Quoting B741 (Thread starter): appreciate the responses. Maybe I will just save up for a trip to the Lowell observatory!
Quoting B741 (Thread starter): am thinking of buying a new telescope. What would be the best one to buy-say around 100 dollars? I just want to make out the rings of Saturn.
With $100.00 to spend you won't see much to be honest.
If you are a beginner? I would recommend a Dof telescope. A quality 6" F-8 is a great start.
Also www.astromart is a great place. Join it and check out the forums, alot of great people there and they can help you.
I had a Meade 10" S/C Celestron 8" S/C and a Russian Tal 1 4" Newt. The 4" was hard pressed to see the rings of Saturn.
Also keep in mind most local stores will have boxes promising you 450power with a 3" scope, you will never get that.
As a rule of thumb you get about 50 power per inch of lens or mirror.
A 6" Newt at F-8 will give you about 300 see-ble power. The smaller the Eye peice the darker the object also.
As a rule of thumb to figure out the power of an eye peice take the focal lenght of the telescope and divide it by the eye peice power.
So a 1200mm focal lenght with say a 25mm ep will give you about 48 power with a 2x barlow you will get 96x
Also keep in mind that Saturn is twice away as Jupiter....You will see at least four of Jupiters moons and several of Saturns but they will look like bright stars.
As mentioned a refractor would be best and yes you can get a few good ones under $1,000.00 like a Televue but you will not get power out of them, they are great for wife field though and taking pics with their fast focal lenghts.
