Tip & How-To about Optics

Where can I buy a USED telescope?

Once you get involved with the amateur Astronomy hobby, you will probably have more than ONE telescope. It's just like the fishing hobby where you eventually have SIX rods and SEVEN reels, along with three tackle boxes!

Here are a few places to look for good used telescopes.

This is the TOP DOG of used telescopes and other astronomy equipment. www.astromart.com

Most astronomers take very good care of their equipment. The neat thing about this web site is that the buyers rate the sellers and the sellers rate the buyers. Their rating is visible right next to their name. In any case ask for pictures of the equipment if none are posted, and call the seller to verify before sending your money. PayPal is accepted by most sellers. It will cost you $12 to join and see the full ads on the site. You will save more than $12 when you buy something!

Used-Demo- Equipment at the large Dealers
Most of the larger internet dealers maintain a list of used or open box equipment. These usually carry the NEW equipment warranty, but ask before you buy. This is a higher cost solution but most dealers will accept a RETURN if the scope is not as advertised or dead on arrival.

I purchased my Meade LX90 used from a dealer in South Carolina. I called him and worked out a deal with a 90 day guarantee on a used LX90 he had taken on consignment. The scope has been trouble free for over 3 years now; and arrived in perfect condition.



http://www.astronomy-mall.com/ several used sellers on this web site.

http://www.khanscope.com/ see the used link at the top of the page and-or call them

http://astronomy-mall.com/astro.parts.outlet/ this guy has dozens of used scopes along with thousands of "parts".

Call around to the larger internet retailers and see what they have used in stock that might be of interest to you.

Your local Astronomy Club-
Another good place to find used equipment is your local Astronomy club. The members are always looking to upgrade and to help fund the upgrade by selling their usually GREAT scope equipment.

This web site lists Astronomy Clubs by State:

Contact the President of your local club and tell him what you are looking to buy. Most club's have a private member's only internet forum where equipment is listed for sale.


Yes, from time to time a nice telescope will show up on this web site! BUT! you must know what you are buying. Most of the scopes on Craigslist.com are junk telescopes that you do not want to own. You must be careful with your purchase as "scams" are known to exist on this web site. Buyer BEWARE!

I bought a very nice Celestron C6-SGT scope and mount on craigslist.com, but I called the owner and checked out the scope before handing over my money.

Hope this helps you find that FIRST or SECOND telescope at the lowest price possible.

Clear Skies!

Scope falls of tripod every time it is moved? Is this poor desin. Nothing seems to be broken

What type of telescope is it? Sadly there are a lot of poorly made "hobby killers" out there that suffer from poor optics and/or poor shaky mounts .

But knowing what type, model# & manufacturer would help narrow the problem down

You might also look to see if there is an Amateur Astronomy group in the area. They would likely be able to help.

need owners manual for Venture RX-7 telescope

You will not find a manual. BUT you do not need one.

This is a very simple reflector telescope on an Equatorial mount. The mount must be polar aligned in order to properly use the scope. Read my TIP in my profile section about aligning an Equatorial mount.

The major steps are:

Align the small finder scope with the main telescope tube on a distant object.

Set the Declination axis to your Latitude.

Align the main tube with the axis of the mount.

Point the entire mount toward the North Star Polaris.

Use the fine RA & DEC knobs to center Polaris in the eyepiece.

See this web site and my tips--

This is why we NEVER recommend an EQ mount to a beginner. Polar Alignment just introduces one more FRUSTRATION to someone new to the Astronomy hobby.

The eyepieces simply go into the focuser. The Larger the number written on the eyepiece the LESS the magnification.

Take the scope outside during the daytime and practice focusing on a distant object using the eyepiece with the largest number.

The manual WILL NOT tell you how to find those small dim objects in the sky. It's just assembly instructions.It does not tell you how to become an amateur astronomer.

Locate a local Astronomy club and seek advice from the members, who will be glad to help you with your telescope.
