Telescopes - I've owned at least a dozen. I presently own four -
a 4" Meade ETX 90
an 8" Celestron SCT
an 8" Dobsonian -and the monster light bucket
13" Coulter Odyssey 1 - a Dobsonian.
I've done street viewing, I've done specific event for whole schools and school districts and I've been asked this question a million times.
First off,
@TommyG why do you want one? Whats the purpose because they vary based on reasons for buying one.
If you want to look at different things occasionally and want ease of use - a Dobsonian - hands down. You can find a 10" Dob on the used market for only a few hundred dollars - maybe as little as $200 for a really decent used scope.
BUT - the downside is while its point and shoot - meaning you see it - and you point the scope at what you want to see - its not motorized so its drifts - its not a major hassle - I've never found it to be - you just nudge the scope - wait for it to settle down again and then it moves again.
The other
BUT with a dob is that if you can't see it easily [ such as the Andromeda Galaxy, M13 in Hercules, M42 in Orions belt, etc] then you need to know where it is and star hop to it. This means you need to know the sky. And the way to learn the sky is to sit outside with a pair of binoculars and look around - learn the constellations - and learn where things are. This takes time - and it seems most of the interesting things to see are in the winter sky - which means you're sitting outside - still in a chair in the cold. It's also cold at night in the summer - which will surprise the heck out of you.
Second - a lot of people have recommended you buy a GOTO scope - which is all well and good - but you need to know how to set it up properly = my Meade ETX is a GOTO type scope and I know the sky, I know the names and places of the stars they want you to use to set up the stupid thing - and it still takes 15-20 min just to get it set up.
Sure- there are GPS options now - but they are $2000? or so. That's prob more than you wanted to spend.
If it takes 20 min to set up a GOTO scope - you're NOT going to use it very often. While I have a very nice 8" SCT and the 13" light bucket that gets me color in the Orion nebula - theyre all a pain in the rear to set up - I can get the SCT set up in 5 min because I know how to polar align it fast - but the 13" Dob takes forever to cool off to get good images and it weighs a ton - SO - if I just want to go out and see something I'll pull the 8" DOB out. Ease of use is definitely not overrated.
So - cost:
I bought my Meade ETX used on Craigslist - I drove 2 hours to get it for $100 - a steal.
The Celestron 8" I also bought used - also $100 about 8 years ago. Needed to tweak it a little but its set up perfect now -
The Coulter scope I bought 25 years ago - they're now out of business and I paid $600 for it = and the 8" Dob I bought used at a Pawn shop for $125.
No reason to spend a lot if you just keep an eye out . . .
BTW - any binoculars bigger than 7x50 or 10x50 will weight a ton - you'll need a mount, or a harness for your shoulders - or a monopod -
