- Description
This accessory is designed for use with our Daystar Combo Quark Hydrogen Alpha Filter.
Our most powerful focal reducer, the 0.33X Tilt Reducer allows smaller image sensors to still fit the maximum field of view possible. Depending on telescope focal length, full disk imaging may by possible even with small sensors. Exposure times will be approximately one ninth as long as without the reducer. Due to the faster focal ratio, the interference fringes are reduced, so little to no tilt may be required.
The Daystar 0.33X is also designed for 17.5mm backfocus cameras, or 12.5mm in combination with the 5mm spacer.
