Dust cap for 114mm reflector telescopes

This 3D printed dust cap is designed specifically for Newtonian reflector telescopes with a 114mm outer diameter. It provides a snug fit to prevent dust, lint, and moisture from settling on the primary and secondary mirrors. Keeping the optics clean is essential for maintaining clear views and extending the life of the mirror coatings.

The cap is compatible with various models, including the Meade DS-114AT, and other tubes with the same dimensions. Unlike generic covers, this precision-fit cap stays in place even when the telescope is moved or stored vertically. The material is durable enough to withstand regular use in the field or at home.

Using a dedicated dust cover reduces the frequency of mirror cleaning, which can be a delicate and risky process. This accessory is a practical investment for any owner of a 114mm reflector who wants to protect their equipment. It is a simple, effective solution for maintaining optical performance over time.
