    Albert:
    Are there any plotted objects on the SA 2000 that simply can't be seen? I'm
    thinking of some of the larger nebulous regions, for example.

    I didn't set out to complete the H400, but I completed it within less than
    1-1/2 years. My goal was to observe everything plotted in Sky Atlas 2K above
    a reasonable declination. My SA2000 project is essentially done and
    completing the H400 list was a natural consequence. I checked off a large
    fraction of the H400-II list as well. In the original edition, only one H400
    object was missing. It was added in the recent edition. So, I'm sure the
    H400 can be completed within a year.

    I personally wouldn't recommend sketching all objects on the H400 list. For
    that matter, I don't recommend hunting down everything on the list. A large
    fraction are fairly uninteresting in my 12.5" scope and you miss so much by
    jumping to only those objects. Using the SA2000 as a guide, I covered much
    more of the sky, and found much more interesting objects, including objects
    not plotted.

    I think there is merit to compiling a list of interesting non-Messier OC's.
    I would add other objects as well. In fact, I have started such a list. My
    goal is to indicate what are interesting objects viewed through a 12.5"
    scope. I created the list by reviewing my observing notes. Next, I plan to
    revisit each object to make sure it belongs on the list.
