Astronomik UHC-E Canon EOS APS-C Clip Filter


The UHC-E filter is Astronomik's low-cost option for deep sky emission nebulae and comet observation in heavy light pollution. This filter is especially fitting for smaller instruments. With the UHC-E filter, contrast of emission nebulae and comets is enhanced while street lamp light, as well as skyglow, is blocked. Optimally suited for up to 5" (125 mm) aperture telescopes.

A 45 nm FWHM (full width at half maximum) is provided by this Astronomik UHC-E filter. It highlights the contrast between your target object and the night sky, but less so than that of the UHC filter. However, the amount of starlight transmitted is larger. Thus the UHC-E filter is a better fit for smaller aperture telescopes.

Astronomik Clip Filter System


Astronomik's patented Clip-Filter system has been designed from black anodized aluminum and laser-cut on up-to-date modernized machines. Within seconds, it can be introduced directly into the EOS camera body. No adjustments are required and all lens functions like focus, screen, and image stabilization, remain operational! With the exception of the EF-S series, all Canon system lenses plus all M42 and T2 lens adapters are usable with the Astronomik Clip-Filter system. This Clip-Filter also serves as an effective dust protector, keeping dust from collecting on the sensor during extended exposures.
