No Eye Relief
By E. Tabor
I should have listened to the reviews here! There is no Eye Relief on this. It is almost impossible to get the whole field of view. This 4mm was worse than the extremely cheap 4mm that came with my FirstScope (I don't know how that is possible)! I only used this on terrestrial views and decided it was not a good purchase. I also bought the 9mm Omni which is much much better. Look for that review when skies clear so I can use it for non-terrestrial viewing.
I am returning this item. It sucks I have to eat 25% of the cost on this EP but I found it almost totally useless. I will report back on how the return goes with the seller (Adorama).
Update:
Adorama accepted the return and the refund was quick!

Does what it is supposed to do.
By AndroMike-eda
I use it for Saturn. Most astronomy objects will be too dim to see much with this eyepiece. Jupiter is also bright enough. The hole on a 4mm eyepiece is very small. Focal length/ eyepiece mm=mag. Gives about 185x 5"750mm f/6

It does what it's supposed to do.
By Arg0
It does what it is designed to do. It is a 4mm eyepiece of pretty good quality. I bought it for my 4.5" reflector telescope. My scope has a 1000mm focal length, so I was hoping for an awesome 250x magnification. Well I got the 250x magnification, but the image was not very awesome. Yea, I know, I exceeded the recommended magnification for my size scope, but I had to find out for myself. The image through my Celestron 10mm eyepiece that came with the scope is much better, and the Celestron 20mm eyepiece it came with better yet. This eyepiece may be better suited for a larger mirrored scope.
My main issue with this eyepiece is that it is uncomfortable to use. The eye relief is VERY short. I almost have to have my eyeball touching the lens to see the full field of view, and my eye so close that my eyelashes constantly press against the lens and get in the way. Not enjoyable.
