Oversized tube for 10" Newtonian OTA
Hi,
I'm getting a 10" f/6 primary mirror and need some advice on how to quickly get/build a structure around it.
One option is to use the GSO 12" f/5 tube and modify the mirror cell for the 10" mirror. Can't use their 10" tube as they're f/5 instead of f/6.
Did some calculations with Newt and this seems to be a viable option (attached pics).
Other than the extra bulk, what are the disadvantages of going this route?
Thanks,
Arief
