This is our smallest refractor. At the heart of this little telescope is a super sharp 60 mm f-5.5 apochromatic doublet objective using Ohara FPL-53 optical glass. It can be used visually as an ultra-portable daytime and nighttime telescope with its high contrast, excellently corrected objective and 2" rack and pinion, dual speed focuser. Drop it in your suitcase and take it everywhere you go! Just attach it to a camera tripod, add your diagonal and eyepieces and you are up and running!
The telescope will work in taking extremely wide field images of the night sky using the SFF60 field flattener. For daytime photography, use the telescope, the flattener and a t-ring to create a super sharp 330 mm f-5.5 telephoto. Images will be on par with telephoto lenses costing as much or more than the telescope/flattener combination. Beautiful astro-photos are possible with excellent color correction. Be aware however, that a fast, small (under 70 mm) apo lens with a field flattener with not be completely flat field. Minimal cropping will be needed. Nonetheless, the 330 mm focal length will provide very wide field images even with the edges cropped.
Mounting this telescope atop your larger refractor will mean you have the most impressive photographic guide scope/finderscope. But since it is a telescope in its own right it will reveal amazing high contrast, wide field views of the night sky. We recommend using our guide scope rings when mounting the SV60EDS atop another larger telescope. This means removing the clam shell and dovetail. We suggest this as a telescope mounted on top of another will never point at the same location in the sky. To do this, one of them must be adjusted. Our guide scope rings permit this adjustment. They also allow the user to center on a bright guide star when guiding.
The SV60EDS has a lightweight aluminum tube and dew shield. It weighs only 3 pounds. It comes with a 2” rack and pinion focuser with a 1.25” compression ring adapter. The focuser is fully rotating with a collet that is identical in design to our renown 2.5” focuser rotator. The tube is machined in two parts. Insert a 2" star diagonal or erecting prism into the telescope to make it a short, lightweight visual telescope that will fit easily in any briefcase! Add the threaded extension tube and our optional field flattener to convert this telescope into a sharp 330 f-5.5 wide field astrograph. Comes with a hinged clamshell ring with removable Vixen type mounting base and finderscope dovetail finder shoe. We are also throwing in a lightweight, padded backpack for easy transport.
Optional: Stellarvue Dielectric Star Diagonal - 2"
Note this information if using a 2" diagonal: One thing about the SV60EDS is that the main tube comes in two parts. We send it with the extension attached for imaging. For visual use, you need to move the clamshell all the way forward to expose the crack between the two tube sections. Unthread the two tubes from each other, put aside the short extension and reattach the focuser to the tube and 2” accessories will come to focus.
