This week I captured the last two Messier objects on my list completing my version of the Periodic Table of Messier Objects with the 6SE. The table is flanked on either end by M16 and M42 - the two objects I enjoyed imaging the most. On the left are globular clusters with the highest brightness on the top and decreasing going down and to the left.
Oct 6, 2008 · Thanks, Surface Brightness and Messier Objects - posted in Deep Sky Observing: My recent inquiry about surface brightness in these forums produced a lot of useful information on the subject, which before this, I had a rather poor understanding of it. While still looking for more info on the subject on the web, especially about how to utilize SB ...
The Messier catalogue is one of the most famous lists of astronomical objects, and many objects on the list are still referenced by their Messier numbers.[1] The catalogue includes most of the astronomical deep-sky objectsthat can be easily observed from Earth's Northern Hemisphere; many Messier objects are popular targets for amateur astronomers.

Put simply, it’s this: The Messier 110 (or just M110) is a catalog of 110 night sky objects that were discovered by a French astronomer called Charles Messierin the late 1700s. He found them as a result of his attempts to find comets in the night sky. Over 100 hundred fuzzy objects appeared in his telescope that he couldn’t explain, but he knew the...
The Messier Catalog consists of 1 asterism, 29 globular clusters, 26 open clusters, 1 double star, 39 galaxies, 1 Milky Way star cloud, 7 nebulae, 4 planetary nebulae, 1 supernova remnant and one which is “not certainly identified” (M102). You can find the detailed breakdown behind these numbers on this Wikipedia page. They vary in brightness, inte...
M31, Andromeda Galaxy, Andromeda
It is something quite amazing to see the Andromeda galaxy through your telescope. If you never have, then read ourbackyard astronomer’s complete guide to finding Andromeda. In reality, we can’t resolve it to with a backyard scope to the quality of the picture above. But, standing there and realising that you are looking at the light of a trillion stars(!) some 2,000,000 light years outside of our own galaxy is really quite stunning. There are two other Messier objects near the Andromeda galax...
M15, Globular Cluster, Pegasus
This is an ancient cluster, estimated to be some 12 billion years oldand about 35,000 light years away. Through a small telescope, you will see the bright centre of this cluster surrounded by a hazier outer region. A larger telescope will resolve individual stars in the outer reaches (there are hundreds of thousands of stars all together in this cluster)… though not to the degree of the spectacular Hubble picture above.
M2, Globular Cluster, Aquarius
Messier 2 is one of the largest globular clusters known and it’s located in the constellation of Aquarius. With around 150,000 stars, this cluster is (with ideal conditions) bright enough to see with the naked eye, but it is a challenge to locate being in a remote area of the sky. The advice is to find M2 with a wide field eyepiece and then get the best viewing of it by increasing magnification.
M42 & M43, Orion Nebula, Orion
In our Beginner’s Guide to Backyard Astronomy course, we show you exactly how to track down and observe Orion Nebula in the constellation of Orion. Shimmering around the stars in Orion’s ‘sword’, which hangs from Orion’s belt are both M42 and M43. This ‘tiny’ patch of light is actually some 20 light years across… our nearest star after the sunis only 4 light years away, so that gives a sense of scale. A larger telescope will make it possible to distinguish the two nebulae as distinct, but eve...
M79, Globular Cluster, Lepus
At 41,000 light years away from us, and 60,000 light years from the center of the Milky Way, Messier 79 is believed to be outside of our galaxy. This is a much harder find than M42 and nowhere near as spectacular, but it is rewarding both because of the challenge it gives and the ball of light it presents through your eyepiece.
M45, Pleiades, Taurus
Easily visible to the naked eye as a indistinguishable patch of light containing a ‘v’of stars, training a small scope (or even decent binoculars) on this area yields a sight which will make you say “wow!” This extensive open clusteris only in the order of 500 light years away from us and contains young, hot, blue stars by the score. Through a beginner’s scope, you’ll resolve a few dozen stars, maybe as many as 50, but they won’t all fit in your eyepiece at once (unless you have low magnific...
M44, The Beehive, Open Cluster, Cancer
On the edge of being visible to the naked eye, M44, the Beehiveis a great spot through a small telescope. Less than 500 light years away from earth, this 600 million year old cluster contains upwards of 1000 stars, of which a small telescope will resolve 30-60. Because of its size, it is best viewed on low power with a wide field eyepieceto let you take in the scale and beauty of this rich star field.
M67, Open Cluster, Cancer
This cluster of over 500 stars in the constellation of Cancer is ancient, estimated at between 3.2 and 5 billion years old. It is a wonderful find for an astronomy beginner precisely because it is such a rewarding sight through the lens of a small telescope. M67 covers a wide area of the sky and training your scope on it will resolve a number of the brighter stars, but the many fainter stars which aren’t resolved add a rewarding light to the overall area.
M65 and M66, Galaxies, Leo
This one is a little bit of a bonus: two Messier galaxies (M65 is upper right and M66 lower right in the picture above) plus NGC3628 upper left. (Which is why it’s in our beginner’s course). Together, these three galaxies are known as the Leo Triplet or LeoTrio. The reality with all galaxies is they do look better in a larger aperture telescope, but for the beginner looking to cement interest in the night sky, you can do a lot worse than getting three galaxies all in the same eyepiece view!...
M13, The Great Globular Cluster, Hercules
Summer brings the Milky Way into its best view for those of us in the northern hemisphere, meaning clusters take to centre stage of the Messier catalog. M13 is, as its name suggests, an epic globular cluster of some 300,000 stars in the Keystone at the heart of Hercules constellation. Whilst a smaller scope will not reveal individual stars like the Hubbleimage above, it will show you an impressive ball of light sitting on the central ‘square’ of Hercules. Stare in awe at a collection of stars...
M92, Globular Cluster, Hercules
Messier 92is a very bright and nearby neighbour (if not quite as spectacular) of the Great Globular Cluster. Even though it is over 26,000 light years away, great seeing can make this an object visible to the naked eye, but a small telescope helps bring it to life for us amateur astronomers. This is one to take your time at the eyepiece with, as the longer you examine it, the more distinct it will become… as ever, you will resolve few individual stars of the several hundred thousand it is bel...
M57, The Ring Nebula, Lyra
The beautiful Ring Nebula is a planetary nebula in the constellation of Lyra, and number 57 in Messier’s catalog, marks a fitting climax to our seasonal tour of Messier objects. Born out of the explosive transformation of a red giant into a white dwarf star. The bright white star at the very centre of the nebula in this picture is the star that shed the gas making this stunning vision. Using a medium powered eyepiece in a small scope will easily bring the small disc of light into view, lookin...

Aug 23, 2020 · The “ Magnitude and Contrast Calculator ” is a spreadsheet, included as a supplement to the RASC Observer’s handbook, that calculates the surface brightness and predicts whether an object is visible from telescope, filter, and sky parameters. Tony Flanders has compiled a list of Messier objects that includes the surface brightness and ...
