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.

You know it makes sense :-)

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

Sky-Watcher Professional ESPRIT 3-Element ED apochromatic refractors offer optical performance rivalling 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!  

An M48-fitting doublet field flattener is also available to flatten the field and minimise aberration and distortion. When used with the field flattener the Esprit-80's imaging circle is 33mm.

The M48 fitting provides a large clear aperture to reduce halation and a precision thread ensures the triplet and doublet lens groups are precisely aligned on the optical axis perpendicular to the image. 

Price includes storage case.

Esprit 80
Monday, 21 May 2018  | 

I recently upgraded to the Esprit 80 (from a very competent 130PDS).

The weight, glass configuration, wide FOV and F/5 makes this a perfect imaging scope for me.

I took the option to have the scope Es Reid bench tested prior to despatch and it was declared 'Excellent' (first light with the scope very much confirmed this with pin point stars across the field).

The scope came very well packaged in its very sturdy aluminium case.

The scope itself is very well finished and screams quality. The focuser holds the matched field flattener, ZWO EFW, spacers and ASI1600 without issue and during a 40 min image run there was zero movement.

Having a foot rather than tube rings is a curious decision by Sky-watcher as it's clearly designed for imaging but this is an extremely minor quibble and the Esprit is easily mounted onto a vixen dovetail. I had tried mounting it on an existing Sky-watcher dovetail but this didn't work so FLO recommended a suitable alternative (the ADM Vixen-type Universal Dovetail bars fit the Esprit shoe perfectly).

The service received from FLO throughout the transaction was excellent, as usual.

I purchased the scope mainly to use combined with the Quark Chromosphere solar Filter.
I experienced my first light during the March 2015 solar eclipse and I was totally blown away by the views of both the prominences and surface detail that can be seen.
I have also used the scope to view the stars and Lunar surface, the sharpness of the detail seen and the wide-field views of the stars are nothing short of fantastic.
The scope itself is extremely well built and has a top class finish. I am sure I will be using this scope for many years to come.
