There will be nothing wrong with the Plossl apart from the aforementioned slight tunnel vision all 40mm inch and a quarter eye pieces suffer , you will get great views of star cluster,s etc in your scope. Enjoy the views and don't worry , my first low power eyepiece was much worse , trust me.

Their current 40 mm Plossl looks differently to the AG 40 mm Plossl.
I've attempted to find out what is going on, and found the article http://www.cloudynights.com/page/art...onfusion-r2103
It appears that the Meade ("enhanced" 5-element) Plossls were made in Japan until 1998. After that, Meade moved the manufacturing to Taiwan, and downgraded the eyepieces to the "real" 4-element Plossls. In 2002-04, Meade moved manufacturing of this series of Plossls from Taiwan to China. The Plossls were downgraded even further. The article author did the testing and comparison of those Plossls... it appears that the performance decreased with each move.
So... I wonder if the AG has the "old", Taiwan-made Plossls in stock. Anyway, I must confess of my foolishness -- I have placed an order for the AG 40 mm Plossl for $25. Now I am thinking that this is a waste of money. |
