Stellarvue SVR102T-25SV APO Triplet Refractor Telescope
|The SVR102T-25SV is a high performance 4-inch f/7.05 air spaced apochromatic triplet refractor featuring the Stellarvue 2.5-inch rack and pinion focuser. |
The SVR102T is an extremely high performance, light weight 4-inch f/7 (715 mm focal length) air spaced apochromatic triplet refractor. This is Stellarvue's latest lens design featuring a certified, high Strehl objective. It is available in your choice of white aluminum or carbon fiber optical tubes. The standard models are equipped with the 2.5-inch Stellarvue dual-speed, rack and pinion focuser with 1.25 and 2-inch adapters. Optional versions using either the 2.5 or 3-inch Feather Touch rack and pinion focusers are available at additional cost.
All SV102T telescopes are shipped in the Stellarvue C9S soft case. Dedicated photographic field flatteners are available that thread onto each of the focuser options, allowing a threaded coupling for imaging applications.
Standard Models - SV102T-25SV and SVR102T-25SV
The standard versions of this telescope includes Stellarvue's own robust 2.5-inch dual-speed rack and pinion focuser. We think that most people will be satisfied with this focuser. The carbon fiber version weighs 9 lbs. and the pair of supplied split rings weigh an additional 1.6 lbs.. The focuser unthreads resulting in a tube assembly that is only 20.25 inches long, well within airline carry-on size limits. Now you can easily take a world class apochromatic refractor on the plane with you! The certified optic is essentially perfect and comes with our interferometric test report showing it is 95 Strehl or higher. This is as good as it gets which means you will see or image everything the atmosphere will allow! Like all Stellarvue telescopes, this instrument is triple tested including a star test by Vic Maris.
