Question

You decide to look for the supernova yourself. You have a telescope with a focal length of 1m, and you have three eyepieces with focal lengths of 4 mm, 10 mm and 20 mm respectively (all with an apparent field of view of 43 degrees). You decide to start by finding ξ 1 Cen (about 20 arcminutes from NGC4945), and navigating from there.

a. Which eyepiece will give you the highest magnification and what is this magnification?

b. Which eyepiece will give you the widest field of view? Will you be able to see both NGC4945 and ξ 1 Cen in this eyepiece at the same time?
