Re: Pleiades Occultation Eyepiece Advice

If the weather is clear tomorrow evening I plan to try and watch the Moon

size eyepiece would be better, my 25mm or 40mm? I suspect the latter for
the wider FOV, but I am not sure.

Hi:

The lower the power, the better. A 40mm in 1.25 inch format really
doesn't provide much more field than the 25mm, however, and a 25 is
usually more comfortable to use. Me? Assuming it's clear (a major
assumtion), I'll be watching with a pair of Burgess 15x70 binocs.
