Hi, we have a Celestrong StarSense Explorer DX6 Schmidt-Cassegrain as our starter telescope. It is supplied with two eyepieces: a 40mm and a 10mm. So far we've been successful with the 40mm in getting that to focus and general usage of the telescope - the "easy" targets: Jupiter, Pleiades, Orion Nebulae etc - we can view with good clarity and the stars are proper pinpoints. The 10mm however defies all of our attempts to get it focussed - when turning the focus knob on the scope we can at best get a fuzzy shape rather than anything well defined - any ideas or is the eyepiece "broken" in some sense?
One piece of advice was to collimate the telescope - as far as I have read and seen this is fine and I guess the problem lies elsewhere and I'm at a total loss to figure out what to do or try
THanks in advance,
