Stellarvue SV110-25SV 110 mm ED Doublet Refractor Telescope - 2.5" Stellarvue Focuser
Features a 110mm f-7 ED doublet objective with a superior, fully rotating 2.5" dual speed focuser, with 2” and 1.25” compression ring adapters. The focuser has three focusing knobs, one on the left and two on the right. The single knob on the left and a larger knob on the right provide coarse focusing. On the right side is a second, slightly smaller, brass colored fine focus knob. This fine focus knob has an 11-1 rotation reducer, allowing for fine and accurate focusing. A tension adjustment set screw is positioned under the focuser and a thumb screw allows for locking the focuser. The drawtube is inscribed with a millimeter scale on top. This focuser is larger in inside diameter than the 2” focuser and can lift heavier weight. Two 5 mm threaded holes on top of the focuser allow for the attachment of a finder scope. The focuser is fully rotating, only requiring the loosening of a knob.
This is the telescope to buy if you are interested in both visual use and imaging. The 2.5” focuser works with the threaded SV field flattener. This focuser is smoother, more stable and has a higher lifting capacity than the 2” focuser.
The OTA of the SV-110ED is also super versatile! Screw off the 21mm extension and you can use a binoviewer without additional adapters. The ability to shorten the optical tube assembly also means the SV-110 is airline carry-on compliant, so you can take your telescope on vacation.
The dual hinged mounting rings that come standard with the 110ED work with various mounting plates. Imagers prefer dual rings as they are more stable than a clamshell when mounted further apart.

Fully multicoated ED objective lens: With a 110 mm f-7 extra low dispersion objective lens, this telescope presents an excellent star test with color correction that is far superior to a typical achromat. The lenses are hand figured by a master optician to a high Strehl ratio. These are not mass produced, machine made lenses. This telescope uses an ED objective lens that has been tested three times in the USA, for added quality control. We accept no compromises in this telescope's optics.
