Conditions
IC 1396 – Open Cluster – II 2 m n – Easy
Best viewed through moderate sized telescopes but still worth searching out
through any binoculars or telescopes. This compact cluster lies south of
Herschel’s Garnett Star and what makes it interesting is that it is cocooned in a
very large and bright nebula
NGC7142 – Open Cluster – II 2 r – Moderate
In a moderate sized telescope this appears as a rich group of stars set against
the background of unresolved stars. By increasing the aperture more stars a
revealed making it a rich site in the eyepiece. This Cluster lies very close to the
reflection Nebula NGC7129.
NGC7160/Collinder 443 – Open Cluster – I 3 p – Easy
A nice open cluster that is best viewed through binoculars. This cluster is often
mistaken for a globular cluster. In moderate sized telescopes it appears as a
tight group of stars, larger apertures will reveal more stars.
NGC7235/Collinder 447 – Open Cluster – III3 p – Moderate
Not very impressive this cluster when viewed through binoculars or small
telescopes will reveal around 2 dozen 9th to 12th magnitude stars. Again the
bigger the telescope the more stars that are revealed.
NGC 7261/Collinder 450 – Open Cluster – III 1 p – Moderate
Not very impressive but some observers report seeing asterisms within the
cluster. The most popular is either a trapezium or the letter “g”. Look for a line
of around 15 stars. Some observers report seeing a strong bluish tint to the
stars.
NGC7380 – Open Cluster - I 1 m – Easy
Easily viewed through binoculars but when seen through moderate sized
telescopes there are dark lanes running through it. The cluster appears to be
surrounded by a hazy glow.

King 19 – Open Cluster – II 2 p – Easy
A small open cluster which contains over a dozen 11th to 13th magnitude stars.
Observers report that the 2 brightest stars in the cluster look like eyes!
NGC7510 – Open Cluster – II 2 p – Moderate
A lovely object when viewed through moderate sized telescopes. The cluster
consists of a number of bright rich stars in a wedge shaped formation.
NGC188/ Collinder 6/Caldwell 1 – Open Cluster – II 2 r – Moderate
Not visible to the naked eye but easily seen through binoculars it will appear as
a faint glow. Moderate sized telescopes will reveal a smattering of dim stars.
NGC0040 – Planetary Nebula – Moderate
This object can be seen through small telescopes and is best found using an OIII
filter on a low power eyepiece where it will appear as a flat featureless disk.
Under good conditions observers have reported seeing the central star with an 8
inch telescope. Using high power will reveal detail
NGC6946 – Galaxy – Moderate
This is a large but faint galaxy that is easily found. Best seen through moderate
sized telescopes using high power will bring out the galaxy against its
background.
Mu Cephei STF2816AC – “Herschel’s Garnett Star” - 5.7/8.1
A rewarding multiple star system containing “Herschel’s Garnett Star” when
viewed through small telescopes it displays a strong red colour. Bizarrely when
viewed through larger telescopes this colour is not seen.
