Apertura 1.25" Collimation Cap
A Simple, Effective, Cap With Quality That's A Cut Above The Rest!
Collimation caps are one of the simplest, if not the simplest, tools available for aligning the mirrors in your telescope. There's no laser beams or metal crosshairs here, but don't let that fool you -the Apertura 1.25" Collimation Cap can set you up for great views just the same. If you're looking for a basic collimation tool with a premium build and a great value, this cap is what you need!
Apertura knows that "simple" doesn't have to be synonymous with "cheap". Unlike other collimation caps which are made from plastic and reflective stickers, the Apertura 1.25" Collimation Cap is machined from solid aluminum with a bright reflective ring. This cap fits in 1.25" focusers, or 2" focusers with the use of a user supplied step-down adapter. For those looking for a dedicated 2" focuser collimation tool Apertura does make this cap in a larger size!
Designed for Functionality and Durability!
Aligning your optics is crucial for getting the most out of your telescope. Apertura designed the 1.25" Collimation Cap to maximize effectiveness and build quality, making this a great and essential tool that you can use again and again.
Solid Construction, High Contrast Design
This cap’s solid, single piece, aluminum construction makes it more robust than most other offerings on the market. The cap is extremely durable and has a premium feel. Where other designs use a simple sticker with a hole, the Apertura 1.25" Collimation Cap has a polished bottom ring, resulting in a bright machine finish. The center section has been darkened to increase the contrast in use. Ultimately, these features make this collimation cap easier to use than the competition!
Compatibility, Confidence
The 1.25" Collimation Cap works great with Newtonian telescopes, and Apertura has created a detailed guide for this tool that will have you up and running with these telescopes in no time! In addition to Newtonians this cap can also be used to help dial in collimation on popular RC telescopes, making it a versatile addition to your telescope toolkit.
