Triangular Asterism in Pisces new
      #5433684 - 09/21/12 11:52 PM

I just happened upon a very attractive asterism in Pisces at RA 23h16m36s, DEC -01deg35m12s. It's a near perfect equilateral triangle of three stars with a fourth star in the center. East of the triangle is a line of three stars pointing to it. Looks best at low power (20x - 30x). Stars are mag 7 and 8. Reminds me of the Stargate asterism.

Is anyone familiar with this one? I haven't seen it mentioned in any of the asterism lists I have. It's an instant favorite of mine now.

The only one I'm aware of in Pisces is the Circlet". Could be you've found another.

Thanks for posting Chemist

If it helps others to find it, the attached is drawn from the AASVO plotter using your above given Ra/Dec. Co-ordinates.

FOV 1.5 degs.
North is uppermost: East is to the left.
Faintest stars to magnitude +13.

You certainly have found another Chemist.

Now we need a name for it. "Rocket ship" ? The three stars in a line being the booster flames out the back.

Regards. Peter.

Good one Peter !

I have to say that I was thinking along the same lines when I produced that plot and on seeing it, thought of naming it "Chemist's Kite" !

Best regards,
Tel

Cool! Reminds me of the Stargate (asterism) in Corvus as well. Except instead of a single star in the center of the triangle, the Stargate has another much smaller triangle of stars rotated about 45 deg from the outer one. Anyone iterested in the Stargate, the location is: RA 12h 35m 59s, Dec -12 03'09".
Wikipedia article: http://en.wikipedia.org/wiki/Stargate_(asterism). Seeing the whole thing requires dark skies as the dimmest star in it is about Mag 11.5. Good hunting!

One more thing ...
The center star is actually a double, WDS STF2995, 4.6" sep.
It just keeps getting better.
The more I look at it the more I keep thinking "rocketship" rather than "kite".

The Wiki address isnt working.

http://en.wikipedia.org/wiki/Stargate_(asterism)

Try this one

I have never seen this one and in searching for info I found this. That area has some interesting tidbits.

I "found" this many years ago in 1974 while looking at a picture of Comet Kohoutek in the April 1974 issue of S&T. I have always called this Kohoutek's Arrow since the comet passed almost right over this on Jan 20, 1974. Visually it is pretty nice. This has never been listed on any asterism lists as far as I can tell. But it is worth finding. Someone mentioned Rocket Ship which is what I always see when looking. The short line of three stars certainly make it look like it is giving the "Rocket" flight
