Primary Mirror Shutter

Finally, no more worrying about dust settling on that massive mirror between sessions—the remote functionality alone saves me from climbing a ladder. I was honestly surprised how smoothly the four vanes open and close every single time.

The four-vane closure is rock solid—no creaking or misalignment even after a year of weather swings. Remote control works flawlessly from my phone, which means I no longer have to climb a ladder to check if it's sealed tight. Dust and moisture haven't touched the glass since install.

I was worried about dust getting on the mirror during remote sessions, but this shutter’s four-vane design closes securely and smoothly. It’s a relief to control it remotely and know the optics are protected between uses.
