I have a Protostar curved arch spider & Protostar secondary mirror for sale. Key dimensions are:
- Spider arch fits tube ID of 10.5" to 15" (I used it on a 10" with octagonal upper tube assembly)
- Protostar secondary has 1.83" minor axis (mirror is fitted to spider).
These were bought new last year & have been in storage for six months. The secondary mirror is centre spotted (visible in the photo), but is otherwise unmarked. It also comes with the installation manual. New price is US$137 for secondary & US$104 for spider.
I will sell them both for Aus $180 shipped.
Thanks,
Phil
