Hello everyone:hi:


For sale GSO 6RC $1000

Here is what is included:
Scope
AP CCDT67

3D bahtinov mask

3D dew shield
Bob's knobs
Takahasi collimating scope with 2"sleeve and coupling
Laser collimator

Vixen dovetail top and bottom
Losmandy dovetail secured to bottom Vixen (removable)
William Optics Zenitstar 66ED guide scope with dovetail clamp
Celestron 1.25" diagonal
The scope is flocked after I've removed the rings. Seen it on the net, dose rings do no good regarding stray light management, but guiding thermal currents into the light path.
Also installed a 3D printed insert to the main baffle to prevent stray light.
It is a f9 system, so a reducer is recommended. Like the AP CCDT67.
I haven't used it for years, but it appears the collimation still OK. The included TAKAHASI collimating scope will help to refine it anyway.


PM if you interested.
I don't have original box for interstate shipping, so local sale only.


Cheers,
Mik

I forgot, happy to trade/swap for a 6" achromat like the TS 152/900, or a equivalent Fraunhofer doublet.


Regards,
Mik
