The all-metal structure and anodized aluminum process are not easy to scratch and are durable. |
Nice large thumbscrew that is easy to turn even in very cold conditions or with gloves on. |
It has filter threads at the bottom for 1.25" telescope filters. This eliminates marks on your eyepiece barrel. |
