HI flearosie,
I would stick with the ep's you have for now - they will provide magnification of 30 (for 40mm), ~50 (25mm) & 120x(10mm). I would use the 40 or 25 for cruising around & use the 10mm to zoom in on planets / finer detail. Before buying try a few other peoples diff ep's, you will see what your ep's deliver, and what might be better for you etc.
