Space Arcade Collimation Cap – 1.25″

Unlock Pinpoint Precision for Your Newtonian Telescope.

Product Overview

Is your Newtonian reflector delivering soft, underwhelming views? The secret to crisp, high-contrast celestial images is perfect optical alignment, or collimation. The Space Arcade Collimation Cap is the essential, a simple tool designed to make this critical task fast, easy, and accurate, even for first-time telescope owners.

Forget the complexity of expensive lasers or intricate Cheshire eyepieces. Our Collimation Cap is a simple, yet highly effective accessory that slides directly into your 1.25″ focuser, guiding your eye to the exact center point. By creating clear, concentric reflections of your mirrors, it allows you to quickly adjust your secondary and primary mirrors for optimal performance.

Bring your stars back into focus and enjoy the sharp, breathtaking views your telescope was built to deliver—the easy way, with Space Arcade.

Key Features

How It Works: Simple Steps to Perfect Alignment

The Space Arcade Collimation Cap is based on the proven principle of visual alignment:

1. Insert: Simply insert the Collimation Cap into your telescope’s 1.25″ focuser drawtube, just like an eyepiece.

2. Look: Look through the small, central pinhole.

3. Align: Adjust your secondary and primary mirrors until all the reflections you see (the secondary mirror, the reflection of the primary mirror, and the reflection of the cap/your eye) appear as a single set of perfectly concentric rings.

When the rings are concentric, your telescope is perfectly collimated and ready for optimal viewing!
