Entry-Level Astronomy? 358

I've always been interested in astronomy in general, and I would like to put my dark skies to use by picking up decent telescope and learning a bit about the skies over my head. The overall budget for this project is going to be around $1,000. I am particularly interested in astrophotography, but I understand that that may carry me outside the scope of the initial budget. I've already signed up for my local astronomy club's next monthly meeting. I have been doing Web research, but I thought that the Slashdot community would be the perfect place to get opinions on entry-level equipment, websites, and books."

Anyways, to the poster: First off, let me recite the standard advice for getting a telescope:
1) Don't buy from a "junk" brand (and there are a lot of them -- Bushnell, Tasco, Baytronix, etc). Get a name brand -- Meade, Celestron, Orion, etc.
2) Get large aperture, but keep the telescope portable, or you'll never use it.
3) Don't buy from Ebay.
4) Don't even buy from a store like Walmart. Buy from a telescope dealer.
5) Get quality optics like Televues and Naglers.
6) Subscribe to astronomy magazines, join a local astronomy club, and on and on.
7) If you can't afford everything above, just buy binocs.
8) Don't do astrophotography; you'll just be disappointed.
Let me tell you that most of that advice is bollocks.
Follow #1 and, as money allows, #2. Completely ignore the Ebay advice. Ebay is *wonderful* for telescopes and accessories (of course, verify that they're actually cheaper there than elsewhere before you buy, but they usually are). I find that things get to you faster from Ebay, too, and they're almost never "backordered" like so many stores are. I bought my scope, four eyepieces, and a barlow from Ebay, and everything was exactly as described, shipped quickly. One caveat: With the scope itself, if it has a motorized mount or an autostar, make sure you have a warranty. This is very sensitive scientific equipment, so Murphy's Law applies. Also, never trust an airline with *any* part of your scope any further than you can throw them, no matter how well you pad it. Trust me on this one. I've had an equatorial mount sheared clean in half by them -- i.e., straight through a bolt with about half an inch of steel, sheared right off. I think they were having a monster truck rally on top of my luggage. If you're taking a scope on the plane, the whole thing must be carryon. Let me also take this change to plug Meade's customer service, which I've dealt with several times, and have been *very* pleased with.
The "Televue and Nagler" advice is idiotic. People who advise that (and I've heard way too many) would have you spend your entire budget on two eyepieces. There are plenty of cheaper eyepieces that aren't too much lower quality than those top-of-the-line pieces. Antares eyepieces are good. I use Meade 4000 series, and have been very happy with them. On ebay, you'll only spend about $40 each for them.
Your budget is bigger than mine was, so I wouldn't recommend my scope (a Meade DS 2130AT -- a 5" newtonian with a motorized equatorial mount and autostar -- $170, plus some money for eyepieces to replace the junk ones that it comes with). You can do better than 5" aperture. I wouldn't go with a newt at all; they'll get too heavy and bulky as they scale up, and the short tube newts aren't that good. I think you'd want one of the Cassegrain or Maksutov varieties so that it'd be more portable. Perhaps something in the Meade LX series.
It doesn't hurt to join clubs or subscribe to magazines. On the other hand, you don't *have* to. There are plenty of astronomy forums online, and lots of articles.
As for astrophotography, it's not a case of "don't do it", just "do it right and be patient". One thing not to do, IMHO, is afocal with your current camera. On sites that list afocal as a method, caveats with it often are not stressed enough. If you have a fast lens, the vignetting will be atrocious, often to the point of the pictures hardly being usable. Also, the higher the magnification you use, the worse the vignetting. You really need a camera that you can remove the lens on (eyepiece projection and prime focus astrophotography). Ignore the people who say to get an SLR (non-digital). If you want to use a regular camera, get a DSLR; modern astrophotography benefits hugely from digital postprocessing. However, any camera that might be even a little heavy should

That leaves the choice of lens - whatever you buy if you decide to go the camera / tripod route invest in a really good lens - it's better to buy a $300 body and a $700 lens then vice versa since your glass has a greater impact on picture quality than MP's and you'll want fast glass (the ability to shot at faster shutter speeds in low light).

The best balance in this big_mirror/refractor conflict is an apochromatic refractor. Because - apochromatic means that the lens are covered with special layers that give about 96+% of light transmission (so it's better than non-apochromatic refractor, where some light is wasted on the lens and you don't see deep-sky objects clearly), and special layer eliminates light dispersion like in an optical prism (otherwise each color would go on a different path and the resulting picture of something looked more like a rainbow instead of beight sharp). And also as a refractor it's good for planets. But... this APO refractor has to have big aperture, or it won't work for deep-sky anyway.
Refractors have some other advantages - for instance you don't have unnecessary air flow between the lens because they are inside a tube. Newtons are much brighter (good for deep-sky) but air turbulence blurries the view on planets.
Oh, and forget about cassegrains, they are compact, that's true (the only advantage). But the view is terrible.
Well if you have just $1000 you gotta decide: (1) want to see distant galaxies (newton), or (2) view to see planets (refractor). But I suggest to spend a bit more cash and get APO refractor. Should be good for both.

