Read more about this feature-packed Sky-Watcher Esprit 100 mm ED APO Triplet Refractor below.
Top-Notch Optics
As an APO triplet refractor, three air-spaced, fully multi-coated correcting elements are fitted within the telescope to deliver sharp, high contrast views with intense clarity. Two pieces of Schott-BK-7 glass and one piece of FPL-53 ED glass eliminate color fringing for optimal color correction. Also, each element is fully multi-coated with the Sky-Watcher Metallic High-Transmission Coatings™ (MHTC). Internal knife-edge baffling greatly reduces stray light and reflections from bright stars, further enhancing performance! With a focal length of 550 mm and 100 mm aperture, this refractor nicely frames a wide variety of objects within the field of view.
High Precision Focuser
Furnished with a robust 3.4” Rack & Pinion focuser, smoothly adjust focus for perfectly round stars. The Helinear track design of this focuser greatly reduces image shift during focusing to help dial in on the precision. As a dual speed focuser, first find rough focus with the larger knob, then hone in on the details with the smaller, more precise knob. The high quality craftsmanship is able to handle heavy imaging equipment with ease, reducing flexure and improving image quality. Also, this focuser is fully rotatable, providing you with the flexibility of framing your targets.
DSLR Attachment
To make attaching your DSLR a breeze, Sky-Watcher has included everything you need to get you out an imaging in no time. Please note: the included T-ring is designed for Canon DSLRs. If you have another brand of camera, you will need to purchase a camera-specific T-ring for proper attachment. The steps to attach your DSLR are as follows:
(1) secure the drawtube adapter to the end of the telescope, (2) attach the field flattener to the adapter, (3) screw on the extender tube to the field flattener if not done so already, (4) add the T-ring to the extender tube, (5) finally, attach your camera, and you’re all set!
Dedicated Astroimaging Camera Attachment
To reach proper focus, your camera’s sensor must be set at a distance of 63 mm from the last lens element of the field flattener. This 63 mm of backspacing distance is easily achievable with today’s most popular user-supplied spacers and/or accessories. Important note: The telescope side of the field flattener houses 66x1 male threads, meaning you will need a spacing element with female 66x1 threads. The steps to attach your dedicated astroimaging camera are as follows: (1) secure the drawtube adapter to the end of the telescope, (2) attach the field flattener to the adapter, (3) add your user supplied accessories/spacers and camera. You’re now ready to image!
Extras That Elevate
To enhance your Sky-Watcher Esprit experience even more, a variety of optional accessories are available for add-on. When it comes to astrophotography, sharp stars are a must, which is why the team at Apertura worked hard to deliver their line of Bright Focus Masks. These innovative focus aids have been specifically designed to fit their respective apertures, which results in better, more precise focus! If you’re looking to completely automate your focus routine, the ZWO EAF is a great option. This device is to be installed on your refractor’s focuser, and with the help of software, finds the exact focal point of your optics. While the native f/5.5 focal ratio of this Sky-Watcher Esprit 100 mm APO is great for capturing lots of detail in a short amount of time, the Starizona Apex-ED 0.65 Focal Reducer takes this refractor’s light gathering speed up a notch by offering a faster focal ratio of f/3.57. This is perfect for those looking to complete their imaging projects in a more timely manner, and for those looking to widen their field of view!
