I've done some further reading on exit pupil and now understand that due to my scope being f10 that a lower powered eyepiece will yield a brighter image.
I dont mind spending a decent amount of money on a quality eyepiece which would be my workhorse, i just need to know what focal length to get. If i was to get a 25mm eyepiece this would mean the exit pupil would be 25 / 10 = 2.5mm. With a larger focal length eyepiece wouldnt there be a trade off of not having enough magnification?
Im 26 and my eyes are in good shape so im assuming the diameter of my dialated pupil will be somewhere in the region of 7mm. I realise now that for general viewing and the use of a filter will need a longer FL eyepiece as well, what FL eyepiece i should get?
