Jarvis,

I have noticed the eye relief when using the barlow and the 15mm.

I also noticed that when I used the barlow and the older eps that came with the scope they seemed to perform better. The stars were brighter against the background sky. Is this my imagination or could it be that because the barlow is a better quality instrument than the older eps it has somehow helped or upgraded their performance? Note that I was shipped a Celestron shorty barlow because Hands on Optics was out of stock on the house brand. What do you think?

Thanks for the help,

Lenny M
