Whats this double

[ZOG]

I got an hour outside tonight before the rain started, I was checking out how the scope performs on splitting doubles. After looking at the belt stars in Orion I panned south a wee bit and saw what looked like a dimmish star with a faint companion in the 32mm. I dropped the 10mm EP in and was suprised to see the companion split into a double itself. Having been used to goto I am now learning the sky with the dob so I'm not as knowledgeable as some.

I've been looking at stellarium and the closest I can see to where I was looking is un named and has RA/Dec 4h 45m 36 3 0'37 and is slightly south of hip22137. Trouble is stellarium shows the faint double at 12oclock to the brighter star and what I was looking at showed the double at 2oclock.

Can anyone identify this one for me please.

sigma orionis? is actually a quadruple - you an see all 4 components reasonably easily at about 150x in a 6" newt (and easier in a 10" )

It does sound like Sigma Orionis. If it was just below the lefthand star of Orions belt then it sounds the best candidate

Sigma Orionis ?? I dont know but I'll check with stellarium. It seems strange that I only made out 3 components in a F5 12 inch scope though.
