    Questions & Answers

    Ask a Question
    • Hi, the CG-5 Mount plate of this tube will fit on the ioptron EQ Pro computerized mount? Thanks.

      Yes, the mount in question has a dual Losmandy and Vixen saddle plate that is compatible with the CG-5 plate on this Celestron OTA.

    • What is the difference between this OTA and the Celestron NexStar 6SE?

      The color of the tube is the primary difference, actually. The C6 optics are the same whether sold as an OTA, on the SE or Evolution fork mounts, or on the AVX EQ mount.

    • Can I use this tube with the Celestron/Skywatcher All-View mount?Or the tube is too heavy for this mount?Thank you!

      That particular scope would be too havy for proper use on this mount.

    • Hi, what mount(s) are compatible with the "CELESTRON 6 SCHMIDT-CASSEGRAIN OTA WITH CG-5 MOUNT PLATE"? Please do not suggest EQ's or computerized mounts. I am just looking for an ALT-AZ mount that has slow-motion control cables.

      For a manual alt-az mount, the Vixen Porta II mount or the Explore Scientific Twilight 1 mount will work. https://www.optcorp.com/vixen-porta-ii-az-mount-5863.html, https://www.optcorp.com/explore-scientific-twilight-1-alt-az-mount-with-heavy-duty-tripod.

    • Can this ota be mounted on a Celestron CG4?

      Yes this telescope will mount onto the Celestron CG-4 mount.

    • Hello! Can I use this OYA with the IOPTRON SMARTEQ PRO COMPUTERIZED EQUATORIAL MOUNT? https://www.optcorp.com/ioptron-smarteq-pro-equatorial-computerized-mount-3200.html Or the tube is too heavy for this mount?

      After attaching all accessories to the optical tube, it will be too heavy for this mount. You will want, at minimum, the iOptron CEM25 mount. Please contact us if you are looking for additional alternatives.

    • What is the magnification of this OTA at prime focus, when using a T-mount and DSLR? I know how to figure magnification when using eyepieces for viewing.

      The magnification is equivalent to the focal length divided by the sensor diagonal in mm for your camera. For a normal APS-C DSLR, your would use 28mm for a Canon (54x) and 30mm for a Nikon/Sony (50x).
