Hello all,
I am looking for a low magnification, widefield eyepiece for use on a Celestron C8 SCT f/10, using the 1.25" diagonal - I don't want to get into the realms of 2" eyepieces. I was looking at the Celestron 32mm Plossl, but with its 52 degree AFOV, it would give a true field of view of 0.82 degrees; bearing this in mind, a 24mm Baader Hyperion with its 68 AFOV gives a true field of view of 0.8 degrees. So to me, they would both show the same 'patch of sky' but the Hyperion would do it with a greater magnification, and so would be preferable - or am I missing something?

Thanks,
Trev

You've got it Trev. 24mm wide field eyepieces do show as much sky as 32mm "standard field" eyepieces like plossls.

The extra magnification helps darken the background sky a little which can help pick out fainter deep sky objects.
