This eyepiece is engineered to deliver a relatively low magnification with a wide field of view, making it ideal for taking in wide swaths of the night sky for deep-space visual exploration
This reducer / field flattener is designed to work with the Altair Astro Wave 150EDF refractors with 3.7" focuser. It has an M48 rear thread adaptor for connecting your DSLR or CCD camera.
The Altair 2" premium diagonal with positive-lock system grips 2" accessories tightly with a small rotation of the top knurled ring, keeping them precisely centred.
