Es Reid Optical Bench Test

Following a number of requests we are offering an Es Reid optical bench test for Esprit telescopes.

Es Reid is highly regarded in the optical industry so if you purchase his optical bench test 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!

Because most Esprit telescopes test AOK out-of-the-box (only a small number require adjustment) this extra layer of quality control adds only £75 to the purchase price.

A pre-dispatch optical bench test is now available for this telescope, for details see here. 

The new Sky-Watcher Professional ESPRIT 3-Element ED apochromatic refractors offer optical performance rivaling or exceeding similar telescopes from even the most famous high-end brands.

Designed primarily for demanding astro-imagers wanting high-contrast images full of detail and zero detectable colour fringing, even on the brightest of objects! 

840mm f/7 focal length.

Sky-Watcher Esprit 120 Review by SkyNews Magazine:

"The Esprit 120 has a triplet objective with one element made of prized Ohara S-FPL53 glass. I compared its performance with high-end Officina Stellare and Astro-Physics 105mm and 130mm apos employing similar premium glass. Even at high magnification with a 3mm eyepiece, star images appeared just as sharp, aberration-free and colourless as the best. I was impressed.
On subzero (°C) nights once the telescope cooled down (after 30 to 45 minutes), it exhibited none of the aberration oddities I’ve seen in some test telescopes, effects created by cold temperatures pinching optics. This is evidence of the Esprit’s excellent lens cell design, the area where aspiring apos sometimes fall short."  

A dedicated Sky-Watcher Field Flattener is available that provides a wide 44mm imaging circle for use with a DSLR or other imaging device with a large sensor. 

Price includes storage case.

The Excellent Esprit
Sunday, 2 April 2017  | 

I had some doubts about spending this amount of money on a refractor when I already have a 10" RC that is outstanding for imaging Galaxies etc. But I needed something with a medium focal length for the larger nebulae so braced myself and parted with the cash. I did contemplate sending it back before I used it; glad I didn't. Whilst I have never used another APO of comparable size this OTA has delighted me - the reviews seem to have been spot-on. In spite of what has been written about it I did expect some colour fringing but I am yet to see any at all. I do have the flattener although I don't need it for my current chip size - I bought it intending to go to large format imaging at some stage. Anybody looking for a high quality, mid-sized APO would do well to beat this and I suspect that in terms of value-for-money it is top of the pile. Unless one has cash to burn I can see no earthly reason for the average amateur to spend twice the money (and more) on one of the top Brand names. I really didn't expect it to be this good. JB

Superb scope, I also bought the Hotech flattener thinking I would need it but I don't have any curvature at all at the edge of the fov so haven't used it yet.
I'm getting much clearer detail for my spectroscopy than I did with my old C8. Highly recommended!
