Review on Pomya Telescope Eyepiece Datyson Observation by Donnie King

I saw some negative reviews about it but I ordered one. It arrived today and I was surprised by its quality. This is not fake. This is a well made Chinese import. Telescopic zoom lenses need to be refocused each time you adjust the magnification. Unlike zoom binoculars, they lose focus when the magnification changes. This is completely normal with telescope zoom eyepieces. If you have a high power eyepiece of 10mm or less and a low power eyepiece of 25mm or more, you will notice the same thing. If you change eyepieces, you will need to refocus the telescope. I buy/sell/trade/repair and upgrade telescopes here in the Denver area. I will be using this on one of the telescopes I am selling. Today I ordered 8 more of these eyepieces to use in my telescope hobby shop. That's a great thing!
