Description

Bintel GSO BT252 f/4 Carbon Truss Newtonian

This Deep Sky imaging scope utilises Carbon fiber to eliminate weight, whilst the Serrurier truss design ensures there is no flexure in the scope and all the time looking very sexy.

The serrurier truss system, first designed by Mark Serrurier whilst working on the 200″ Hale telescope at Palomar mountain in 1935 has been used to stop flexure in telescopes. It works by supporting the primary and secondary mirrors with two sets of opposing trusses before and after the declination pivot point. The trusses are designed to have an equal amount of flexure, which allows the optics to stay on a common optical axis. By having one set of trusses working against the other set of trusses ,thereby keeping the optical elements parallel to each other. This keeps the scope in collimation regardless where the scope is pointed on the mount.  The use of Carbon Fibre truss tubes eliminates the changes in focus due to thermal expansion.

The primary mirror is housed in an aluminium mirror cell. The mirror cell has six recessed collimation screws accessed from the rear of the scope.  The push – pull collimation system  holds the collimation more securely than knobs and springs. Three small computer type cooling fans arefitted to the rear cell to speed up the cooling of the primary mirror. Powered by 8 AA batteries (battery case only supplied) or can used external 12vDC power supply.

The secondary mirror is housed in a top cage with two aluminium rings, The top ring holds the secondary spider and secondary holder. Collimation is done from the front of the tube. An optional heater can be fitted around the secondary holder stalk. The bottom ring is the anchor point for the truss tubes. The hardware for holding the truss tubes is CNC machined in aluminium and uses Stainless hardware to holding all together.

The focuser is a 2″ Linear bearing Crayford design with a 1.25″ adapter both the 2″ and 1.25″ holders use brass compression rings for better centering and zero damage to expensive cameras and eyepieces. There are two course focus knobs and on one side there is a smaller Black fine focus knob. This has a reduction of 10:1 enabling fine focus. The focuser also has two thumbscrews on the underside for tension adjustment and locking focus.  There is 51mm of travel of the drawtube and there is a scale on the drawtube with mm increments to enable zeroing focus easier with image train fitted.

Optional Coma Correctors are available in various brands and qualities, please email for details on each.

Losmandy D-Style Dovetail Bars are fitted top and bottom for mounting on mounts with D-style saddles.

An Astrophotography Powerhouse

The EQ6-R boasts a number of features to aid astrophotographers. The built in ST-4 Autoguider port turns this mount into an astrophotography powerhouse, allowing you to utilize most of today’s best autoguiders. Using the integrated RS232 port, you can control the telescope from your computer and take advantage of today’s most advanced astronomy software. With a weight capacity of 44 lbs, the EQ6-R can handily support an optical tube, imaging accessories and camera.

Silent Yet Precise Slewing

The EQ6-R Pro uses Stepper motors with a 1.8° step angle and 64 micro steps driven. Stepper motors are quieter than servo motors, providing accuracy up to 1 arc minute without waking your neighbors from buzzing motors.

42,000 Object Database

Using our proprietary SynScan hand controller, the EQ6-R Pro provides a user-friendly interface with automatic slewing to over 42,000 objects in the night sky. The hand controller can also connect to a computer using the supplied RS232 cable (USB adapter available), enabling computer control with most astronomy programs. For the astrophotographers looking to reduce Periodic Error, the SynScan hand controller has built in PEC training that can be configured while in the field!

Flexible Polar Alignment

Sky-Watcher includes an illuminated polar finderscope to aid the polar alignment process. The finderscope features a circular grid reticle for the northern hemisphere, consistent with todays popular polar alignment apps. For astronomers in the southern hemisphere, the constellation Octans is built into the reticle as well. Even without a clear view of Polaris, the EQ Pro can be polar aligned using our SynScan hand controller. Simply choose one of the visible stars listed and use the latitude adjustment screws to center it in the eyepiece.

Bundle of Accessories

As customary with all Sky-Watcher products, an assortment of accessories are included with the EQ Pro mount. A retractable counterweight bar is supplied, allowing for easier transportation as well as two 11-lb counterweights are included to help balance any payload. The EQ Pro features a saddle compatible with both D and V style mounting plates, granting users the flexibility to utilize multiple optical tubes, even if the mounting plate is different.