Deep-sky astrophotography is expensive and for the moment, you're better served with a good visual instrument to get you started. (If you just want to take images of the moon and planets, you can get by with a webcam and a lower cost equatorial mount.)
With a $1k budget, you won't be able to do deep-sky astrophotography. Given your budget, the economics of astro-imaging, and the difficulty of putting a large telescope on a quality equatorial mount, your best bet is to forego imaging until you can save a substantially larger amount of money.

For astrophotography you absolutely *must* have an equatorial mount, it is simply impossible to do astrophotography with a stock altitude-azimuth mount, because while it can still track the sky as it moves, the view will rotate as it does so. With an equatorial mount, the view stays properly aligned even while it tracks the sky. German equatorial mount is the preferred mount for astrophotography. Even looking at just the mount you've pretty much blown your budget right there.
Secondly, you're going to want a high quality right-ascension drive motor. It's possible to get by without one, though tedious and limiting, but don't bother with a cheap one. The gearing is insufficient for astrophotography and will cause jerking and backlash resulting in awful pictures.
You'll also need to get a heavy duty mount and tripod, because a normal tripod is only designed for the weight of a telescope, not a telescope with a camera hanging off the end. You also need to make sure you've got a very sturdy, firm mount, because any vibration at all will ruin your pictures. Remember we're talking about huge magnifications and long exposures here, it's extremely easy to blur the pictures. Astrophotography is a challenging enough hobby to begin with. Inferior equipment can make it damn near impossible.
You'll notice I haven't even talked about the actual telescope yet. That's how important the mount and tripod is to astrophotography. So now that I've completely blown your budget, I'll try and be a bit more gentle on the telescope side of things. Probably the most bang for your buck in this case will be a newtonian reflector telescope. They're by far the cheapest type of scope per inch of aperture. Sort of big and unwieldy, and they require very precise and regular maintenance (called collimation). I'd recommend a bare minimum of 5" aperture, but as high as 8" if you can manage it.
Then you have to figure out how to mount your camera to the telescope, which is a black art in and of itself. Duct tape is not recommended. For most SLRs and telescope brands you can find a suitable T-mount adaptor which will allow you to attach your camera in place of the telescope's eyepiece. For non-SLRs, I'm not sure. If you were thinking of getting an actual astronomy CCD camera (such as the popular SBIG brand) well that alone will blow your budget and then a whole lot more. Then you'll want a second one to use it as an autoguider.

Do I shoot incredibly dim deep sky objects? nope I only have a old SLR digital and a 10" dob, not enough light collecting capability for the distant stuff. But i got photos of the horsehead and other nebulas that upset the guys at the club that have

Here's what my own experiences have taught me: Get a Dobsonian. With $1000 you can get a 10"-12" Dobsonian and still have tons of room for accessories. A dobsonian is very portable compared to a refractor and with near zero setup and takedown using it is much easier than a refractor too. 10" is a lot of aperture and you won't catch the "aperture fever" for something bigger for a while. The scope I eventually got is an Orion [telescope.com] XT10 Intelliscope [telescope.com], but you may not want the computerization with your budget.
I found the people at Cloudy Nights [cloudynights.com] very, very helpful. They have reviews of lots of products as well as their forums and they tend to specialize in getting the most out of your money.
As far as books go, I use Nightwatch [amazon.com] by Terence Dickinson every night I observe just for the charts. Star Watch [amazon.com] by Philip Harrington goes well with Nightwatch as good place to find new objects for the beginner. A lot of people suggest Turn Left at Orion [amazon.com], but I fount it to be a bit slow and the charts lacking in lower magnitude stars for their size.

If you're serious about the stargazing, forget the pricey glass. Get a decent set of binoculars and a few good books, and one of those plastic "Star Wheel" sky charts.
For the binocs, a basic pair of 10x70's will set you back a hundred and fifty bucks or so online. For the books, try Astronomy for Dummies and Left Turn at Orion. Also, your library will have back issues of Sky and Telescope - read 'em, and then visit their site. [skyandtelescope.com] They have star maps you can print out that shows what's worth looking at each month. Try not to be too put out by their over-agressive marketeering.
The learning curve will be steeper than a big-bucks robotic "Goto Scope" that aims and focuses for you, but with a nice lawn chair, some decent binoculars and a rough understanding of what you're pointing them at, a night under the stars won't fail to deliver a few thrills.
Once that gets old, then look into the big-money glass. Telescopes, on their own, are a pretty damn rewarding hobby, especially once you get into making and modding them yourself. But unless you really, really know what you're after, dropping a grand on glass isn't a good idea. It likely won't be anywhere near what you want once you understand what that is.

In looking back at my experiences, the first one was the only one that really gave me any pleasure, as I bought it for and observed Haley's comet. Everything else was disappointing.

Second, you need to ask yourself, do you want to do Science, or have fun, or something more like Art ? If you want to do science, you should look into
- asteroid occultations (these always need more data) or
- variable star observing (look into the AAVSO [aavso.org] or
