About this product

Model:  esprit-100-triplet
Part Number:  10244

Optical Bench Test

FLO tests all Esprit telescopes before dispatch. 

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!

Price includes a pre-dispatch optical bench test. 

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

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-100's imaging circle is 40mm.

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 100ED - A superb OTA
Monday, 28 June 2021  | 

First things first, the Esprit arrived with some cosmetic damage that appeared to have been caused at the site of manufacture. (The screws to secure the dew shield had caused some unsightly marks/scrathes on the OTA from the store position for the dew shade). As always with FLO, help and a remedy was immediately to hand. Turns out that a batch had issues with the securing screw pushing the felt onto the OTA. A liberal dose of lens cleaner applied with cotton buds worked the residue loose and it cleaned up perfectly.

I purchased the Esprit mid-summer only in anticipation of long delivery dates due to demand and the pandemic effect on supply and to be ready for autumn. First light was some lunar work and the arrival of Jupiter in the early morning sky. The Esprit is a superb performer. Beautiful, crisp images despite the sky never being completely dark at this time of the year. Sitting on an EQ6-R mount I cant wait to get going on some proper imaging once astronomical darkness returns. The OTA is solid and surprisingly, and satisfyingly, robust. The focus and fine focus wheels really do allow for precision focussing and even without being locked the focus doesn't drift. I'd done considerable research on a OTA for imaging and I'm pleased to report that I am delighted I opted for the Esprit. Is it expensive? Depends on your wallet, however with this instrument You get what you pay for. Highly recommended. As always full marks to the staff at FLO who played their part in the decision process based on knowledge and experience rather than just making a sale.

Esprit 100ed… Superb at First Light
Monday, 21 June 2021  | 

Finally got first light with my new Esprit 100ed and it didn’t disappoint… coupled with my ASI1600mm Pro it produced smooth details, no vignetting and pinpoint round stars all the way to the edge (I have a Skywatcher field flattener fitted)… This is a solidly built OTA and the focusing system is also great… Wholeheartedly Recommended

FLO team is amazing

I rarely post comments on the Internet. But here I feel it's my duty to do so.

I purchased this scope a couple of month ago, the whole process was flawless. I then purchased a focus motor and had some issues installing it. So I contacted FLO. They answered right away and solved my problem in a very short period of time. They actually sent me, free of charge, a replacement piece. Turned out, it was not the piece the problem but me...

Anyway, support like this is very rare and I want here to congratulate them for it.

Keep it this way FLO.

Thanks Alex and Andy !

Steve, a very happy customer.

Fantastic image quality
Thursday, 14 January 2021  | 

I bought the Esprit 100ED only for imaging and the results from the first imaging run were jaw dropping good. The scope is my first 'quality' refractor, married to the field flattener and an ASI 1600MM-Pro the narrowband and RGB images are clear and sharp, suffice to say it is exactly what I wanted from a scope.
FLO's service was great as always.

Top Quality Scope
Sunday, 18 November 2018  | 

I already had a Celestron Edge but wanted a traditional style scope too. When I bought this it was on good advice from FLO. I am only a beginner but like nice stuff. Lol. Excellent carry case for a start. I am happy to transport this anywhere in the case. The whole setup shouts quality and care. Superb finish, mechanics and glass. It was a good 2 weeks before I had a sky to try it and Oh man, I was impressed with the views. Seeing the Andromeda Galaxy for the first time was heart stopping. Lucky for me though it started again and I had an excellent evenings viewing. Jupiter looked like I could touch it. My Celestron AX mount didn't have the correct dovetail but I bought a Vixen dovetail and go an engineering company to drill and tap it correctly so it all fits. FLO were good with advice on these parts too.
A brilliant scope. Once I get a season of observation under my belt I can start using a camera with it.

Superb Packaging !!!
Monday, 27 August 2018  | 

Lets start with this , because actually is the first thing you observe .....Everybody knows that triplets needs to be handle with extra care.......

I was worried because i live in Athens - Greece , how DHL will handle the scope etc...

When the scope arrived and had the chance to open it , i never though that this kind of packaging exists !!!
You name it !!!!

Box in another box , filled with pallet style carton box , with foam legs , with small anti vibration balls around the scope !!!!!!!!and all this inside a heavy duty black suitcase !!!!!!!

Everything intact !!!!!!!!!

Thank you .
