This secondary spider is manufactured on a modern CNC machining center. The high precision manufacturing ensures that the 1.8mm thick struts of the spider are perfectly aligned and the diffraction induced spikes on bright stars appear razor sharp.

Controller for Flat Field (all models)
This handy device allows the management of the Geoptik Flat Field Generator via cable or via Bluetooth.

IDAS Night Glow Filters enhance the contrast of astronomical emission nebulae against a sky with both man-made and natural* sky glow sources, yet preserve color balance of broadband objects such as galaxies.

Introducing Meade’s Series 5000 Premium Wide-Angle (PWA) Eyepieces. These high-quality eyepieces feature a fully multi-coated optical design with premium-grade, exotic optical glass for the best possible image correction in color, contrast, and brightness.

L-eNhance provides an economical and practical solution for amateurs. It is a dual-band pass filter which has been designed for DSLR (digital SLR), color CMOS and CCD cameras.

Dual Motor Focus brings a decade of experience in astrophotography and telescope focusing concepts. The evolution of technology in astronomy requires a system which will assist the focusing of the telescope with great accuracy.

The StarShoot G3 makes astrophotography of faint nebulae and galaxies affordable for those on normal incomes. No other camera in this price range has regulated thermoelectric cooling (Peltier).

These high quality filters are type 2 glass which means you will see an orange/yellow view of the sun. These filters are designed for observing sun spots.

These high quality filters are type 2 glass which means you will see an orange/yellow view of the sun. These filters are designed for observing sun spots.

It is safe to view the sun through this filter directly or mounted on a telescope, finder, spotting scope, etc. 99.999% of the sunlight is blocked. The aperture is made of a high quality, reflective coated glass and mounted into an aluminum outer cell.

All New Camera Angle Rotator for 3” M92 Focuser

Fits :
GT102, GT153, FLT132 and all other brand Focuser with M92 threads.

This kit replaces the factory spur gear drive train with timing belts. The pulley modification reduces the spur gear errors that are typical and therefore reduces tracking errors. The belts also make slewing much quieter eliminating the 'grinding' noise that the standard spur gears produce.

This Astronomik OIII-CCD Filter is suitable for imaging of OIII nebulas from observation sites with light pollution and from dark sites as well. The contrast between an object glowing at 501nm and the background is increased enormous!

Celestron are innovators and they have reinvented the manual telescope with their new StarSense Explorer range — the first telescope that uses your smartphone to analyse the night sky and calculate its position in real time.

A high quality CNC Machined 10:1 dual-speed Crayford focuser designed as a direct replacement/upgrade for the rack & pinion focuser supplied with the Sky-Watcher Evostar-102/120/150, Startravel-102/120/150 and Evostar-80ED/100ED/120ED Refractors.

Narrowband filters are used to create high contrast deep sky images of certain objects, mainly emission and diffuse nebulae (i.e. Veil Nebula, M42 Orion Nebula, North America Nebula, Horsehead Nebula) or planetary nebulae (i.e. M27 Dumbbell nebula, M57 Ring Nebula, Helix Nebula)
