When you need a secure way to attach a CCD camera at the image plane of a CDK telescope, the Secure Fit Spacers get you the optimal back focus spacing. These spacers attach via four screws to the PlaneWave Hedrick and IRF90 Focusers.  When coupled with a PlaneWave SecureFit CCD Adapter, they practically eliminate slippage, movement, and equipment drops. The spacers come in eight different lengths: 2.1″, 3.8″, 4.5″, 5.2″, 5.9″, 6.75″, 7.5″, and 8.25″.

These spacers are made for the CDK14, 17, 20, and 24 and do not work with the CDK12.5.  The CDK12.5 Secure Fit Spacers have a different bore size.

The UHC-E Filter increases contrast of emission nebulae and comets and blocks the light of typical streetlights as well as airglow. It is best suited for telescopes up to 5" / 125mm.

Main use

The Astronomik UHC-E filter provides a FWHM of 45nm and blocks the light of typical streetlights (e.g. sodium and mercury vapour) as well as airglow. Thus it increases contrast between your target and the night sky. The contrast enhancement is less than that of the Astronomik UHC filter, but at the same time the transmitted amount of starlight is greater. It's therefore better suited to smaller telescopes. As the UHC-E filter passes a spectral line of Carbon (due to the higher FWHM) it opens up the possibility of comet observation.

Other uses

• Observation of Jupiter’s clouds.
• Easier resolution of Double Stars.
• Photography under light-polluted skies with DSLRs and other cameras.

Suitability

• Visual observation (dark skies): Reasonable, an UHC filter is more suitable
• Visual observation (urban skies): Good, for telescopes up to 125 mm aperture and medium exit pupil
• Film photography: Good, but very long exposure times
• CCD photography: Good, when used with an additional IR-block-filter
• DSLR photography (original): Good, colour balance is near perfect
• DSLR photography (astro modified): Good, colour balance is near perfect
• DSLR photography (MC modified): Good, when used with an additional IR-block-filter
• Webcam / Video (Planets): Unsuitable
• Webcam / Video (Deep Sky): Very good, if light pollution is a big problem
