For sale is my GSO RC 10. I've used this scope for several years for astro-imaging and found it to produce very satisfying images. I've since upgraded to a larger aperture and it's now surplus to requirements. It's a versatile scope which can be used at the native f/8 or at f/5.5 with a suitable focal reducer. Used with a barlow yields good planetary images. I don't have the original packaging so would prefer pickup from Campbelltown in Sydney.
Asking $1100 which I think is a bargain.
