Hi Trevor
By sheer coincidence, I managed to split Alnitak on 15th January and this leads me to believe that although you have produced a terrific image, I don’t think that you may have “split” Alnitak?
What put me onto it is that I had to use an x4 PowerMate on my 180mm F12 ‘scope, giving me an effective focal length of 8640mm! The separation is around 2.23 arcsecs.
Having a quick look at The Sky, I think a better candidate for your close companion is GSC4771:1207 which is around 58” away?
What do you reckon?
Cheers
Dennis
