This was exactly what I was looking for; thank you. I really wanted to know the differences in the anatomy of the different eyepieces. I would like to know the book or poster you were using in this video.
One of the doublet lenses fell apart on the right eyepiece of my Kellner style system. I found the internal lens bouncing around inside the housing. How do I cement/glue them back together?
Panoptic doesn't rival nagler, it complements it, both invented by Al Nagler. Also, naglers and panoptics have never been $100 except when the 4.8mm type 1 nagler was cleared out in 2004 for $105. Typically.naglers go for $300ish to $700. But some nagler clones are in the $100 range, or used to be before explore scientific doubled the price of their 82deg eyepieces after cutting off meade and celestron from selling their same versions of the eyepieces made by JOC who owns Explore scientific. But some are still $99 like the excellent UWAN type now sold by several brands in 4mm 7mm 16mm and the excellent alternative to the 26 and 31mm naglers, the 28mm UWAN, which ranges from $200 for the stellarvue, to $300ish for the meade PWA. All are made by the same manufacturer who made the original william optics UWAN 20 years ago.
