All metal construction and anodizing aluminium process, sturdy for long time use. High-quality aluminum material makes the product lighter and easier to carry.

Sleek silver lens barrel with safety undercut reduces the possibility of the eyepiece slipping out of the telescope or diagonal, increasing the stability of the connection.

The inner thread design can effectively prevent the reflection and achieve the maximum contrast, which is conducive to planetary observation.

The intimate rubber traction ring design can increase the friction, so that it is easy to grasp and not easy to slip off.

The weight n build quality is good. Its also has good brightness to it for being a medium powered eyepiece and not too big for its size.

It threads onto an M42 visual back or slides into a 2" mount (Barlow or 45 degree) with no problem. It provides a good clear image and has enough of an edge on the front eye cup to allow a smartphone / clamp to attach and capture a picture. When viewing planets, it effectively double their size (with an 11" SCT) in the viewfinder. The biggest drawback is the front of the eyepiece does not have a threaded ring or enough of a lip to attach either a DSLR or CCD camera using a compression ring, requiring additional modifications (which may void the warranty) if your intent is to use it for deep sky astrophotography.

field of view not quite 80 degree's,performance just ok not oustanding but definitely worth the economy price paid, in all fairness used this eyepiece with my 102mm refractor with light pollution and not the clearest of nights.

This is actually 2 eyepieces in one. The eyepiece has a small Barlow in the front making the 30mm a 20mm. The view is clear and the eye relief is excellent.I have an 8se so I didn’t want to spend thousands on eyepieces.I highly recommend this one

Though I own a number of eyepieces I’ve been upgrading to the wider field of view. Worth the extra money.

Its OK for the price. Lots of glare. Does NOT work well with a cell phone camera on your telescope, too much glare. Honestly its an ok budget eyepiece. You can see Orion Nebula, Jupiter, Saturn, all the basic stuff but not in the greatest detail amd you will have to contend with glare.
