An Amazing Visual Eyepiece! Great glass! And Comfortable to use!

This is currently my favorite 'Go To" eyepiece. The view is incredibly wide and precise. The glass is outstanding but as a result it is a "heavy" eyepiece. I'm using on a 10 inch Orion goto Dobsonian in combinations with a Teleview Paracor so the front end is a little heavy but I compensated with a magnetic weight from Orion. The views are amazing....The Beehive Cluster, The Double Cluster, Christmas Tree Cluster, M13 Hercules Cluster, M11 Wild Duck Cluster are incredible to look at with this eyepiece. I liked it so much I just about bought all the Luminos eyepieces as a result. Compared to the Plossel eyepieces I had this is like comparing an old style tube television picture to 4K. The retractable eyecup is an added bonus and very comfortable to use when you want just a little bit more shielding from light pollution. For the Price there is no comparison in the new eyepiece market. Huge bang for the buck! High recommendations. Get yourself one and you'll see!
