I am a beginner looking for a good telescope. I am currently looking at a Celestron Skywatcher telescope. There are three lenses which comes with it: super wide 10mm. lens as well as a wide angle 25 mm....


Magnification is the LEAST important property of a telescope. Quality optics and aperture are much more important.

The best bang for the buck is a reflector style telescope ion a Dobsionian mount. You get the most aperture for the least amount of money. Like this one--

The scope above has 6 inches of aperture and is mounted on a very stable alt az mount called a Dobsonian mount.

I am looking for a telescope and I saw the JASON MERCURY 420 telescope on craigs list. I have never owned a telescope, I am a ameture photographer and I watch every science show on tv. I am not a 8 year...


Do NOT buy that telescope.

Second, to take long exposure (several minute) astro-photos you must use a GEM mount like one of these:

http://www.telescope.com/control/accessories/mounts-and-tripods/orion-atlas-eq-g-computerized-goto-telescope-mount

Then you need to decide on the scope to use. Something like this would work:

http://www.telescope.com/control/product/~product_id=07338

or this:

http://www.astronomics.com/main/product.asp/catalog_name/astronomics/category_name/U5QNWB3RKWWL8N3EL99F9DX9A0/product_id/AT6RC

Additionally you will need some accessories to mount the camera onto the back of the telescope, and you will need to learn how to polar align the mount so it will accurately track the sky.

What can you tell me about the Bushnell 420 x 60 Refractor Telescope?


No matter what the box says, 110x is the maximum power for a 60mm objective lens. The tripod is weak so stability is a problem. Fair for lunar observation and fair to poor for planetary viewing.
Go spend some money on a decent telescope A Celestron 114mm reflector is only about $150

Our Tasco telescope has a broken lens. Is it


Not worth fixing these small telescopes. There are hundreds for sale on craigslist.com.

DO NOT BUY another toy "department store" telescope. Read my TIPs on my profile page. and look at this web site for a Dobsonian telescope.

You should be able to order one from Tasco I would imagine. Try contacting them about the part through this website: http://www.tasco.com/section.cfm?s=Telescopes
Other sites say that parts are available through Tasco, so you should be able to procure one. Good luck!

You can buy eyepieces at many on-line retailers. Measure the hole. Eyepieces come in 3 sizes; .965, 1.25, and 2 inch sizes.

Missing lens's


Eyepieces are typically expensive. Here is a link to some lower cost ones at $24 each. You only need 1 or two to get started. try 25mm and 12mm.

Lost lens to bushnell 18-1561


I have a similar problem with my Bushnell 18-1650!

As you can see below, the plastic thing that holds the lens snapped off from the telescope's diagonal, and is now lost along with the eyepieces. This is a childhood scope I'm trying to rescue!

Should I:
1) glue a new eyepiece straight onto the diagonal
2) buy a new diagonal AND eyepiece
Or do I need to just buy a new telescope?

Thanks in advance.
