For sale a 9” (228 mm) f 7.7 achromatic refractor.

Handcrafted by Istar Optical to excellent performance. Optical test images of the lens and reviews are available.

This 9" refractor telescope OTA features only high-quality parts:

- Istar 9” achromatic lens in push-pull lens cell
- Professional grade tube
- Precision-machined lens cell holder by Sky-Meca (France)
- CNN machined custom endplate
- 4” Astro-physics focuser
- Parallax tube rings
- Astro-physics ribbed plate.

The lens is in excellent condition, though it may need to be cleaned if you wish to. This Istar 9" refractor is a sublime equipment for visual deep-sky observing, for which it is designed and built for. Simply mind-blowing experience and IMHO it beats larger mirrors hands down. Because it is a fast Fraunhofer achromat, please expect very sharp images below 300x magnification. I used the telescope with a temporary dewshield, I can include it for you free of charge if you need it.

Review and images of this telescope available on Cloudynights articles/reviews and on Istar optica's website.

Reasonably priced for 10,200 USD plus insured shipping. For comparison, a similar APO costs about $50,000 USD.

PayPal only. I may consider trade for a smaller quality refractor (4-6") plus cash.
