    Default NGC 4051 Galaxy at UMA/CVN border



    Hello galaxy hunters,

    I have been wondering why this galaxy has not been included in the popular lists.
    My last observation has been on March 22nd with the 25x100FB bino. I've got that fuzzy with averted vision. It was to confirm my observations made before.

    Has anybody seen it?

    Enclosed find please a scan of page 26 from the Star-Guide 2000. This galaxy is also in the Uranometria 2nd edition, page 37.

    The link below indicates this galaxy as Syfert Type 1 with a supermassive black hole.

    Thee are several galaxies nearby of about the same magnitude. How can you tell which one you're looking at?

    Hello Antonino,

    this one is sitting in the string of the 4 stars. I have tried the other galaxies around as well as, but no success.

    Thanks for replying

    I'm making myself personalized star maps to find and identify that galaxy. As we know, it takes a little planning and a little work. I appreciate your feedback JG.

    When trying to sort out a field that has several galaxies, it is of course invaluable to have a good star atlas or software you can print finder charts from. Being able to visually identify the foreground star patterns while at the EP can usually take the confusion out of having multiple galaxies. Once you have your orientation, it should be much easier to star hop the field identifying multiple galaxies. In an area like the Virgo-Coma cluster, sometimes you can even use the brighter galaxies to get your bearings, and they can be used as stepping stones (basically galaxy hopping) to ID fainter members. I think where most people tend to have problems initially, is in understanding how the orientation of the star chart corresponds to their view through the EP. Just another part of the learning experience.

    Hello Alan,

    thanks for sharing your experience.

    I have quite a problem with the Viro Galaxy Cluster. When going there with my StarWatcher, I have a plan how to scan that area of sky. Then, each fuzzy gets a drawing, showing its relative position and the surrounding stars in the field of the EP.

    That side-inverted vision in the EP is whenever I am new to some area of the sky, a problem. That's why I consider first, is there any binary around, is there any orange-red star around, is there anything like an asterism.

    Best

    Hello Dublin Sky Watch,

    I have been systematically scanning UMA and CVN for binocular galaxies. Besides NGC 4051, the other catch has been NGC 3198 in the Lambda UMA area, (25x100), on Feb 7th 2011. There are those particular nights.

    It's not that hard, Declan, it just take a little planning and patience and .... hard-headedness.
    I did try to find 4051 last night, and I was almost there ..... when the clouds covered that area. I didn't get another chance, but at least I found my bearings.

    Tonino is is correct. It's just a matter of planning and repetition. Congested areas, such as the Virgo-Coma cluster require repeated visits to become comfortable with them. When you observe the same areas or objects enough times you start to become familiar with them, just like going to the same neighborhoods around where you live. By re-visiting them, you will eventually start to see the little details that you didn't notice previously. When you look at Virgo-Coma area for the first few times, many of the finer details are overshadowed by your mind trying to comprehend the sheer number of faint fuzzies you see. Initially most of them look alike, but in time, your mind will finally see the subtle differences. In time you will begin to recognize the pattern or layout of the galaxies you can see, much like you learn to recognize certain star patterns. That is when you learn to use galaxies to locate and identify more galaxies in the cluster. Of course having a good road map is imperative as well!
