TS-Optics GSO 10" f/12 Cassegrain telescope 254/3048 mm OTA - Photos included
Proven Preformer - see attached images
I really do not want to sell this OTA, however, I purchased two CFF Classical Cassegrains and I cannot justify keeping all these OTAs. This telescope produces incredible images of the moon and planets, and it works well with a ZWO ASI174MM camera. Also, a ZWO ASI1600MM captures incredible mosaics of the moon, and would be ideal with a 2u pixel size camera.
I have the original shipping box and packing material. Inquire about the shipping cost to your region, the box and OTA will ship via UPS ground. You are also welcome to pick this up from the Casper Wyoming region. For a small fee, I'm willing to meet someone within a reasonable distance from Casper Wyoming. I could easily meet someone in Laramie WY or Cheyenne WY, or northern Colorado.
I also have a cloth light / dew shield for this telescope, which is not shown, but will be included with the sale.
I have an upgraded Starlight Instruments focuser for it, and the cost was $1061,will sell the focuser with the OTA for $800 extra, otherwise the original focuser is included.
Any finder scopes, mounts, cameras, etc shown in the photos are not included. This ad is for the sale of the OTA only, but it does include all the original accessories in the original shipping box.
These are impossible to find, all are sold out, and the few that were produced are held by their owners.
