Modern astrophotography sensors are extremely sensitive to light. That’s why the most minor light leak could ruin an entire night session of astrophotography.
Our filter holder is relatively similar to a product called Filter Drawer. While a filter drawer is designed with convenience in mind, this filter holder has been designed to provide a similar functionality while totally preventing the entry of stray light into your imaging train that sometimes happens while using a filter drawer.
Highlights
- Zero light leaks.
- It's probably the most affordable solution for adding a 2'' filter to a dedicated astronomy camera.
- Version 2 can also work as an adapter between threads M42, M48, and M54, commonly found in astronomy equipment. The version 1 couldn't be used as an adapter for M54 threads.
