Hi All,
Mike,
I would keep the 10x50s for astronomy,they are a good size.
The problem with using the eyepieces from those, is they are usually not wide angle eyepieces.
Most 10x50s have a fov about 5-6 deg,which means at best the eyepieces are 50,60 deg types,not really wide angle.
Your best bet for wide angle is the 7x35,or some of the 8x40s,I have a pair of pentax 8x40s which have a 9.5 deg fov,this means the eyepieces are approx 8x9.5 = 76 deg.(I wont be pulling these apart though)
so as I said IF you want wide angle, keep an eye out for 7x35-8x40s.
Regards.John
