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 :-) 

20th Anniversaary Limited Edition - Checked & tuned, for details see here

The William Optics GT-102 APO Triplet refractor features a 3-element f/6.9 objective with an Ohara FPL-53 extra-low-dispersion glass element for optimum colour correction and an all-new 3" Victory Edition Diamond  dual-speed crayford focuser. 

The Hotech SCA Field Flattener is an excellent match for this telescope.  

A William Optics 0.8x focal reducer is also available to reduce the focal-ratio to a fast f5.52 

An excellent choice for astrophotography!
