Quark to M-42 .33x 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 T mount 17.5mm backfocus cameras, or 12.5mm in combination with the included 5mm spacer.
