Astro-Tech Collimation Knobs

If you desire a no tools approach for adjusting the secondary mirror of your high-quality Astro-Tech Ritchey-Chrétien telescope, then check out what Bob’s Knobs has to offer you! Made from black plastic and stainless steel, these easy to adjust knobs will help you keep your telescope in tip top tune without any worry over dropping an Allen wrench on your finely crafted diffraction limited optics!

Combining Takahashi’s 6x Collimating Telescope as well as their 2" Sleeve for Collimating Telescope is a high precision method for aligning the optics of your Astro-Tech Ritchey-Chrétien telescope. An informative instruction manual is also included with this accessory to help guide you to near perfect collimation, allowing the full potential of your Astrotech RC telescope to shine through!

Regardless of which collimation method you use for achieving the best images of star fields, globular clusters, the Moon and planets, or just about anything with your telescope, we recommend that you perform the final collimation procedure on a star using a high power eyepiece. This will assure the sharpest images possible and allow you to discern details that may otherwise be invisible!
