Astro Imaging

The Orion 2" Multiple 4-Filter Wheel is a rotatable 2-inch filter holder for those deploying telescopes with 2-inch-fitting focusers, who wish to make full use of large format sensor illumination for tri-colour imaging - or alternatively for those have 2" eyepieces for visual observations. Holding up to four filters, this is a reasonably-priced, non-motorised alternative to the more expensive Nautilus focus wheels from Orion. Learn More
