The latest Version 3 12" Truss-Tube design Ritchey Chretien telescope with ideal optical and engineering.

- a more rigid outer skeleton using Carbon Fibre rods in a Surrier Truss configuration
 
- new independent mirror / focuser backplate supports, and independent tilt collimation
 
- Open design promotes air-flow around the optics for faster temperature equalisation and virtually no tube currents which plaque SCTs and other scopes. What's more, laminar flow currents over the optics (micro-seeing currents) are drastically reduced. The result is an amazing planetary imaging performer, despite the large secondary obstruction.

- 2432mm focal length to reveal detailed structures in challenging deep sky objects such as galaxies and planetary nebulae, whilst keeping overall weight of the optical tube very low 

- Fuzed quartz optics with enhanced 99% reflective coatings give rapid temperature equalisation *
 
- 3x rear 12v cooling fans which can be powered by batteries, a Kendrick Digifire Dew Controller 12v outlet, or a 12v DC power port such as found on the iOptron CEM60 mount.

- Large secondary to minimise vignetting which will easily illuminate a full size CCD sensor

- Centre-spotted secondary mirror for easy collimation

- Both primary and secondary mirrors can be independently collimated for the best performance unlike a Schmidt Cassegrain

- Focuser backplate can be independently adjusted for tilt, relative to the rear and front mirror cells (allowing independently tilt adjustment of the focuser).

- 3x Rear 12v cooling fans which can be driven from batteries, your Kendrick Digifire Dew Controller 12v outlet, or a 12v DC power source like on your iOptron CEM60 mount or just a battery pack.

- 2x Losmandy plates on top and bottom

- Finder mount accepting Lightwave finder bracket

- Special double layer cross-weave Neoprene shroud made in the UK, allowing good airflow, whilst blocking out stray light and dust **
 
- 3x Focuser extension rings. 2x 25mm and 1x 50mm extension ring fitting between focuser and OTA to adjust backfocus**
 
- 3" Linear Bearing Crayford focuser included as standard, able to carry a medium size CCD camera with OAG, or DSLR (for heavy cameras and filter wheels, you can upgrade to a Starlight Feathertouch 3.0" Focuser).

- 285mm back focus for any accessory including spectrographs

- Weight: 19.5kg without focuser, approx 20.5kg with standard 3" linear bearing focuser

- Optional dew heater and camera tilt adjuster available

Your choice of iOptron, SkyVision, Skywatcher or Bisque observatory mount.

* An improved surface accuracy now available with dielectric coating.

** These essential accessories are included in the price and last time we checked are worth well over £200 if bought separately. Always check.

Availability: We order these scopes each month, but sometimes there is a wait for the next shipment, because they are often presold. Click the notify when in stock button for and email update.
