Orion Optics 6" f11 'Planetary' Dobsonian


Recommended Posts

Looking forward to hearing your views on the curved spider Shane. Let's hope you get some clear sky over this new moon period to really give it a run out.

Beautiful looking 'scope btw. A 6" f11 would be a fairly easy self grind mirror too.....

Already done it mate. Work a treat.

I am terrible when it comes to wanting to make new things though. But a 6" planetary newt would make an ideal starter grind for someone I would have thought. Not much to grind away, and very forgiving on the figuring part.

Orion Optics UK do not advertise 150mm F11 Newtonians any more, however Teleskop Express sell the optics

. Only thing not sold for it by them is a 70 inch tube. 

If you contact OO I'm sure they will make one for you to your spec.
