Great pinpoint images, M-27 looked awesome through it as did everything else we looked at through this huge eye piece. Jupiter really needed a N.D. filter for best views as it is so bright through this ocular. To really enjoy this at its best your going to need an assortment of 2" filters. This is a very good buy for a ocular of this type and quality and I plan on getting a couple more. (Posted on 10/23/2022)

I was a bit skeptical on the purchase of this eyepiece, but my first night out and wow! I have had an ES 14mm 100 degree in the past which also blew me away, and this is identical in terms of image quality and also affords the ability to use as a 1.25 inch eyepiece to use with a good barlow. I have used it with a GSO apochramatic 2.5x barlow (actually 2.15x is what others are telling me) with excellent results. Eye relief is good, and you will need to remove your eyeglasses to get the full immersive effect, but well worth it. You can still view much of the FOV with glasses on. I use this in a 14 inch f/4.64 dobsonian with no Paracorr, and only see coma on the outer 10+/- percent of the FOV, but I need that additional FOV to help me navigate my manual dobsonian. Build quality is very good, maybe not on par with the Ethos, but the image quality is just about on par with the Ethos. Highly recommend this eyepiece for any telescope. (Posted on 8/28/2022)
