Hi Simon,
Thanks for your reply. Sent you a PM too.
Yes, I have a 10" f/5 Parks mirror I want to exploit. That is why I'm looking for a 10" tube with optics that may not necessarily be in great condition so I can reuse the tube. I am at the concept stage at this time, looking at different design options, including maybe reworking the primary and secondary assemblies of my very first DIY scope I have the mirrors in. With the total rebuild solution, I am looking at a few different ways of doing things.
HOWEVER, there is another option that could be looked at if the optics in an offered OTA are in good nick -
would anyone be interested in that set of mirrors? I can have the tube and you can take the mirrors...
Exploring options
Alex.
