Rother Valley Optics are proud to introduce their Geoptik Nadirus 12" f/5 dobsonian. This is a one of a kind telescope. The dobsonian kit is made to a superb quality and finish by Geoptik in Italy. The telescope is then finished by our own specification and detail.

Focal ratio: f/5
Focal length: 1250mm
Mirror size: 12"
Mirror quality: Orion Optics Ultra Grade

This amazing telescope features a superior quality Orion Optics Ultra grade 12" F5 mirror, a Moonlite dual speed focuser with shaft lock, an Explore Scientific 90° amici prism polar right angled finderscope. The Geoptik accessories included are a wheelbarrow kit for easy transportation, a light shroud and shield and levelling feet. We have also incorporated a fan to cool down the mirror before observing with a convenient battery box. Also featured are 2 Geoptik magnetic counterweights that slide up and down a magnetic bar. This makes balancing these telescopes a breeze.

We are confident in saying that this is one of the best quality portable dobsonians on the market today. It is very easy to collimate. The floating cell that holds the mirror features upgraded Bob's Knob's springs and also mirror locks for fine adjustment.

Despite the size of this telescope, it is very portable. The secondary mirror housing comes away from the main trusses to then leave the base, and primary mirror housing. The trusses are all colour coded on the base, on the truss and up to the secondary mirror housing. This means once dissembled , the telescope is incredibly portable. Once you are ready to re assemble in the field, match up the colours from the base up to the secondary housing, then tweak collimation, and you are ready to go in minutes!

This telescopes are made to order so we can use any grade of Orion Optics mirrors, any focuser and any finder. Please get in touch to discuss your requirements and needs. If you are unsure, we can always put together a recommended kit.

The accessories that we have used on this particular model are the ones that we feel will compliment the telescope the best. The ES finder with it's 90° viewfinder makes locating objects very easy and convenient. The Moonlite focuser offers precise focus everytime plus the ability to lock the shaft so you won't accidentally knock the focus out when changing eyepices. The scope also comes with an allen key to adjust the mirror locks for fine collimating adjustments.

Please note this telescope doesn't come with any eyepieces. Again, if you require recommendations, then please get in touch with us.

A complete Zyro report for the mirror is included with all Nadirus dobsonians.
