HI Neo!
Welcome to the forum! How did you hear about us?
Great to see you've done your research.. i'll answer a few questions now and i'm sure others will provide more answers.
a) Yes and yes. You can buy an EQ6 or similar motorised/computerised mount (looking at $1500+) and put the newtonian OTA on it for tracking and astrophotography. For simple tracking and simple astrophotography, you can also use an EQ platform while still keeping the convenience of a dobsonian base.
b) Yes, definitely. Get the cheshire/sight tube combo. But you can also simply use a film cannister with a small hole drilled in it.
c) Aperture wins, always. The 10" is worth the extra.
d) The eyepieces that come with the scope will get you buy, but it won't be long before you'll want some extra eyepieces (better quality ones) and also a 2x barlow. Budget at least $500 for eyepiece/barlow upgrades in the next few months.
e) No, it's no problem. But if you need glasses to observe then your eyepiece choices mean factoring eye relief as a higher priority. You'll need eyepieces with more eye relief so that they are comfortable to use and you can see the whole FOV while wearing glasses.
f) I think they're on the GSO website, someone else will provide a link. The scope won't get damaged by transportation as long as you secure it properly (don't let it roll about the back
). But collimation can be knocked out in the car, so you will need to learn to collimate and check it regularly.
g) The binos will still get some use occassionally - they'll be fine in combination with your scope. And even in light polluted skies you will see a MAJOR (and I mean, major!) difference between the binos and a 10" scope. Binos are great for widefield scanning of the milky way, but they just don't compare to what you'll see on planets, the moon and deep space objects through a 10" telescope.
I'd also recommend getting to a local observing group and looking through some similar telescopes before taking the plunge. You'll get a much better feel for what you're getting, and what you'll be able to see.
Also, it would be great if you could come to
IISAC at the end of the month - there'll be tonnes of people to help you spend some money and loads of telescopes to look through.
Good luck and keep asking questions!
