Re: (IAAC) Obj: Epsilon Ori - Inst: 10" F4.8 Equatorial mount GP/DX

Hi Barry, I checked out Epsilon Orion to see if it was a tight double, but in fact it is a very wide pair, the last official observation was made in 1986 at which time the seperation between AB was 175.5" at PA 59 deg, and mag A 1.7 mag B 10.5, in fields as rich as the Orion field it can be a challenge identifying the true B component when the seperation is as wide as this. Info was from Skymap, which uses the WDS catalogue.
Hope this is of some use to you!
Regards, Kim Gowney.

Moon presence: Great - full or very near object
Instrument: 10" F4.8 Equatorial mount GP/DX
Magnification: 25mm @ 10mm
Filter(s): None
Object(s): Epsilon Ori
Category: Other.
Class: Star
Constellation: Orion
Data: mag 1.70  size
Position: RA :  DEC :
Failed to split Epsilon Ori, in 25mm or 10mm eyepiece. It is a blue star, and i
can see a total of 22 stars in my FOV under 25mm eyepiece. The 22 stars seem
fairly evenly spaced throughout the eyepiece. I note a nice halo of light that
surrounds Epsilon Ori plus the star holds magnification particularly well.
But no luck with splitting the star.
