NLO Check List - Cepheus Date Time Telescope/Dome 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. Cepheus Checklist Page 2 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.
