I am new to observing and I have a few questions about star clusters
which I have observed.
Even with software and a planisphere, I am not totally sure about the
names of the clusters I am observing.
Direction: North- northeast.
latitude: 42 degrees
Date and Time: 11/9 9PM EST
Three clusters with Binoculars:
1. As I slowly sweep up to Cassiopeia, I see a large wide dense cluster
of many stars just below it.
It is the largest cluster I have observed.
2.
Between Mirfak and what seems to be Gamma Persei, I also see a smaller
denser cluster.
3. Diagonally right above Perseus and diagonally up left from the
Pleiads, I see two circles of star clusters. Is this a constellation or
a cluster?
What are the names of these clusters?
Much appreciated.
Bruce

Sounds like NGC 884 and NGC 869

Sweeping up from the south horizon:

Sweeping up from the north horizon between Cas and Cep:

As others have noted, the Perseus Double Cluster, usually described as
mid-way between Cas and Per.
