Phantom CFL 140-6 APO triplet reflector telescope

[Ales - iStar Optical]

Hello,

two years ago when we temporarily phased out production of OTAs many of you speculated about iStar's future and some of you did not believe me when I said that we will be back, and better than ever. And the time is here and now!

Let me introduce Phoenix CFL 140-6. Some 10 years ago we offered truly amazing Phantom CFT 152-8. A massively build OTA build around truly amazing 152mm F/8 calcium fluoride triplet. Our new air spaced 140 F/6.5 is the next of the line of iStar Apochromats. Quality of our new triplets is truly outstanding. We are frequently hitting Strehl number over 0.95. The image quality is comparable to the very best (read: "most expensive") APO triplet currently on the market. I can put our iStar 140 F/6.5 APO triplet against any modern TAK, TEC or Zeiss and not be ashamed. Actually, Im proud to annaounce that quality of our new triplets is some of the best achievable and I hope these quality instruments will bring joy to many demanding astro-imagers around the globe.

You can order your new Phantom CFL 140-6 right on our website istar-optical.com

Each telescope is shipped inside high quality aluminum case with handles, locks and excellent quality cross-linked polyethylene foam that will last a lifetime.

For detailed information please contact me directly at [e-mail] You can call me at 619-452-9820, opening hours in Arizona: 10:00AM to 18:00PM

I hope to hear back from you soon

Tom,
please compare our Phantom FCL 140-6.5 APO triplelt with similar triplets made by the very best manfacturers like Zeiss Germany, Takahashi Japan, or LZOS Russia. iStar became known as a producer of high quality achromats, anastigmats and solar doublets but we entered the field of top quality Apochromats exactly 10 years ago with back then the best 155mm F/8 CaF2 (Calcium Fluoride) triplet that was literalily color free. But increase in price of the raw material put us in a very tough spot so I decided to stop the production. So now after 10 years we sourced some great FCD100 and matching Lanthanum from Hoya and we designed this triplet at the best possible quality. We are frequently hitting Strehl over 0.90, most lenses are actually over 0.95 with many in 0.99 range. This is why Im so confident that you will not find better quality out there and even if you find comparable quality it will be at twice the price.
You have a choice to purchase the lens in cell and build your own telescope or to purchase the compete OTA including really superbe quality 4" rack and pinion focuser, CNC machined tube rings, 2mm aluminum tube, rectractable dew shield. I hope to hear back from you soon.
cheers,

Ales
