This ed apochromatic optical doublet tube is particularly suitable as a multi-purpose astrograph thanks to its undisputed optical and mechanical qualities. The skywatcher evostar ed100 also offers excellent visions of the moon and planets, thanks to the high contrast and sharpness offered. The f / 9 focal length, combined with the 100mm diameter, make the sky-watcher 100ed a fantastic companion for high-resolution observations of planets, moon and double stars. The possibility of reducing it with a dedicated flattener 0. The 2″ crayford focuser with 1:10 reduction gear offers a high load capacity unit with excellent resistance even in the case of heavy loads. M56 external thread for use with third-party accessories or for the connection of the dedicated reducer / flattener. For astrophotography you can decide to reduce it using the dedicated 0,85x flattener / reducer cod. Aorid085-100 or use it as native focal. Equipped with a 2” dielectric diagonal treated with a high reflectivity multilayer coating. In this way the actual reflection is 99% (normal diagonals generally reflect about 90% of the incident light). Includes adapter 2 “-1.25” with self-centering ring. Threaded to accommodate 2 “filters. The equipment is completed by a 2” let 28mm eyepiece, a comfortable 8 × 50 finder with mini-vixen base, rings and dovetail bar type eq5 and an aluminum suitcase made to measure all accessories.

Make your focusing for astrophotography an easy and magic task. About Bahtinov mask The Bahtinov mask is a device used to focus small astronomical telescopes accurately. It was invented by Russian amateur astrophotographer Pavel Bahtinov in 2008. Accurate focusing of telescopes and astrographs is particularly of concern to those involved in astrophotography. The telescope is pointed at a bright star, and a mask is placed in front of the telescope's objective (e.g. primary mirror). How does it work? Set up your telescope and imaging equipment as normal. Then simply locate a bright star (maybe Spica?) with your telescope, attach the Bahtinov mask to your telescope and watch the diffraction spike pattern around the star as you adjust the focus. When the middle diffraction spike is centered in the outer spikes, you're in focus. Very little focusing travel is required to move the inner diffraction spike, which means the focus is extremely accurate. Program type> Suitable for telescopes for Dew Shield or Front Outer Diameter From 75mm -114mm (2.95inch - 4.5nch) - For 80mm, 100mm, 102mm ED Skywatcher and Other Refractors Package Include: Bahtinov Mask 3 X Brass bolt P.S:

Sky-Watcher EQ3-2 Pro GOTO German Equatorial Mount Product Info Sky-Watcher offers simple solutions for users who would like to attach their smaller telescope to a convenient computerized system but do not wish to deal with the weight of the HEQ5 or EQ6 mount. The EQ3 Pro mounts use the same Go-To system found in the HEQ5 and EQ6 Pros-- SynScan. It allows you to point the telescope at a specific object or even tour the skies at the touch of a button. The EQ3 Pro mounts are the perfect instrument for novice visual observers to enjoy astronomy with minimal setup time and in-depth knowledge of the night sky. Features of SkyWatcher EQ3-2 Pro GOTO German Equatorial Mount: Positioning Accuracy up to 1 arc minute. Accuracy enhanced by software collimation error (mount mechanical error) compensation. Stepper motors with 1.8?? step angle and 32 micro steps driven. Slewing speed up to 3.4??/sec (800X). Guiding speed selectable from 0.25X, 0.50X, 0.75X, or 1X. Object database containing complete Messier, NGC, and IC catalogues. Periodic Error Correction. PC compatibility. Upgradeable hand control via internet download.

dovetail clamps and rail suitable for Vixen GP compatible systems The Starway VC4 is e.g. suitable for: Vixen GP2, GPD2 Meade/Bresser Mon2, LXD75, Celestron CAM - Advanced Mount Goto Skywatcher EQ3, EQ5, HEQ5 and EQ6...and for all mounts equipped with Vixen GP dovetail receptacles Side-by-Side mounting is, compared with piggyback systems, the more stable option. It's e.g. recommended to fix a big finder, a guide scope, a camera... parallel to the main telescope Technical details -- Material: Aluminium -- Weight: approx 940 gramms -- Width: 37.5cm -- Centre-to-centre distance of the dovetail clamps: 23cm With the side-by-side mount, the payload's balance point is closer to the mount. Additionally, the tube rings of the main telescope have no additional stress caused by a piggyback system.
