<p>As you’ve discovered, decent telescopes are very expensive.</p>
<p>I have a 6" Celestron reflector I bought years ago at a pawn shop for $50-100 although I’ve purchased a couple of additional eyepieces for it (which magnify the light collected by the scope). It’s fine for seeing quite a bit of stuff including the rings of Saturn, 4 moons of Jupiter, etc. We often have excellent viewing conditions where I live but truthfully, I rarely use it. I recently considered getting another telescope, probably a several thousand $$ Meade or Celestron with a powered tracking mount but after thinking about it more, I decided I wouldn’t use it enough to justify the cost. </p>
<p>It’s all in the usage. I had a colleague who was very into it and had tens of thousands of dollars worth of scopes, bought a pickup truck to be able to carry them (one was very large), and made frequent trips to the desert east of here, where the viewing is outstanding, and sometimes to the top of nearby Palomar mountain, home of the 200" Hale telescope (formerly the world’s largest). He and his W used them enough to justify the cost in their minds (plus they had no kids to consume their dollars for college).</p>
<p>I wouldn’t go overboard for the first scope since you have no idea how much she’d use it, astrophysics major or not. How much she’d be able to use it is influenced by the sky conditions where you live as some other posters said. A used scope is, IMO, just as good as a new one as long as it hasn’t been abused and knocked out of alignment. There are likely others who’ve spent the money, realized they don’t really use it like they thought they would, and are selling them. Yet others who are really into it may be trading up and have some scopes for sale. Telescope retail stores may also have some used ones for sale. </p>
<p>If there’s a telescope retail store in your area (not a big box that happens to sell one or two models of scopes), you should probably pay them a visit, explain your usage and budget, and see what they recommend. </p>
<p>Some people start with a good set of binoculars rather than a telescope - something to consider.</p>
<p>With telescopes, the sky’s the limit. (so to speak
)</p>
<p>Edit - I just read that Meade moved its manufacturing out of the USA to Mexico. Apparently Celestron still manufactures in the USA. If you care about such things, you might want to consider Celestron over Meade because of that.</p>
