Celestron 93444 overview

  • 1Description

Ideal for observation and astroimaging, the Ultima Duo 10mm Eyepiece from Celestron contains fully multi-coated optics engineered with eight lens elements arranged in five groups. Working in tandem with blackened interior edges, its optics produce bright and clear high-contrast images with true color rendition across its wide 68° field of view. Its unique snout design allows it to be used in both 1.25" and 2" drawtubes and accessories without requiring adapters. To enhance visual observation or image capture, the eyepiece barrel is threaded to accept most standard 1.25" astronomical filters.

The eyepiece has as impressive 20mm eye relief with a fold-down rubber eyecup that allows the user's head to be pulled back from the eyepiece to reduce contact and vibrations for easier and clearer observation. For astrophotography or imaging, when the eyecup is removed, standard 42mm T-ring threads are exposed to accept optional camera-specific T-rings to easily mount your DSLR or imager directly to the eyepiece. Celestron made the eyepiece out of a lightweight and durable aluminum alloy with a protective matte anodized finish, and rubberized grips for sure handling in the cold or when wearing gloves.

    Celestron 93444 reviews

    Ultima Duo 17mm Eyepiece (1.25"/2") is rated 4.3 out of 5 by 3.
    Rated 5 out of 5 by from Celestron Ultima Duo 17mm eyepiece I've used this eyepiece with an 8 Meade SCT for visual work and short-exposure astrophotos. The eyepiece performed flawlessly, giving a large field of view with great eye relief and a flat field right to the edge. The image is very sharp and bright. It couldn't be easier to take photos: just screw a T-thread adapter to a DSLR, then screw the eyepiece to the adapter and you're ready to take great photos. I'm already thinking of getting a second one in that series...

    Rated 4 out of 5 by from Nice option for DSLR astrophotography Nice eyepiece: Clear, but the eye relief is not great. Allows for direct connection of a DSLR to your eyepiece (needs appropriate adapter for your DSLR).
