Observing Tips

If possible, observe at a dark location and when the Moon is not bright. A bright Moon will make it more difficult to see the stars and impossible to see clusters, nebulae and galaxies. Only a small telescope at lower magnifications, around 50x, is required to see the objects listed below. The planets and Moon are best observed with a telescope around 100x.

Clusters, Nebulae & Galaxies

 Alpha Persei Cluster. Distance: 600 ly / Diameter: 31 ly / Mag 1.2.

 Andromeda Galaxy. Companion to our Milky Way Galaxy. Distance: 2,400,000 ly / Diameter: 120,000 ly / Mag 3.5.

Castor Double Star. Favourite double star. You’ll need a telescope with 50x to 100x to see Castor separate into two stars. Magnitudes of two stars are 1.9 and 3.0.

Double Cluster. Two side-by-side clusters. Distances: 7,200 ly / Diameters: 63 ly / Mag 3.5. Best in a telescope but visible with eyes in dark skies.

M35. Cluster. Distance: 3000 ly / Diameter: 24 ly / Mag 5.

M34. Large Cluster. Distance: 1,400 ly / Diameter: 14 ly / Mag 5.2. Try with binoculars, too.

M36. Cluster. Distance: 3,700 ly / Diameter: 13 ly / Mag 6.0. Try with binoculars, too.

M37. Cluster. Distance: 4,200 ly / Diameter: 29 ly / Mag 5.6. Try with binoculars, too.

M42. Orion Nebula. Brightest nebula in the northern sky. About 30 ly in diameter and 1,760 ly away.

 M44. Beehive Cluster. Distance: 610 ly / Diameter: 16 ly / Mag 3.

 Pleiades. Cluster. Spans about 2° in sky or 4 Moon diameters, Distance: 440 ly / Diameter: 15 ly / Mag 1.2.
