Thanks for the info Brendan.
I will post updates as I start finalizing the design and start the build.
For the primary mirror would anyone know if the Orion optics standard grade mirrors are comparable, better, worse than the GSO's?
any other recommendations for sources of decent primary mirrors for imaging? I'm not looking high end and don't have a massive budget, but something that will yield good results.
My objective is to keep this portable, so weight savings anywhere would be beneficial.
I remember coming across some hollow cell mirrors. not sure how good they are.
