Hi everyone,
I had purchased a Meade 4000 14mm UWA (newer style with eyecup) here on Astromart and had a chance to use it last night. Let me start off by saying it has MAJOR problems. This is where I need your help....
The eyepiece arrived to me packed very well so I can rule out any shipping damage. At first glance of the eyepiece it looked as if the top part of the barrel (eyecup) wasn't screwed down all the way. The threads were exposed with about a 4mm space between the rubber ring and the barrel itself. Nothing was rattling around and the barrel was not loose.
When I put it in the scope (Obsession 15" f/4.5), MAJOR astigmatism. The outer 40% was BAD. Stars were short lines. It was kidney beaning too. I have used a different 14mm UWA in my scope before and it was REALLY impressive which neither problem was evident in those eyepieces. I immediately knew there was something wrong with it.
None of the elements are broken or scratched. Could they be in the wrong configuration? Does Meade repair old eyepieces? Is there a schematic of the element design out there?
Please help……Any information or suggestions would be greatly appreciated.
Thanks,
Jay
