Thank you very much Astro_Bot for your comprehensive reply
very helpful. Good to know what you are using and what it is capable of.
Chris, budget is around $250, if that is reasonable.
My obs it pretty low tec at the moment (just a shed on some wheels) so I like the idea of a laptop that I can bring inside. I don't have a GoTo mount, although hopefully I will be able to build one in the near future. The computer will mainly be used for guiding and running a DSLR. Not worrying about plate solving for a few years yet
.
My obs it over 100m from the house (has ok wifi connection) so I was hoping I might be able to use remote desktop to check on guiding ect, from the house computer.
I wont be doing any processing on it.
Cheers
Jo
