Could someone tell me what and where a triangle with two separated stars at each corner is?

 

Thanks!

This maybe ... ?     https://en.wikipedia...i/Epsilon_Lyrae

Are you thinking of the Orion trapezium perhaps?

Four easy stars, two hard to see less bright stars and even four very faint stars about mag 15.

Can you at least tell us what section of the sky you were pointing in, NE, NW, SE, SW, above or below the celestial equator and the time and location from where you were viewing from...etc?

Rather too broad for anything specific, really.  Pick any two double stars, and another star that's not on a straight line, and there you have it.  The number of such things decreases as you start putting limits on the field of view the two doubles fit in.  It's rather likely you'll find another star in that field with enough aperture.  Even double double three and a half minutes apart has 13th mag stars between them.

Your question implies a double star at three different locations. Is that what you're asking? Please be clear.

Exactly.  I will be set up in a Bortle 4 in a few weeks and will attempt to find it again.

All were about the same brightness and it was striking the geometric perfection - not off even a bit (from our vantage point on earth)  There were no stars between (or very low brightness)  This really looked like a triangle with two stars on each point.

Hi PhotonSeeker. What you're seeing is the cool little asterism that is inside the Hyades open cluster in Taurus.

Thanks!

definitely Hyades.

[james7ca]

That grouping in the Hyades doesn't look very impressive in SkySafari since there are two more magnitude 6 stars that appear around that asterism and one of the "doubles" contains a star of magnitude 6.5. So, you've got the "triple double" that vary widely in magnitude plus two other stars and all eight form something of a rough circle or diamond shape. Below is the screen shot from SkySafari of this asterism in the Hyades.

Good Morning!

For all the time I have spent in Taurus, this fine binocular asterism was never on my radar...slightly untrue...I have images from a number of years back of the area that I I have annotated to share here, but with this post it is now engraved on my brain!! 

 

Binoculars are likely the best tool to appreciate this star grouping or a wide rich-field scope...a quality 50mm finder scope should also do a nice job.

 

Cheers, Chris.
