NLO Check List - Perseus





M76/NGC650 – Planetary Nebula – Moderate
Often called the little dumbbell nebula this bright planetary nebula looks more like a rectangle at low magnification and a figure 8 at higher magnification. Using a filter improves the contrast.

NGC869/Collinder 24/Melotte 13 – Open Cluster – I3r – Easy
Part of the famous “Double Cluster”. Can be seen with the naked eye and enjoyed through binoculars or any sized telescope. Just take your time and enjoy these superb clusters and their rich surroundings!

NGC884/Collinder 25/Melotte 14 – Open Cluster – I3r – Easy
The other part of the famous “Double Cluster” also known as Caldwell 14, enjoy!

Collinder 29/Trumpler 2 – Open Cluster – II2p – Easy
This is a large open cluster that lies close to the double cluster. Through binoculars or any sized telescope this is a joy, look for chains of stars.

NGC1023 – Spiral Galaxy – Moderate
This is a bright spiral galaxy that can be found on the border of Perseus and Andromeda, find Algol in your finderscope then follow a chain of stars to the galaxy. Through moderate sized scopes a bright core will be seen.

M34/NGC1039/Collinder 31/Melotte 34 – Open Cluster – II3r – Easy
Another nice open cluster than can easily be found. It is roughly the size of a full moon and is best enjoyed through binoculars or small telescopes. Using a large telescope will lessen the impact of this cluster due to its size. Look for some nice pure white stars nears its centre.

Perseus Contd

Collinder 39/Melotte 20 – Open Cluster – III3m – Easy
Using binoculars will show a wonderful star field lying between alpha and delta persei. This cluster is part of the Alpha Persei Moving Group which contains over 100 stars.

NGC1342/Collinder 40/Melotte 21 – Open Cluster – III2m – Moderate
Visible in binoculars under dark skies this is a bright but loose cluster of 8th to 14th magnitude stars scattered in chains and loops. Through larger telescopes under low magnification look for a long stream of stars going east to west.

NGC1491 – Emission Nebula – Moderate
This is a small moderately bright emission nebula that is best viewed through a filter. Using averted vision will reveal detail.

NGC1528/Collinder 47/Melotte 23 – Open Cluster – II2m – Moderate
Under dark skies this could be a good naked eye challenge. This cluster is a marvellous sight through all types of equipment. Small binoculars will reveal many cluster members but increasing size and magnification many stars forming arcs and chains will appear.

NGC1582/Collinder 51 – Open Cluster – IV2p – Moderate
This is a large scattered cluster of stars ranging from 9th to 13th magnitude. What makes this cluster interesting is its impressive arcs and chains of stars including one chain of stars over 20 arc seconds long.

NGC1495/Collinder 44 – Open Cluster – III2p – Moderate
A small indifferent cluster even when seen through large telescopes but what makes this cluster interesting is that it has 2 nice features, one in the shape of a semi-circle and the cluster is divided into 2 groups.

STF331 – Mag 5.2/6.2
A nice double star, both stars are blue-white but look for the companion star which is much dimmer

15 eta “Miram” STF307AB – Mag 3.8/8.5
This star double star is one of the best contrast doubles after Albireo. It is easy to locate and look for a Golden-Yellow primary with a pretty blue-white companion
