Messier 35 (M 35)

On this page I collect my observations of the open star cluster M
35 in the constellation Gemini / Twins.
I did not know the Gemini / Twins constellation so far, but recently
a friend pointed me to Castor and Pollux, a pair of stars, which can be easily
found at the nightly sky. The older form of the Gemini constellation reminds
me of a jug lying on its side. I can therefore remember this and use it as
an aid for finding the open star cluster M
35, which is supposed to be visible even to the naked eye. M 35
is, however, located on opposite (open) side of the jug (on the right) above
the last star of the constellation (which somewhat "turns upwards" =
the "spout"). Read more on how to find the cluster below.
M 35 is said to be the open star cluster with the most stars in winter.
Size: 28' (Stoyan) - about the size of the moon
Distance: 2,600 Light years (Stoyan)
Rating: **** (Stoyan)
M 35 at the upper right edge of Gemini / Twins
May 2017: M 35 above the right upper end of constellation Gemini/Twins.
At this time of the year, it was turned to the right for nearly 90 Grad,
so that M 35 was located at the bottom right of the constellation.

My Own Observations
Observations February 2017
- February 13, 2017 (Mühlhausen/Kraichgau: Heritage
100P, LT binoculars): Despite many efforts with the 100P and binoculars,
I was not sure about whether I had indeed found M 35. There was
something glimmering in the area, but that could also have been a part
of the Milky Way, which is in that region. Perhaps, I had also searched
for M 35 at the wrong location...
- February 14, 2017 (ditto: GSO GSD 680,
LT binoculars): With the 8" Dobsonian, however, I found M 35.
The open star cluster looked very nice and showed many stars (it is said
to be the open star cluster with the most stars in winter).
- February 15, 2017: (ditto: Heritage
100P on GoTo mount, LT binoculars):
I was, of course, able to access the star cluster M 35 directly
and found it. At the beginning, M 35 was hardly visible, because
the sky was too bright. But later, when it was darker, the cluster was
beautiful, too, and showed lots of stars in this smaller telescope even
with a 7 mm eyepiece.
- February 18, 2017 (ditto: GSO GSD 680):
In the GSD 680 telescope, M 35 appeared again rich of stars and
- February 26, 2017: (ditto: Heritage
P130 on GoTo mount): The
sight of M 35 with the P130 was very nice as well (new moon).
- March 16, 2017: (ditto): M 35 observed once again
Observations End of March 2017
- March 29, 2017 (Mühlhausen/Kraichgau: Heritage
P130 on GoTo mount):
Found M 35, nice! Visited M 35 later again and again, nearly a "standard" for
Observations April/May 2017
- April 29, 2017 (Mühlhausen/Kraichgau: Explorer
150PDS on GoTo mount): M
35 beautiful, but located far in the West and fairly low at
- May 9, 2017 (ditto): M 35 located far in the West and
fairly low at the horizon and therefore, it got more and more difficult
- May 12, 2017 (ditto): M 35 not found, sky too bright
Oberservations December 2017/January 2018
- December 12, 2017 (Mühlhausen/Kraichgau: LT and TS binoculars):
Saw M 35 as a shimmering spot
- January 10,
2018 (Mühlhausen/Kraichgau: TS): M
35 seen with binoculars as a shimmering spot
- January 14, 2018 (ditto): M 35 seen with binoculars as a shimmering
spot, this time a little bit larger and better...
