Dave's Scope Guide For Beginners

 

First, we need to go over the 2 Telescope Rules:

1) Never, ever even think about looking at the Sun with a telescope or a pair of binoculars. You (probably) have 2 eyes, so you can violate this rule twice in your life. My strong recommendation is not to violate it at all!

2) Don't buy a department-store refractor. These pieces of junk show up at Sears or Wal-Mart each year, and the clue is this: They are advertised by their magnification. [675X!]. You don't want high magnification if you're starting out, and even if you did, these scopes are not really capable of delivering it.

The first place to start if you're interested in buying a scope is the sci.astro.amateur Telescope FAQ. It's a nice intro, and I agree with 99% of what's in there. If you follow the FAQ to the letter, you'll attend some Astronomy club meetings in your area, get a chance to look thru several different kinds of scopes, and end up buying a 6" or 8" Dobsonian. If you add in an extra eyepiece or two, you'll spend about $500 and enter the hobby with a good quality general purpose scope.

If you want to make one, I'd recommend starting with Richard Berry's book Build Your Own Telescope. The book (considered a classic in the ATM (Amateur Telescope Making) community) has plans for 5 scopes, I started my ATM career with the 6" f/8 dobsonian. I recommend building your own, if that appeals to you. During the time I built my first two scopes, I enjoyed the building at least as much as I enjoyed using them later. If you do not enjoy building stuff, don't try, you'll only get frustrated.

My personal recommendation for beginners who don't want to build: a 80mm widefield refractor. Orion has one, as does Celestron (They're the same scope, OEM'd from somewhere in China). They sell for $250 (at most... I've seen them for $99 at Adorama on special) and come with a couple of eyepieces (of mediocre quality). You may need to spend another $100 on a tripod (though it often comes with the scope) - so you're set for just under $400.

Why do I recommend this scope? Several reasons:

There are two things this scope will perform poorly on, compared to a 6" f/8 dob:

For the planets, I recommend looking thru a "real" scope at a star party or an Astronomy club meeting, etc. The Moon will look great in the 80mm scope, but then, it looks great in anything.

As for galaxies and nebulae, it is likely that you'll start observing from a light-polluted area (in a city). And, light pollution kills galaxies and nebulae anyway.

That's my advice - easily worth 2 or 3 times what you paid for it :-).

My background: I've been an amateur for a couple of decades, I've built 3 scopes and bought a 4th, and I've looked through many different kinds of scopes.
