UP NEXT - Choosing and purchasing the secondary mirror and spider vane. It is also about time to place an order for my Royce conical 8" F/5 primary :-D. The figuring and coating processes take place at different locations so it will be at least a couple of weeks before I can take delivery of the mirror. I'll probalby place the order soon so that the mirror will be available a few days before I'm ready for it (rather than having to wait).
