andromeda galaxy
I am newcomer to astronomy. I have a 6" Newtonian relector f/5. it was
supplied with a 25mm wide angle lens & a 10mm lens. I have spent some time getting to know the constellations & feel that I have a fair idea as to where everything is located. Over the last few night, I have been trying to observe the Andromeda Galaxy. I have studied star maps & I am sure that I am looking in the right area of sky. I have located the square of Pegasus, then from the star at the top left I have counted two stars to the west. Then from there, I look about a third of the way towards Cassiopeia, where I see nothing. Am I looking in the right direction, & if so, which of my eye pieces should I use & expect to see. Thanks to anyone for your help. |

Thanks to anyone for your help. I must assume you live in a light polluted area, since Andromeda Galaxy is an easy naked-eye object otherwise. Your best bet is to use binoculars to identify the galaxy (piece of cake!), and using the same binoculars, "walk" from Pegasus to the galaxy. Once you know how to get there, you can star hop with the scope and a low power eyepiece. Remember to count the star in the square as one, then go to the next (an orangish star). If your skies are dark enough, there is another fainter chain of stars that seem to arise from the square of Pegasus, but diverges from the bright chain. From the second star from Pegasus, go to the star directly above it. Then keep on going in the same direction about the same distance, and you will find another fainter star and the galaxy in the same field of view. As to what to expect: an elongated glow, not much detail. At low powers, yhou should also see M32 and M110 above and below the main galaxy, two small, roundish blobs of light. Higher powers and larger scopes will start to show some detail in Andromeda, such as a hint of the lanes and a few clumps. Any scope 25 cm or above can show at least one of Andromeda's globular clusters (but you will need a good map and ideal skies), if not more. With binoculars and dark skies, the galaxy is some 6-8 times longer than the moon is wide. Hapopy hunting. Kapella |

The Telescope Finder Scope should see almost the same thing as the Binoculars, maybe a bit dimmer but you'll see it. -- Michael A. Barlow |

(at least not if your sighting conditions are compareable to mine) Study the area, someplace you will have the feeling that there is 'something', some sort of faint glow, but when you look exactly at it, it will vanish into the dark. Move your look ~ 1/2 degree sideways (~moon diameter) and the faint glow is there again. Now you have it, that's Andromeda galaxy. Pull out your scope, use the longest eye-piece you have (for small magnification) and point it to this magic spot. -- Karl Heinz Buchegger |

Thanks to anyone for your help. In addition to the other responses, I'd like to say that if you are just starting, M31 isn't the best looking object for a new astronomer, especially from light polluted skies. If you didn't try it yet, look at M42. Regarding the eyepiece - use the lowest power you have (the EP with the longest focal length), at least initially . This will show you wider field of view and the core of the galaxy will probably be easier to discern. For M31, do not expect to see anything more than an elongated smudge in the beginning, especially if your skies are not very good. What you will be seeing is the brightest central part. With some experience, especially from darker sites, you will be able to see at least one dark lane and possibly some more details. Regards, - Alex |

According to astronomical studies (from science channel ) here in
California, Andromeda galaxy is on collision course with Milky way, our own galaxy and are moving towards each other at 250,000 miles per hour. "helen abdullahi" wrote in message ...

Since you are a beginner I would use the 25mm eyepiece as it will show a
wider field of view. For a beginner Andromeda, and any other object, can be somewhat of a challenge. But it should be easy once you know where it is. it took me a while to find it on my first attempt. It just takes patience and practice. Remember your scope only shows a relatively small part of the sky. You probably are looking in the correct "general" area of the sky but if all you see are stars then you are not in the "exact" area. Double check your charts and make sure of the general area. Check that your finder scope is properly aligned with the main scope. You should expect to see an obvious elongated fuzzy spot with significant brightness in the center. Also much larger than the surrounding stars. Just sweep the sky slowly. Go back and forth and up and down in a generous area making sure not to skip any space. Kind of like painting a solid square. It is there and with a 6" scope it will show up good. Just keep at it and dont give up. Also another good object for beginners is M42 in Orion. "Rap" wrote in message ...
