Vega - challenging double?

[Stu]

If it helps, this is from SkySafari at x53 with a 1.88 degree fov down to mag 11 and flipped vertically to match newt view (I think!)

I'm struggling to match the star field or identify the double!!

This is with a circle at 0.022 degrees which if my maths is right is 1.3 arc minutes or 80.2 arc seconds??? No star showing even down to mag 18!

Confused

I get an eyepiece view very similar to Shane's - I've even broken the habits of a lifetime and done a sketch myself!

I can't match it against Stellarium though, but I am sure that the star immediately next to Vega in Shane's sketch is the one I take to be secondary - it's certainly about the right sep and PA.

What's the fov of your sketch Shane?

it's a 15mm plossl in my 6" f5 newt so 50x and therefore 1 degree field.

I'll have a look next time out and check I was not seeing things.

I don't really fo software or goto, just find the star and look/sketch!

This is looking more like it, 15mm Plossl in an f5 6" showing down to mag 11. It is flipped in both axes to match you sketch Shane. It's pretty close, and by the fact that there is no star where you have shown the double it looks like you are right? I guess SkySafari doesn't show it?

cheers Stu

I am quite impressed for a sketch that took about 2 minutes to do!

[Moonshane]

ps I'd repeat my earlier comment that it was much more obvious at 50x than 100x.

This is my (grotty) sketch showing about 28 arc min vertically. My art teacher said I had the artistic skills of a carrot! I still can't see the star listed at due E of Vega, mag 9.5 though. odd/suspicious.

Never new Vega was a double.  I shall look closely when it clears.

It's quite a system.

You might need the FLO Clearance Hubble though for most of these.....

I'm surprised it hasn't sold yet ;-)

Where is Joves, he'll have it :-)

The SW120ED pulled out this star, which surprised me,used 13mmfl for about 69x.Extremely low scatter with this scope,diagonal and eyepiece combination.
