The famous 10" Truss-Tube design Ritchey Chretien telescope from Altair Astro with new "version 2" split rear focuser backplate and mirror cell support structure.

Q: What are the Benefits of truss tube design vs. normal tube?

- a more rigid triangulated carbon fibre truss system is more rigid than scopes with a metal or carbon fibre outer-tube

- the open design promotes air-flow around the optics for faster temperature equalisation contributing to sharper images (a shroud is included which allows air to circulate freely, but prevents dust and extraneous light)

New 2014 edition v2 features and included accessories:

The version 2 has an improved mirror support and alignment system, allowing the focuser to be independently collimated relative to the optical and mechanical axes of the scope
New - includes a 12v dew heater for customers to install on the secondary mirror. (Works with dew controllers with a RCA socket, such as Kendrick).
New - included a new finder scope mounting bracket
New - includes special cross-weave synthetic shroud, seamstress-made in Norfolk allowing good airflow, whilst blocking out stray light and dust **
Included standard focuser able to carry a medium size CCD camera with filter wheel or OAG, or a DSLR
For heavy cameras and filter wheels, you can upgrade to a Starlight Feathertouch 3.0" Rack 'n Pinion Focuser in the dropdown menu when ordering
A set of fuzed-quartz optics with enhanced 96% reflective coatings and a silicon dioxide (Quartz) protective overcoat (see notes about coating below*)
Includes 3x rear 12v cooling fans, which can be powered by a small 6x AA battery pack, or better still, the 12v DC outlet on your Kendrick Digifire Dew Controller, or your own power source via any 12v DC power port - such as found on the iOptron CEM60 mount dovetail clamp.
Includes 2x Losmandy plates top and bottom provide a rigid and stable platform, and you can mount a guidescope on top
2x 25mm and 1x 50mm extension ring fitting between focuser and OTA to adjust backfocus (the 3x tubes when stacked give total 100mm spacing) **
Weight approx.: 14.9kg bare OTA without focuser and 15.9kg with 3" Crayford focuser.
Optional 63mm field flattener and adapter kit available with adapters depending on your camera backfocus (standard is 17mm) - please contact us for details.
Recommended, cameras, mounts and accessories: Combine the Altair Astro RC250-TT Truss Tube Astrograph with the advanced iOptron imaging mounts, and an Altair Astro Heavy Duty Portable Field Pier, or Altair SkyShed 8" semi-permanent pier, and you have an affordable imaging system which is way ahead of the curve at a reasonable price. For camera choice, we recommend the Starlight Xpress Trius range of cameras, especially the SX-35C, SX36-C, SX-26C SX-25C, SX-16. Another interesting camera to consider is the new Opticstar DS-616C XL with Sony ICX413AQ sensor. The Altair Astro 60mm and 80mm autoguiders are also highly recommended if you don't want to go down the OAG route for a smaller optical train. Please contact us for an individual consultation for all the accessories you need to get up and running.
