ZWO 30mm f/4 迷你導星鏡 - 30F4

The included dovetail bar made mounting this guide scope on my rig a breeze—no separate adapters needed. Picked up a faint guide star in under 30 seconds during testing, which impressed me.

Set it up in five minutes and the rings held my camera's guide scope rock solid all night. At f/4, it pulls in plenty of stars for guiding even on a hazy suburban sky, and the whole thing weighs barely nothing on my mount.

The included guider rings and dovetail saved me a ton of setup hassle—it mounted perfectly on my rig in minutes. The image is crisp and it locks onto guide stars effortlessly, even at f/4. Just what my imaging train needed.
