So here is my revamped Eyepiece case. New acquisitions are the Powermate (2x), the Astronomik OIII filter (greenish box), the ridiculous low costing W Optics SPL 6mm (couldn't resist), the Radian 5mm and the shining light Nikon Nav-17HW. The box laid flat next below the 6 filter cases contains the EIC to turn the Nikon into a 14HW. I am keeping the Vixens, both to provide for narrow field viewing if ever needed for cutting out bright stars etc and the 15mm NLV also fits into my 60mm spotting scope where it sits really well. So that's 7/8 eyepieces, 11 usable focal lengths when I throw the Powermate into the equation.
