Once again it is time for observation submission for next month. I need them
for the 25th in order to complete the column in time for the NL release. As a
reminder here’s the article about the observations of interest -
Now for October we’ll visit Sagitta, Pegasus and Aquarius. First is Sagitta
and an open cluster that probably isn’t on many observing lists. It is Harvard
20 and since it isn’t that well known here are the coordinates RA 19 53.1 Dec
+18 21. It is in a rich Milky Way field and doesn’t stand out well so a finder
chart would be helpful. Next is the globular cluster M 71 another favorite and
should be easier to find than the prior object. Moving on to the Great Square
of Pegasus. Before starting here’s a naked eye project. How many stars can
you see in the square? Give us a count on your observing report. We will
start with the globular cluster M 15 but come back to this constellation. The
next constellation is Aquarius and we start with another globular cluster - M
2. Lord Rosse reported seeing a dark area near the core. Do you? Next is
then Saturn Nebula NGC 7009 and its blue-green disk. What color or color do
you see? The low surface brightness NGC 7293 the Helix follows. Don’t forget
to try your filters on these two. Now back to Pegasus and the spiral galaxy
NGC 7479 which is the brightest in a group that is part of Arp 13. This one
should show a good bit of detail so spend some time here. Next is another
spiral NGC 7448 that is much smaller and fainter than the prior galaxy yet
should also show some detail. Last of the galaxies is NGC 7454 an elliptical.
It too is rather small and faint. Our final selection is a rather rare, for
Pegasus anyway, open cluster. It is the scattered NGC 7772 that contains
several faint stars.
