Why should I upgrade to the Starlight Instruments 2" Dust Cap from the one my telescope came with?
Standard plastic caps can crack, warp, or provide a loose fit that allows dust to enter your optical train. The Starlight Instruments 2" Dust Cap is machined from durable, anodized aluminum for a secure, long-lasting seal that offers superior protection for your optics.
What is the Starlight Instruments 2" Dust Cap made of?
The cap is made from high-grade aluminum. It features a black anodized finish for durability and is finished with a laser-scribed Feather Touch® logo.
Will this 2" dust cap fit my Feather Touch focuser?
Yes, absolutely. This cap is designed to provide a perfect fit for Starlight Instruments Feather Touch focusers and any other focuser, diagonal, or accessory with a standard 2.0" opening.
Can I use this Starlight Instruments cap on my 2" diagonal when an eyepiece isn't inserted?
Yes, it is ideal for this purpose. Placing the cap in your 2" diagonal protects the mirror or prism from dust when your telescope is not in use, ensuring it's clean for your next observing session.
Does the anodized finish on the 2" dust cap prevent scratches?
Anodizing creates a hard, corrosion-resistant surface layer on the aluminum. While not scratch-proof, it is significantly more durable and resistant to scuffs and minor abrasions than paint or unfinished metal.
Is the Starlight Instruments 2" Dust Cap just for telescopes?
No, it can be used to protect any piece of equipment with a 2.0" opening. This includes accessories like Barlow lenses, extension tubes, and camera adapters that you want to keep free of dust during storage or transport.
