Since then, I've obtained 6mm, 4.7mm, and 3.7mm Ethos eyepieces, so I sold the PowerMate because I no longer needed it to get close to 500x.
Your experience with the 4X PowerMate doesn't surprise me.

Nice! I too have shorter Tele Vue f.l. eyepieces to choose from now. The 4x Powermate/35 Pan combination was heavy and is OK for high altitude viewing but anything low and I need to counterbalance. Still got the PM in case I need for photo or want to recreate the visual experience.
