I don't know why,but for some reason,in my 70th year,I am getting the astronomy bug.I've been looking at various telescopes on ebay and Amazon and am totally confused about what I need.Yeah,hard to believe I could be confused.Anybody know about various telescopes and have a recommendation?So far I'm looking at a reflector type like the Celestron 127.The price is reasonable at around $200,but I don't know if that's what I need.Many thanks in advance for any help.
 
I started out with a mak-cass 127mm (5") on an equatorial mount, then got an 8" Orion Dobsonian which I really liked as far as set up.  It's just bulky and big to store anywhere.  The 5" with the mount is easier to store and carry but a b*#$% to set up and align.  A royal PITA for me. 

So I started working with 70mm binoculars and I'm sold.  It's easy to carry.  I can use any tripod (but be sure to get a really solid one or it will be frustrating with shake) and I can upgrade to a parallelogram mount when I get the money.  

The Astronomical League has a Binocular Messier Observing program, along with a couple other Bino observing programs, that help with giving goals and things to look for.  Otherwise, you may end up just messing about and missing some really spectacular stuff.  Messier Binocular Observing Program  Also consider looking for Astronomy clubs wherever you happen to be.  They are super helpful to newbies and visitors and members.  

My home club has a lending program too, where people can try before they plop down the mega bucks and avoid the mistakes of getting something that they won't use.  The general mantra is that the best telescope is the one you actually USE.  Astronomy Clubs
 
My thanks to the both of you.Sounds like good advice and I'm going to take it.What size do you recommend?10x50?Maybe larger?
 
One thing to consider with binos for astronomy is exit pupil size. The older we get generally we lose some of the ability to take advantage of larger exit pupil sizes. For a 25x150 binocular, that would be an exit pupil size of 6. For a 15x70 that would be 4.66 and 20x80 would be 4. I got the 15x70 ones because they were a good compromise between exit pupil size and price. The 20x80s were a good bit more expensive and heavier. I think it was $70 vs $110. If you want to spend the extra $40,the 20x80s would be good. Just know that these are NOT ones you can pick up and take hiking. You pretty much HAVE to use a tripod with them. Don't be fooled by thinking that if 20x80 is good, then 100x80 is even better. The 20 refers to the magnification and the 80 is the objective size, or the amount of light gathering capability. At higher magnifications the image you see is dimmer in the same objective size. Now that 100x80 would probably be awesome in the daytime looking at an eagle in the distance. But at night, no way.

So if you want to go with binoculars, think about what you might want to use them for. Just astronomy? Or double duty? If you want something that you can also take hiking, then 10x50s are a good compromise in that respect and you can see a surprising amount of night sky objects in those. Really!

I think what a lot of people don't realize is that you can't expect to see in any telescope or bino what you see in photos. You can only expect to see in black and white. Think dim fuzzies. Now to me that is still pretty awesome. It's like a treasure hunt to me. I know where the treasure should be able to be found (or I have a map), but can I find it? That's the challenge and the fun. I've become fairly adept at seeing the anomaly in the sky. Goes back to kindergarten and the which is of these things is not like the other type of fun.
 
My first scope was an 8" Orion Dobsonian, and I loved it for its ease of use, but as mentioned by StarEcho, it was a real beast to store!  The thing was huge.
Still, it was a great design.  Personally I prefer wide-angle, large aperture, light gathering scopes over high power, smaller aperture models.  It's much easier to find what you're looking for when magnification isn't the goal, and you can always get a Barlow lens if you need to zoom in a bit.  

Another advantage of the light gathering design is that you can view objects that are further away or very faint.  Magnification will only get you so far, unless you're doing your viewing from the desert with zero light pollution, then magnification is great!   

Later I replaced it with a smaller reflector on a standard tripod, but I was greatly disappointed with the results.  

In the end I sold both scopes and gave up the hobby because even with a telescope, distant objects and planets tend to look only like slightly larger white spots in the sky than they do without a scope at all.  :p

Bob, there's a whole subfield of astronomy that uses powerful binoculars instead of telescopes.  See:
A google search on binocular astronomy will turn up numerous web sites devoted to as well.

+10 On binoculars for astronomy--also dual purpose for bird watching, etc.

Short video on choosing binoculars (for astronomy):

 
Thanks so much for the info.Some great folks here.I ordered a pair of Celestron 10x50 binocs.I'll start there and give it a few weeks and see where it takes me.
 
NASA says its old and obsolete; so you can have it, free.

But you gotta pick it up . . .
 
I've had a pair of 7 X 50's some time as I live here alongside of the Ohio River.  They amplify light and I can see things after dark that I can't see with the naked eye. 

Awhile back I found a copy of "Stargazing with Binoculars"  (firefly series)  third down on Optimistic Paranoid's
Amazon List.  (I picked my copy up at Ollies, "Good Stuff Cheap" for $4.99) 

I'm more interested in first magnitude stars and constellations. (mythology, history, lore etc of these celestial bodies) 

Binocular Astronomy appeals to me when Van based as the optic can serve a dual function and take up little space.   Plus, in their case they are quite durable for traveling. 

For some time I've been interested in Edmund Scientific 'Astroscan telescope".  No one I know has one and I wouldn't purchase one until I've been around one to check it out.  It appears to be durable and realistic in price. I like the ball and socket mounting system it uses too.

But I find ancient astronomical devices fascinating too.

The Antikythera Mechanism

Discovered in the early 1900’s, the Antikythera Mechanism is an ancient analog “computer” used to predict the movement of the moon and stars that dates back to somewhere between 100 and 205 BCE.

Who was believed to have made this and other mechanism's like it ?

Edmund scientific is now called scientific online and no longer sells the astroscan telescope. I was just looking for it myself, it would make a great telescope for van dwelling. You can get them on eBay.

That was a good choice, you will use the binoculars more than the telescope you had chosen! When looking at telescopes to buy small and simple is almost always best. They get used more often because they are easy to setup and are not heavy. The bigger telescopes can weight in at 50lbs and up.

Small refractor (80mm to 102mm) with a short focal length of about 600mm will give you nice views of the sky at low power.

[font=foundation_sans_cdregular, 'Helvetica Neue', Helvetica, Arial, sans-serif]90mm Maksutov-Cassegrain is small but has a long focal length and will be good for looking at the moon and the planets. And still compact and light, easy to travel with. Like the [/font]Celestron nexstar 90 SLT
 
What to look at?
I have a ebay plastic chinese 15 dollar telescope and i can look at the Southern Cross and spot NGC4755, a cluster called the Jewel Box. http://apod.nasa.gov/apod/ap100817.html
I would like a celeston 70mm scope, but i am currently reducing the number of things i own...
