Do you consider the Milky Way an individual
object? If not, then what about M31?


Big swath Milky Way shots have never interested me. M31 is an

exception to the deepsky rule, they can trace it to over 5 degrees,
but not many other objects approach that size.

The Milky Way does. But that means you're not
Interested in details in your objects. If M31 was,
say, four times closer you'd lose interest in it too.

It would seem that individual objects would call for longer focal lengths and therefore more detail.

You seem to have amazing mind-reading abilities there, dude.

I'll not speculate on how Rich might react to a 4x closer M31, but I'd say that (for me) the M31 globs would be a must-see.

If M31 were 4 times closer, it would be a spectacular view in a moderate aperture telescope at about 75x and an eyepiece with about a 1/2 degree field of view.

FYI: the apparent length of M31 in our sky is some 3 degrees. If it
was 4 times closer it would appear 12 degrees across. A field of view
of just 1/2 degree would then only show a small part of it.

So? The details in M31 would be more apparent in any given telescope, binocular or camera.
