2. M33, Triangulum Galaxy

Distance: 3 million ly
App. Magnitude: 5.7
App. Dimensions: 71'x42' (cf. telescope field of view 119')

Notes: The detail in the disk itself is good. Our polar alignment was only so-so, even though we spent two hours on it. We needed to do at least one more iteration. Our two star alignment was good. The stars are not very round, probably because we balanced the weight on the wrong side. We need to improve the focus. Zoom in/out with ⌘↑(+/-) (Mac), ctrl (+/-) (PC).
