5/29/2003: Big space rectangle
SteveDallas Thursday May 29 02:57 PM Damn! That's wierd. My immediate reaction is that it's an artifact of the optics. Of course, I'm sure they've eliminated that thoroughly. xoxoxoBruce Thursday May 29 05:20 PM Great picture UT! SteveDallas Thursday May 29 05:35 PM No, see, this telescope was to be used for astronomy... I have surveillance cameras for the neighbors! Undertoad Thursday May 29 06:16 PM Quick question, do we need to live in an area with better darkness for good telescope usage? That Guy Thursday May 29 07:01 PM Quote:

Elspode Thursday May 29 09:26 PM Congrats on the new 'scope, SD...sorry about the condition of the first one, but Meade is a very reliable company and hopefully they'll have you a shiny new one asap. SteveDallas Friday May 30 12:30 AM Quote:
Anyway, UT, a good question. There is (naturally) a whole organization devoted to fighting light pollution (http://www.darksky.org). It's very bad around here, but how much it affects you depends on what you're trying to look at. The moon and planets are close enough and bright enough that viewing them really isn't affected by light pollution. (Though, ideally, when you have one eye at the telescope eyepiece, the other eye won't have a streetlight shining in it.) Fainter stars can get washed out, but then stars are only seen as "point" sources anyway. Where the light pollution really hurts is with larger, more diffuse deep sky objects--galaxies and nebulae. Oh and comets, too, tho of course they're solar system objects. I've seen the Andromeda Galaxy (that's this one that most people have probably seen pictures of, and no unfortunately it does not look like this in any telescope, it's the magic of film) through my telescope from my backyard, and it looks like a dim smudge with a less-dim smudge at the center. In a real dark-sky environment you can see it with no telescope at all! Good job Elspode, do you have a scope now? I have used a 10" dob and an 8" Celestron SCT (both borrowed), and I've discovered that I need something far smaller for my purposes, or I just don't drag it out and set it up as much--hence the ETX90, and since I'm mostly interested in planets the long focal length doesn't bother me. 'Course that doesn't mean I don't lust after the big SCTs and dobs. (The fact that they're practically giving away the ETX90 now doesn't hurt either! ) If anybody in the Philadelphia area is interested in looking through a telescope, the Delaware Valley Amateur Astronomers club hosts public viewings once a month except in the dead of winter. The next one is June 7. It's free of charge and you will typically get a chance to look through darn near any variety of telescope on the market. linknoid Friday May 30 12:49 AM Quote:
