• Green Witch

This Premium Woven Polyester Telescope Cover is specially treated to protect against snow, frost, rain, pollution and birds. What's more, it is ultra violet-stabilised to protect against the harmful effects of sunlight and its Weather-GardT protection means it is 100% waterproof.

Integral ventilation flaps make it especially suitable for protecting a telescope. Solid brass eyelets and quality tie-cords are provided, and every cover comes complete with a durable zip-up storage bag.

Use the cover to protect your telescope while you wait for the weather to change or when you don't want to take it in until the next day. Equally useful as a dust cover for indoor storage.

The top picture shows it on an 8-inch Dobsonian but it is big enough to cover a 12-inch SCT such as an LX200.

The bottom picture shows it protecting a C11 OTA mounted on an EQ6. Guess where it is then click the 'more' button to see if you are right.

House martins are the birds with white rumps that build mud nests on the eaves of buildings, often in colonies averaging five nests. They will readily use artificial nests and this may encourage other birds to nest nearby. These nests should be sited underneath the eaves of your house or outbuildings.

AstroSolar film has become the natural first choice for white-light solar observation. Its optical qualities are excellent, enabling you to see high-resolution images with a natural colour. It is tough and durable, very difficult to tear, but cuts easily to make the shape you need. Use it with confidence on telescopes, binoculars or camera lenses. Comes with full instructions for using 'Blue Peter Technology' to make a removable solar filter.

The filter will allow you to observe sun-spots, surface granulation, limb darkening and faculae.

The Star Analyser 100 is a high efficiency 100 lines/mm transmission diffraction grating, blazed in the first order. It is mounted in a standard 1.25 inch diameter threaded cell, to be compatible with most telescopes and accessories.

It complements a wide range of types of camera used in astro-imaging. It can however also be adapted for visual use. A locking ring is also supplied to lock the grating in the desired orientation.
