Well, l must have some interesting EP's.
When using my 2" GSO 2x barlow both my 1.25" GSO 20 and 15 EP's need racking in and only just come to focus on stars, the 15 more so with less FL.
My 1.25" Orion Edge on Planetary 5mm EP racks out considerably to get focus and its 2 to 3 time the length of the GSO's.
Doesn't make sense to me but never mind, getting a cheap 1.25 SD to test the focus range.
