View Full Version : Visual Cluster in Taurus

I suppose this is actually a "good astronomy" question, but since I'm too lazy to look any more for the answer....

I can see a visual cluster in Taurus, part of the Hyades I presume, situated between Aldebaran and the Pleiades, but very close to the former. Through my telescope, there are seven bright stars (bright in c. 200x magnification, that is) arranged in three pairs plus a singleton; the outline of the whole is vaguely reminiscent of a five-sided polygon with a very pronounced vertex (the singleton; one of the pairs marks the "back" side while the other two suggest the impression of "side" points converging towards the singleton). There are, of course, many dimmer stars in the image as well.

I haven't been able to find an image of this particular asterism anywhere. Does anyone know if it has a particular designation? Or is it just a part of the Hyades? (I understood the Hyades to be a far larger asterism than I was seeing--and none of the images I found of the Hyades matches what I was looking at.)

I found it really interesting to look at, even if it's nothing special "officially"--check it out. Sorry I can't give better coordinates; it's cloudy out tonight, so I can't go back and check. I'll post them later if someone doesn't pin this down beforehand.

Do you mean the asterism made up of the following stars:

75 Tauri
80 Tauri
81 Tauri
85 Tauri
Theta 1 Tauri
Theta 2 Tauri
HIP 21029
?

Here is an image of the Hyades (http://www.seds.org/messier/xtra/ngc/hyades_more.html), the asterism mentioned by Eroica is just a bit lower than the bright Aldeberan, and a bit to the right of it, nearer the center of the picture.

Here it is as seen by Celestia;

it is simply the heart of the Hyades, which is quite a big cluster in total; this cluster is also called Melotte 25 and Collinder 50
(the name Taurus Nexus is of couse fictional)

That's weird... the picture wasn't visible until I hit reply! :o Something about the site not supporting hotlinking.

Here's another view of the asterism. Is this the one you were referring to, Ravana?

Yup. That's it, folks. Thanks.

...the "Taurus Nexus"?

That's science fiction. In science fact it doesn't seem to have a name. Care to give it one?
