# Celestron Nexstar 102GT

Good day folks. My Grandson would like to start using this Telescope Celestron Nexstar GT102, has been in the basement for years, and unfortunately, we appear to have misplaced the eyepieces.

Just wondering if anyone had any insight what would be a reasonable eyepiece for me to buy so he can see the moon at the very least decently enough.

Also, would Amazon be a good start for eyepieces that way I can get them fairly cheap and quick.

• Was the eyepiece end of the telescope closed with a cover all of this time, or was it left open? If open, you might want to also ask a separate question about how to deal with dust, bugs, and anything else that may have gotten into it! – uhoh Sep 2 '20 at 4:08

The manual says the original eyepieces had 1¼ inch barrels and focal lengths of 25 mm, 20 mm, 12.5 mm, 8 mm (all reasonable) and 4 mm (not so much). If I had to pick two replacements for a beginner, I'd get a 25 mm and a 10 mm. You can probably get an entry-level Plössl by Meade, Celestron, or Orion for US \$20-25 from the Cloudy Nights classifieds or \$30-40 new.
