I would like a telescope I can use with my Canon EOS 7D DSLR and laptop. I’m looking for longevity rather than low cost, perhaps something upgradable. Any suggestions?
Steve says: “A good quality imaging telescope requires a good quality mount to support it and if you want this to be a one-time-only purchase then you should aim for a heavy-duty mount with excellent tracking abilities for future proofing.
Mounts that would ft this bill well would include the 10 Micron GM1000 HPS, the Mesu Mount 200 and the Paramount MyT. Any of these mounts will stand the test of time and never require upgrading.
For longevity and reliability, it is difficult to beat a good refractor as they don’t require collimation.
The Sky-Watcher Esprit 150 ED Pro or the Tec 140 with a suitable field fattener would be excellent choices but you could also consider the Takahashi FSQ-106ED which doesn’t require a field fattener because of its modified Petzval design.
Upgrades would include focusers although a more suitable cooled camera should be high on your shortlist.
Email Steve your astronomy queries to email@example.com and they could be answered in a future issue of BBC Sky at Night Magazine.
