In the March/April edition of "Australian Sky and Telescope", Sirius Optics are advertising EP's described as "FMC 66 degree wide angle eyepieces with 16mm eye relief" in sizes 6, 9, 15, and 20mm sizes for $55.00 each. While is doesn't specify whether 1.25" or 2", I am presuming that they are 1.25".
Does anyone have any experience of these EP's?
I am thinking about the 20mm, to be used in a 150mm diameter Newtonian, 1000mm length - ie just over F6.
I need the longer eye relief, as I have to wear glasses at the telescope.
