Identifying Eyepiece Abberations

[John]

For those who are interested I thought I'd post a link to this piece that has been posted on the Cloudynights forum by Don Pensack:

It's pretty comprehensive I reckon and provides useful information for those of us who like comparing eyepiece performance

I found the part on cooling really large eyepieces interesting as I'd not considered that before.

Thank you John,I just skimmed this post & I realized that for now my eyepiece judgment lacks knowledge.This will help me give more objective observations of my eyepieces...The TV 16mm T5 is here today, just have to bip across border to pick it up.I appreciate the eyepiece reviews given by yourself and other experienced observers & after I read that post & get some more time at the eyepieces,I'll try to contribute back to this site,as SGL has helped me immensely.
