NGC 884/869 - Perseus Double Cluster
Introduction | Map | Sketch | My
Observations | References
On this page I collect my observations of the double star cluster NGC
884/869 in the constellation Perseus.
The open double star cluster NGC 884/869 in Perseus is
considered to be a first-rate deep sky object. Therefore, it has received
a 5-star rating from Stoyan. Supposedly the double cluster should be seen
with the naked eye, but I cannot confirm this. In small binoculars, however,
it can already be seen well - particularly, as a double cluster.
Size: 25' / 20' (Stoyan)
Distance: 7,600/6,800 light years (Stoyan)
Ranking: ***** (Stoyan)

provides a rough impression of what I observed (my impression was much fainter
than the sketch):

My Own Observations
Observations Summer to Autumn 2016
of October 2016 (Sumène, Haute Loire, France: Heritage
100P, LT binoculars): Observed Perseus Double
Cluster NGC 884/869 with Heritage
100P at various magnifications (both together at low magnifications
and one at a time at higher magnifications) and using binoculars - beautifully
seen, they were sparkling (but there the sky is particularly dark).
Observations February/March 2017
- February 15, 2017: (Mühlhausen/Kraichgau: Heritage
100P on GoTo mount,
LT binoculars): Using the GoTo mount revealed that I probably saw more
or less both clusters when I tried to observe the Perseus double cluster NGC
884/869. At first, the star clusters appeared faintly, later they
were better to see, but never as beautiful as we saw them in France in
autumn 2016, where they sparkled. But there the sky is particularly dark.
- February 18, 2017 (ditto: GSD 680):
Once again looked for the double cluster NGC 884/869 with the GSD
680, and with this telescope I was able to recognize the double cluster
- March 16, 2017 (ditto: Heritage P130 on GoTo mount):
Observed NGC 884/869, but did not take any notes...
Observations September 2017
