Mizar-A, Mizar-B, Alcor....

Recommended Posts

The first image Mizar-A and Alcor, Mizar has a double refraction, this turned out to caused by Mizar-B not seen this mentioned in forum threads so the second image is a 1100D hanging on the end of a Pentax XW 5mm via the 43mm Adapter ring....

I really like that first photo - I think you can just see a 'bump' on Mizar A (at 10 o'clock) which I presume to be Mizar B?

If that's the case why is B at 4 o'clock on the second photo?

I must be misinterpreting the photos but how?

Now that is interesting, there were taken 2 days apart but i doubt that's the reason, i set Stellarium up for the first image date and its about how it would be, so i can only think i reversed the image in photoshop so its how our eyes would see it and not how the camara would image it, the 2nd image Mizar-A & B i didn't i think that's how the camera took the image and that's how its displayed, something to get right in the future i'm thinking, thanks for the input....

Nice pictures.

The Mizar/Alcor system was the first thing I ever looked at through a scope, and I still regularly enjoy looking at it.

I managed to split them in my binos just recently, and they fabulous in any scope.

Like the piccies.

For an easy double with no colour difference it seems strange that so many of us, me included, have a great affection for this system.

For me it has interest when viewed naked eye as a double, through binos where I can just about split Mizar, and then at higher power through a scope where it is an easy split. The fact that all three are apparently spectroscopic doubles aswell make it a wonderful six star system that is always on show.

Very simple but it always has been something I love looking at every time I observe.

This was my first double a few years back when I got my first scope. It was one of the few stars I could actually identify. It was also one of the few that I could get a good view of from my back garden. Unfortunately, light pollution from my back garden streetlight ruined my viewing and I sort of lost interest and sold the scope. Sigh !!

Shame Allcart. Are you getting back into it now? Maybe a pair of binos to get going again?

Sounds very sensible. You can see loads with binos, can take them anywhere, and will find your way around the sky.

Have fun.

Aha! Now I know what the double actually means! I didn't realise they were THAT close together. When it was suggested to me the other day to look for them in the plough handle, I looked through at Mizar and then saw another star near to it and thought that was what it was.

But now I know I was wrong and that they are incredibly close.

Thank you for sharing.
