I have a Celestron firstcope 70 with mount that I intend to give to my 11 year old nephew. It does not have any eyepieces or a diagonal. If you have some good but cheap eyepieces laying around please let me know. Cosmetics are not important. I would like these to be as inexpensive as posssible. I think something in the order of a 25mm, 15mm, 10mm and a 6mm or close to these would be nice.
Thanks for the help.
