FLO tests all William Optics triplet refractor telescopes before dispatch.
You can be confident your telescope will, from the outset, have well figured optics, negligible false colour and spherical aberration, and no astigmatism (the bane of any optical system!).
Star shapes will be round, not triangular, oval or egg-shaped!
The William Optics GT-71 APO Triplet refractor features a 3-element f/5.9 objective with an Ohara FPL-53 extra-low-dispersion glass element for optimum colour correction and a new upgraded dual-speed 2.5-inch Rack and Pinion focuser with 1:10 Dual Speed.
The William Optics 0.8x focal reducer is also available to reduce the focal-ratio to a fast f4.72.
An excellent choice for astrophotography!
Includes tube rings, carry handle/guider mounting saddle.
390mm Fully Retracted
Upgrading from a Z61 doublet which performed exceedingly well for wide field work. Haven't had a chance to take the GT71 for its first light just yet but I'm confident it will perform and exceed my expectations. Took a while to arrive due to covid circumstances but the FLO team were very patient on providing updates. As always top service. Thank you again!
I've only had a couple of clear nights so far so haven't had as much playtime as I would like, however from the use I have had I really can't fault it! The images are crisp, the stars are round, and for me the field of view is perfect! It is a very well made little scope and I can't wait to get more use out of it. As always the guys at FLO have been extremely helpful and the scope arrived in perfect condition!
Quite stunning workmanship everything is really precise the focus system is a joy. This is my first refractor I am more than happy with my purchase which I intend to use in conjunction with my DSLR. Took a few weeks to arrive as one of the ordered parts was not in stock and this virus problem. Never the less it arrived when they said it would and was well packed.
