Orion "edge-on" 19mm

[The Mekon]

Wanted Orion 19mm edge-on eyepiece. Now discontinued according to Bintel. Willing to consider other options, what I want is an physically small eyepiece around 20mm with a wide field. The orion is only 2.4" long and weighs just 4oz.

Same 19mm eyepiece also sold under Astro-Tech name

thanks John
