit   Reply   Quote Quick Reply   I want the TCR 180 F/8 R30. Gotta start saving now.

We will have few sets of the original R30 doublets (about 40 percent heavier lens) but to off-set this, we will offer the finished OTAs in TCR construction with an appropriate discount. The new R35 SLIM doublets are now produced in following configurations 150 F5 R35 SLIM 150 F8 R35 SLIM 150 F12 R35 SLIM 180 F8 R35 SLIM 180 F12 R35 SLIM 204 F8 R35 SLIM 204 F12 R35 SLIM we have an inquiry from one observatory/astronomy club for 230 F20 R35 SLIM, if there is anyone else interested, let me know. Producing two sets will be considerably less expensive than one single lens, best regards, Ales Edited by ISTAR Optical (01/17/13 04:12 AM) Post Extras:       ATM57 member Reged: 01/01/10 Loc: Tehachapi, CA Re: Red Hot New Concept OTA's [Re: zjc26138]       #5628194 - 01/17/13 02:29 PM Edit   Reply   Quote Quick Reply   Yeah, I'm looking at the 204 F/8.8. R30 or R35 SLIM would be a plus but funding would dictate the choice.
