aangeboden: Celestron RASA 11-inch f/2.2 OTA + accessories -- REDUCED


Im selling a Celestron RASA 11" F/2.2 astrograph, with the following accessories:
+ Original T2 and M48 adapters (55mm back focus)
+ AstroZap dew shield a must for using a flat panel
+ Kendrick dew heater band
+ Starizona MicroTouch focuser motor and controller
+ 3D-printed cable guide for avoiding extra diffraction spikes

I have been very satisfied with the scopes optical performance, the speed is just unbelievable. But since we completed our observatory automation project this summer I need to move to a more remote-friendly setup.

Due to an unfortunate mishap with the corrector plate the scope had to visit Celestrons factory (08/2017), where it has been cleaned, regreased and collimated so the optics are in a pristine condition. It has not been used since. Only minor signs of use (see pictures).

Ive been using the scope for two seasons now so if you have concerns or questions I should have the answer for you. The first doubt everyone has "but the camera blocks so much of the aperture!!", which I consider a moot point this is not a planetary instrument. The total obstruction is still much less than with many other high-end astrographs. To avoid extra diffraction spikes from the camera I used a 3D-printed aperture mask on top of my camera (QSI690). If you tell me your camera dimensions I can print one for you, too.

High-res pictures of the scope and accessories are available here: https://www.flickr.com/gp/60049625@N03/iT4r0Q and you can find plenty of images taken with this scope from my astrobin account: http://astrobin.com/users/vehnae/

The scope and the accessories retail for about 5300 (@ Teleskop-Service), Im asking for 3300 or a sensible offer.

The scope is located in Espoo, Finland about 10km from Helsinki. It would be awesome if you can pick it up personally (ferries run from Stockholm/Tallinn daily), but shipping can of course be arranged for which I have the original packaging.
