Dear fellow amateur astronomer,

   Thank you for visiting the web site of ISTAR Optical - your manufacturer of quality refractors and accessories at down to earth prices. We are working hard to add new products to our existing line. Please check frequently for updates to our web pages. Our plans include designing and manufacturing the widest selection of objective lens based optical systems ever offered by a single manufacturer. From an inexpensive medium diameter achromatic doublets to large Fluorite and ED glass APOs, Super APO, multi-element Astrographs. We are currently designing several new products. Two versions of Super Achromatic and Semi APO doublets offering 30 and 50 percent reduction in chromatic aberration and substantially smaller lens spot size have been recently added. We are developing a new line of APO Triplets in sizes 144mm to 180mm, 7 element Super APO astrographs, SCT correctors, chromatic aberration reducers and many other exciting products. At ISTAR we do not produce in mass quantities. Each telescope and optical system is custom designed, assembled by hand and individually tested. We also offer custom optical and telescope design. Please contact us to find the product that fits your needs and budget. We hope to hear from you soon and your support is greatly appreciated.

Clear Skies!

Your ISTAR Optical Team
