Phantom CFL 170-7 APOTriplet OTA

[Ales - iStar Optical]

Hello everyone,

after successfully designing and building our brand new Phantom CFL 140-6.3 we are now increasing the aperture size to 170mm of clear aperture (178mm lens diameter), designing and producing Phantom's 140s bigger brother. We will use a similar combination of glass types, meaning fluoro-crown matched with Lanthanum and N-SK14 dense (heavy) Crown optical glasses. The results we have achieved are extremely good, similar to the 140mm F/6.3 APO Triplet.

We are planning on producing the first 10 units in about 3-4 months from now and anyone interested can contact me for details.

Pricing should be at around $6500 but if we manage to find more customers the price of this brand new APO Triplet can drop as low as $4,500 per set (lens in push-pull metail cell)

The complete OTA will follow soon after introducing the lens in cell.

For detailed info please write to [e-mail] or call 619-452-9820 (US)

Take care, everyone,

Ales

Hi, how is the progress with this. I live in New Zealand and would like to know if you ship internationally. Thanks Larry

Hello
We have completely scrapped the 170 mm F/7 APO Because of the brand new revolutionary design that we came up with several months ago. We have achieved a fully corrected triplet design in 188mm F/5.9 and 212mm F/5.9. Both of these will work seamlessly with the brand new Starizona Apex 0.65x reducer-flattener utilizing 5 lenses with 2x ED elements. Extremely fast F/3.8 can be achieved by pairing these newly designed iStar APO triplets with Starizona Apex Full Frame RF.
But in order to produce these I have to gather at least 35 customers willing to make approximately 50% pre-payment. I’m hoping that the moment more customers realize what kind of quality we offer in existing Phantom 140 I will find at least 35 amateur astronomers willing to invest in these large APO systems.

Larry, we have updated the entire design and made it MUCH better and MUCH faster. We can produce 180mm F/5.9 super fast APO, quality similar to our Phantom 140 F/6.5. Our Phantom beat ALL of the competition regardless of the price point!!!!
