ES Reid Checked Telescope
Es Reid is highly regarded in the optical industry so to ensure our William Optics triplet refractors perform at their very best we send them to him for checking and, if necessary, tuning on his optical bench.
You can order your telescope with confidence knowing it will 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!
You know it makes sense :-)
Checked & tuned, for details see here.
Latest model with 3.5-inch Crayford V-power focuser featuring a turn/click to lock eyepiece holder, a new central lens element and new steel lens cell.
NB: Can also be supplied with Feathertouch 3.5" focuser & Rotolock.
The William Optics FLT 132 features a new triplet objective with Ohara FPL53 glass for the ED element and a new improved central element that provides superior contrast when compared to the original design. A new robust steel lens cell holds the optic securely and precisely at very low temperatures without fear of the cell pinching.
