Celestron Eyepiece FOV

[Crossway]

Re.  Celestron eyepieces as supplied with their Astromaster scopes,  I would like to know what the Apparent  FOV is for the 10 mm eyepiece and wondered if  someone could help please.

Their manuel states that the 20mm FOV is 50 degrees  but no mention of the 10mm.   

Thanks

Pete, I don't know for sure but I would assume the 10mm is 50 degrees afov too, it's a fairly common spec for these supplied eyepieces.

Just held both my stock 20mm & 10mm up to view through them, and the 10mm seemed slightly larger, perhaps 55 degrees at most. Just a rough estimate only though.

Thanks for helpful replies  Chaps,   was a bit confused by info. in Astro. book  with suggested  approx FOV of  30 degs. for general EPs. which was  very contradictory to the Celestron figure  for their own  supplied unit, which must be correct of course.
