The target chosen for first light was NGC 7635, which was chosen for its spectacular detail in both narrowband and broadband spectra. I got my Sky-Watcher Esprit 150 ED PRO Triplet second-hand but literally in "NEW" conditions, My first impression is WOW that is really a big telescope, the build quality is great and it feels solid and well constructed. Connect the triplet and doublet field flattener with a high precision thin thread to keep the optical axis perpendicular to the image. Photo courtesy of: Nik Szymanek. I've used it with my ZWO and stars are in focus edge-to-edge. "...offers strong competition to the established refractors from Takahashi and TEC." It wasn't that it was loose, it was missing. I was lucky enough to have access to the new SkyWatcher EVOSTAR 150ED-APO for the 2018 planetary season over several months. This new apo refractor provides premium performance . The scope case also was excellent with wheels and handles. It lies close to the direction of the open cluster Messier 52 which can be seen in this image upper left. The Sky-Watcher 150mm Esprit 150ED Triplet APO Refractor is a professional instrument for the most demanding and exacting astro-photographers.The air spaced apochromatic triplet lenses use the remarkable Ohara FPL-53 ED (extra low dispersion) glass, with exceptional colour correction over the entire visible spectrum there is no chromatic aberration even on bright objects! Submit Review. at a premium price. This is the latest project of observatory director Terry Hancock, and all images were captured from the Grand Mesa Observatory in Western Colorado. The premium optical materials used in this telescope include an objective lens with FPL-53glass. Esprit 150ED F7 Professional Triplet Refractor £ 3,998.00 The ESPRIT Super Apo Triplets are designed for the most demanding astro-imagers but are also fine telescopes for visual observations. The selected triplet lens offer perfect images even at … ...Focusing was fast and easy and the whole procedure became second nature." I also like how much comes with the scope (rings, dovetail for mounting, dedicated field flattener, 2” diagonal, eyepiece, a very heavy duty case with wheels and handles, etc). DESCRIPTION. The ESPRIT Super Apo Triplets are designed for the most demanding astro-imagers, for use with the optional M48 field flattener, but are also fine telescopes for visual observations. A Second Dome for the Grand Mesa Observatory! When used with the field flattener the Esprit-80's imaging circle is 33mm.

Start Chat Esprit 150ED Super APO Triplet by Skywatcher Esprit 150ED Super APO Triplet. I’m very impressed with the Sky-Watcher 150 Esprit, using the big chip QHY16200A CCD Monochome camera with an OAG the Esprit 150 gives a very sharp image and a nice flat field, (Sky-Watcher quote a 43mm image circle), although a little slower than the TAK130, image quality is superb and unlike many APO refractors I have owned or tested the Esprit has a dedicated Field Flattener/corrector.
