OVL

Progressively dims the view when observing the Moon or bright planets whilst increasing contrast, reducing glare and increasing the amount of detail to study. 

High quality CNC machined 10:1 dual-speed focuser

A high quality CNC Machined 10:1 dual-speed Crayford focuser.

The O-III narrowband filter is specially designed for the observation of gas and  planetary nebulae.

Has a 1.25" nosepiece, threaded for standard filters on one end, and an M42x0.75 T-mount thread on the other.

Comprises 4 x high quality glass colour filters.  

2" 45 degree erecting prism!

Designed to fit into a standard 1.25" eyepiece tube.  

Blocks night glow and airglow, sodium and mercury emissions (but not UV or IV). 

A Low Profile CNC machined 10:1 dual-speed focuser designed for Newtonian Reflector telescopes of 9" to 15" aperture, and accepts either 1.25" or 2" eyepieces. 

Superb quality, non-focal reducing Field Flattener optimised for DSLR imaging on refractor telescopes with focal ratios of between f/5.5 to f6.0.

This high performance CCD filter transmits only the Hydogen Beta emission line, and therefore is useful for greatly increasing the contrast of objects that glow in the corresponding region of the spectrum, for example the Horsehead, Cocoon and California nebulae.

A high-performance zoom eyepiece of top quality construction, providing a flat field of view and crisp, clear distortion-free images.

This 1mW red laser collimating device boasts some of the best and most practical functions collimators can offer. 

These contrast-enhancing filters are designed to block out the wavelengths of light emitted by mercury-vapour light and other common causes of light pollution. 

Designed for use with DSLR and CCD cameras, this low profile Off-Axis guider is a convenient alternative to using a separate conventional guide scope for astrophotography, offering several advantages. 

The Twist Lock  Adaptor is an innovative 2″-1.25″ low-profile helical self-centering eyepiece adaptor, of metal construction, threaded to accept standard 2″  filters. 

The narrowband UHC filter isolates the two doubly ionized oxygen lines (496 and 501nm) and hydrogen-beta line (486nm).

Premium x3 Barlow Lens consisting of four lens elements.

Designed for roof prism binoculars with a narrow inter-objective distance

For Sky-Watcher models with Direct SLR Camera Connection
