I still have a Celestron G8N from quite a few years back. I think it's been out of the garage maybe three times in the last five years.  :'(

It's fun to get out if you ever get a "warmer" winter night. That's when the air is clearest and the sights are best.

I need to do a little more "through the lens" photos with my digital camera. First attempts were promising, but a better mounting system was needed. I guess I just got too busy doing other stuff and forgot to go back to it.

I'm gonna purchase a Celestron C-14 Scmidt-cassegrain and do some imaging with my Canon 5D and a webcam.

This scope is a monster but ought to do deep space objects pretty well.

That's one heck of a nice scope. The largest S-C I've seen myself was a 10" and it seemed huge. A 14" is a monster (no porn jokes here, please). I would think you'd need a nice semi-permanent place to house it though. Too big to be hauling to and from a viewing site.

Hey

I'm on the verge of geting a Meade 8" SC.  I am interested in viewing and photos but I am a newbie to say the least.  I have never looked through a telescope in my life.  Does that qualify as a newbie?

After reading all the propaganda on all the web sites, I want to ask those with more experience.

Just how much can you see through an 8" telescope?  Can you see other galaxies, planets in the solar system?  Is it spectacular or just little dots of light made bigger.  My first guess is that  you can't and can only get other galaxies on film with a time exposure.

Also, can someone tell me if a Meade ETX will track objects accurately enough to get a sharp photo?

Thanks for all your help.

I had a celestron 8" SC for a while and you can definitely see larger galaxies like Andromeda and M51 (Whirlpool galaxie). Plenty clusters and nebula's. Zero detail on mercury and venus. On the close approach of mars 10 years ago or so I was able to see the polar ice cap. That was the only time I could see surface detail on mars with the 8". You can definitely see bands on Jupiter. On a VERY clear night I was just able to make out the Cassini gap in the rings of Saturn.

As for photography I have never been very successful. My Celestron had a single arm mount and didn't track very well even with the most meticulous alignment. If you want to try to hand at photography a quality equatorial mount is the only way to go.

Thanks Rhino

I looked at EQ mounts but they are more than I wanted to gamble on my first telescope.  So for Venus & Mercury are they too bright or too far away to get detail?

Meade has one now that aligns itself & talks at you.  It is about $300 more than one that just tracks or I guess moves to something in the database after it is aligned.  That is what I'm considering.

With 30,000 objects, it should keep me occupied for a while.  The one that talks has 100,000 objects.

:yikes: Tap the breaks a second, jim-d. Especially since you've never even looked through one.

Before you drop a couple of grand on a telescope (and several hundred more on eyepieces, Telrad, books, charts, and many other extras!), PLEASE take some constructive advice from someone that has been there, done that.

I'm not sure where you live, but I'd stongly suggest that you find a local astronomy club and attend a few meetings. If you can't find one through Google, call your local science museum and I bet they have a contact for you. Most clubs normally have a viewing site that is out of town and dark(er) and almost always have at least one weekend a month where they'll let visitors come out and look through their scopes. Most of the people in these organizations are more than happy to share their scope with you, especially if you're a newbie. (Plus their experience will be very helpful when first learning to find things.) Many of these clubs also own scopes that are free for the members to use, and the minimal cost to join the club is a much better way to spend your money for the first year or so. You get to try out all kinds and see what you want, or you may decide that using the club's scopes satisfies your curiosity enough to save you a lot of money.

As far as "what can I see?", you'll find that you can see very little if you live in or near a major metropolitan area. The typical neighborhood backyard is bright enough that you are almost guaranteed NOT to see much of the more interesting objects. And under NO circumstance will you see anything like those Hubble photos that are in books and on the net.

I also suggest that you spend $100-150 bucks on a good set of 10x50, fully-multicoated binoculars and a book or two. Two books that I'd suggest are "Turn Left at Orion" and "The Backyard Astonomer's Guide". The first is great for helping you find the "easier to find" objects right from your backyard. Even if you later decide that a scope is the way to go, those binoculars will come in VERY handy when you're in the field. Since everything is "right side up", it's easier to find things than it is through a telescope, too.

Just my two cents worth.

That's probably very good advice.  This was supposed to be a joint b-day present for us but I like the idea of checking things out before I spend $1,400.

It will be used in the Pocono Mountians in PA where the sky by itself is pretty nice.  Could be better but very nice, especially the winter sky.  The air is clearer and you can actually see the Milky Way.

In Philadelphia you see maybe 4 stars on a good night.

Thanks

Wally made some excellent points. I should have put my response in perspective. I live at 7500' in a dry climate in Colorado. My house is between Denver and Colorado Springs and has its share of light pollution. But most clear nights here I can easily see the milky way. I am also just a few hours from OUTSTANDING dark skies when the weather is good. When I saw the polar ice cap on Mars I was home. But when I saw the cassini gap with the 8' I was in the mountains at 9500' with zero light pollution.

When I go down to my wife's parents place in NM about 100 miles from Albuquerque and 30 miles from the nearest town at 8000' the skies are AMAZING. And there an 8" with a good eye piece works well but my 16" dob with 17mm Nagler just blows me away.  You can count the stars in a cluster like M3.

Check this out guys, it's free and incredibly powerful.

http://www.stellarium.org/

Stellarium is a free open source planetarium for your computer. It shows a realistic sky in 3D, just like what you see with the naked eye, binoculars or a telescope.
It is being used in planetarium projectors. Just set your coordinates and go.

If this is your first purchase, it would be best to stay with  visual observing only, that way you get the computerized "go-to" option and can get satisfaction right out of the box.
Astrophotography is quite a few steps up in equipment and degree of difficulty EXCEPT for web-cam planetary imaging which is quite easy and gives some of the best planetary images around!

If you want to see good stuff, aperture or size really does matter!
One of the best deals out there IMHO is this scope   http://www.celestron.com/c3/product.php?ProdID=78
used. I've seen them for about $1800. on the market and with the large 11" aperture and the computerized go-to capabilities, you'll get the most bang for the buck by far! It is still portable and would provide tracking accuracy good enough for 1 minute exposures (which is enough to blow your mind).

Try the Cloudynights forum and also Astromart as well a Craigslist.  Check this:  http://www.cloudynights.com/classifieds/showproduct.php?product=51482&sort=&cat=11&page=1      that's a lot of scope for $1400.
