Welcome to the Club Noticeboard!

As the club is newly formed we would like to take this opportunity of welcoming new club members and to say that it is hoped that this area will be an opportunity for members to use freely. It can be used to:

- Exchange information about what's happening in astronomy in and around Swindon
- Be able to offer for sale second-hand products that they no longer use
- Perhaps to exchange books or magazines that they have finished with
- Offer tips and advice on star-gazing and viewing sites around Swindon
- Seek solutions from other members on problems to do with astronomy
- Advice sought on setting up and caliberating or collimating telescopes
- Seek advice on astro-photography from more experienced members

Using this notice board is easy, all you have to do is contact the website administrator on the email link below and send your information within the email. The website administrator will then decide on the best way to display or sell your item, but if you have any special instructions as well, please include them in your email. Photographs and illustrations can also be included, preferably around 100k in size.

Set of 4 Abbe Orthoscopic Eyepieces 1.25" fitting

I have a set of 4 ortho eyepieces for sale in the following focal lengths: 4.8mm, 7.7mm, 10.5mm, 16.8mm. These ep's are manufactured by Kson based in Guangdong, China, and were offered for sale for a very limited period in the UK.

Orthoscopic eyepieces are especially good for planetary and Moon observation, however, are noted for their narrower FOV, usually about 40° to 48°, but give good clear sharp contrasty images on-axis.

This set is for sale complete only - the ep's come in plastic bolt cases and boxes.

Orion Skyglow and Light Pollution Filter

A good quality light pollution filter Catalogue No 05660, blocks typical mercury vapour light pollution whilst allowing all other wavelegnths to pass through. Packaged with transmission charts etc. 1.25" fitting.

For LOCAL sale only - £17. Contact: Robin Wilkey - Try before you buy offered!

Orion Hydrogen-Beta (H-Beta) Filter - 2"
A Hydrogen-Beta telescope filter may be the only way to see the faint and elusive Horsehead, California, and Cocoon Nebulas. It blocks everything but the hydrogen-beta light these faint nebulas emit, providing the contrast needed for viewing

By isolating the hydrogen-beta spectral line centered at 486.1 nm in a 12nm band-pass and blocking other wavelengths, Orion's Hydrogen-Beta Telescope Filter effectively blackens the background sky, allowing the faint nebula to become clearly defined. It increases contrast even under dark skies so you can visually capture these prized targets. Use with a moderate to large aperture telescope under clear, dark viewing conditions. Threaded to fit 2" telescope eyepieces and telescope diagonals.

For LOCAL sale only - £80. Contact: Robin Wilkey - Try before you buy offered!

Other 2" Filters For Sale:

Note that if you have a 2" focuser, 2" filters can be used with either 2" or 1.25" eyepieces as they can be placed anywhere in the optical path, such as on the 2-1.25" adapter or in front of the diagonal and so on!

Baader Neutral Density Moon Filter - ND96-0.9 for 13% light transmission

Baader Neutral Density Moon filters are multicoated, planoptically polished and genuinely neutral - they reduce brightness without affecting colour.

For LOCAL sale only - £25. Contact: Robin Wilkey - Try before you buy offered!

Sky Watcher Variable Polarising Moon Filter

This variable polarizing filter made from anodized aluminium and optical glass allows you to progressively reduce the amount of light entering your eyepiece.

Reduces glare whilst increasing contrast so perfect for observing bright objects such as the Moon or certain planets.

Light transmission can be varied from 40% down to as little as 1%.

Will not change the colour of the object being viewed.

For LOCAL sale only - £25. Contact: Robin Wilkey - Try before you buy offered!

Sky Watcher OIII Filter

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

The O-III narrow band-pass filter isolates just the two doubly ionized oxygen lines (496 and 501nm) emitted by diffuse, planetary and extremely faint nebulae.

O-III filters are best suited to telescopes of larger apertures and can produce near-photographic views of the Veil, Ring, Dumbbell, Orion and many other nebulae.

Effective under even heavily light-polluted skies!
