Hey!
Does anyone has experience with these eyepieces in this scope? I can't find information about them in the official webpage (http://www.ricoh-imaging.co.jp/english/products/binoculars/scope/xw/index.html), which might be an indication that these eyepieces are not intended to be used in spotting scopes?
What's confusing is that in various sellers pages I see: XW 3.5mm, 5mm, 7mm, 10mm, 14mm, 20mm eyepieces may be used with Pentax PF series Spotting Scopes (except PF 63 Zoom).
According to the 50x/inch rule, the PF80ED-A highest useful magnification should be 157.5x, so the 3.5/5mm eyepieces should work fine (148x and 103.6x considering a scope's focal length of 518mm).
I ask all these with the idea of using those short focal length eyepieces for astronomy (watching the moon and planets).
Any suggestions?
Thanks a lot!
Pedro
