TS 50mm f6.6 APO refractor and ED telephoto lens Aperture 50mm and 330mm focal length.
Focal Ratio f6.6 – 50mm ED high quality air spaced doublet lens.
A powerful “pocket” scope with the same optics as the legendary Stellarvue ED50 NB. Tube clamp has some scratches around the securing screw and OTA tests very good optically.
The Skyliner-250P Classic 10” Parabolic Dobsonian telescope offers an incredible aperture-to-price ratio. The Dobsonian mount, popularized by John Dobson in the 1970s, is a simple and efficient method of mounting a Newtonian reflector. Fast and easy to set up, the Dobsonian mount consists of a box-type mounting which allows the telescope to pivot in altitude, while the box itself is rotated on a base in azimuth.
The TS 70mm f6.78 Quad is a great travel telescope for photographers and observers. The corrector is built into the OTA, so you just focus and you’re automatically at the optimal distance. The TSED70Q has a comfortable working distance of 135mm from the 2″ end, so you can easily use 2″ star diagonals and eyepieces and still reach focus.
