Telescope Eyepieces?
My father-in-law just gave me his old Meade ETX-60AT telescope. The problem is, it's missing both eye pieces and user manual. I managed to download the user manual but the eye pieces are still eluding me. How would I go about getting replacements? Do the eye pieces HAVE to be the same brand? It came with a 25mm (1.25") and 9mm lenses, do I HAVE to get these or can I choose others? How will I know what I buy will fit in my telescope? I'm new at this and could sure use the help.

They don't have to be the same brand, but you might need to buy a bushing (adapter) to make another brand fit.
Go here http://www.telescope.com/ and see if you can find the info you need. I think the only thing that matters is the diameter of the eyepiece ("objective"), but you can check the learning center at their site or get the 800 number and call for some help.

Yes, a Barlow lens will double the magnification of any eyepiece so 10mm + 2x barlow will give the equivalent of a 5mm eyepiece. Since you already have a 20mm eyepiece you might prefer a 2.5x or 1.8x barlow, so that you aren't duplicating the 10mm with the 20mm. Just don't buy the very cheapest barlows though, they will degrade the performance of the eyepieces.
