ES Reid Checked Telescope
Es Reid is highly regarded in the optical industry so to ensure our refractors perform at their very best we send them to him for checking and, if necessary, tuning on his optical bench.
Inevitably some telescopes require more time on the bench than others but we average the costs so this extra layer of quality control adds only £75 to the purchase price.
A small price to pay for peace of mind.
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.
The William Optics GT-81 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 an upgraded 2-inch dual-speed Rack & Pinion focuser.
The Hotech SCA Field Flattener is an excellent match for this telescope.
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 mounting bracket, carry handle, finder/guider rings and high quality soft carry case.
