4 of 5 APM 30mm UFF Works Well for me May 3, 2022
Reviewer: JimK from Albuquerque, NM United States  
I am very pleased after using this EP for ~6 mo now (for my max rating it must be fully Dioptrx compatible).

My 14.5" f/4 reflector, w/Paracorr II, now has this EP as its home, with a nice ~6.5mm exit pupil & almost 1.3 deg FOV. I avoid eyeglasses for astigmatism, using a Dioptrx (it fits securely in the rubber eyecup after removing the Dioptrx lower housing).

I like its light weight, minimalist form, & excellent views.  It is great for starhops to Hickson galaxies & Abell/ACO galaxies, & has been used for seeing larger OCs & asterisms, very faint large galaxies, nebulosities (Sh 2-234, 2-273, 2-301, etc.), & dk nebulae (Horsehead, etc).  With & w/o O-III filter, the Veil was great, & I saw (large) dwarf galaxies: Scl, And I/II/III, Peg, Psc.

It's not the lightest 30mm, nor widest AFOV, nor max TFOV for a 2" EP, but it is an excellent lo pwr (~56x) EP for me & I use it more and more.  Many have spoken of its virtues, & I confirm them though my usage.

Reviewer: daniel wood from Keene, TX United States  
Ordered this eyepiece at 6am and had shipping confirmation by 6pm same day. Spoke online about types and eyepieces good for my particular set up and found this eyepiece. Which in my amateurs eye is fantastic. It's the first nice eyepiece I have purchased and have no regret.

5 of 5 Good performance and good value November 11, 2021
Reviewer: Peter from Madison, WI United States  
This eyepiece work well in my F711/102mm f7 refractor.    Gives a 3 degree field of view that is sharp edge to edge.    Good for viewing extended objects and for finding.

Comfortable viewing that is not too demanding on eye position.      It is an easy eyepiece to use.

Not too heavy for a 2 inch eyepiece.   No undercut on the barrel.

Plenty of eye relief for glasses with the eye cup folded down.   I use glasses at low power due to astigmatism.

Single vision eyeglass lens give the best experience with this eyepiece for me.   I can soak in the whole field with moving my eye position.   Progressive bifocals work, I just have the feeling of needing to move my head and look where I want the view to be sharp.  

My wife has zero astigmatism and doesn't observe with glasses.     She  likes the views as well.    She agrees that it is a comfortable eyepiece.
