Don You have to come back, we now operate from a site at 10,000 ft on Haleakala. Seeing is excellent to spectacular. Thanks again for your help. Aloha Rob Sent from Rob's iPad

Hi Siegfried,
From Hawaii, Mizar is quite far north and I don't think it is as commonly viewed as it is here. Objects like Alpha Centauri, Omega Centauri, the Southern Cross etc. which Rob so kindly showed me when I was there are much more commonly viewed.
Clear Skies,
Don

You mean after all this, the star was the normal companion star to Mizar? The companion about the same brightness as Alcor?

Hi Don
I have the Plus version so I think having the missing B companion set me loose. We did check on a Pro version but didn't expand the field. It is a curious thing as to why such a bright and important star is not shown on the Plus version. Thanks for helping me solve this mystery and showing a small problem in the app.

Hi Rob,
My version of SkySafari Pro shows the companion if you continue to enlarge the image but not initially. See http://www.skyandtelescope.com/observing/m http://www.skyandtelescope.com/observing/mizar-a-fresh-look-at-an-old- friend03252015/ izar-a-fresh-look-at-an-old-friend03252015/ for an eyepiece view at 45x close to your binos. I think the problem arose because you had a data source that showed a .5" separation instead of the correct 14".
Clear Skies,
Don

Hi Don
The image at One Minute Astronomer is what I see though it is not shown on my SkySafari app. Then I guess I was seeing Mizar B in the binos and C9.25. Patrick did a set of exposures at .01, .1, .5 and 1 sec, nothing was seen. If you see it in you binos, then the mystery is solved. Thanks!! but it does make me wonder why it's not shown on my app.

Hi Rob,
The .5" companion does not exist as far as I can determine. The 14" companion is visible easily at 20x in a 60 mm spotting scope. Patrick's image was just overexposed so you didn't see the two stars. Check out this image http://oneminuteastronomer.com/8187/mizar-polaris/ scroll down you can easily see Mizar A and B and Alcor.
Clear Skies,
Don

Hi Don
I have Mizar's companion being listed at .5" separation @ 218* and mag 3.9. Where did you find Mizar A and B?? But then at 14" I should as well as Patrick be able to see it. I have Uranometria 2000 and SkySafari on my iPad plus access to many other charts on line. I did find info about the Mizar system at Domeof the sky.com that states the 14" separation for the B component. Friday I knew that what I was seeing was not the companion even if it was at 14" separation, the binos cannot resolve that close of a pair, but we saw something.

Hi Rob,
I am not talking about Alcor. Mizar A and B not Alcor are separated by 14".

Hi Don
I easily see Mizar and its visual companion Alcor easily. I also see the SAO that forms a triangle, what I am seeing is CLOSE to Mizar. If I were just starting out in astronomy I would be making mistakes, but 20 active years plus an interest back to when I was 12 makes me know what I'm seeing and having 2 others see the same object confirms that it's not an illusion. If the weather clears I'll get an image Thursday night and post it. The BT100 binos are mounted on a HD tripod and in July I will have the Losmandy AZ8 mount for them.
Looking up, Aloha Rob

Hi Rob,
I can see the companion to Mizar in my 15 x 50mm image stabilized binoculars. It is not .5" but 14" of separation. Maybe you saw them split. They are easy at 20 x. When referring to distance of separation between SAO 28748 I should have clarified that it was one minute of RA. Dawes limit for a 100 mm scope is 4.56/4 = 1.14". Even at low power splitting Mizar should be easy.
Clear Skies,
Don

Hi Don
I know that star and that is not it. What I am seeing is close to Mizar, about 1’ and SSE. Sao 28748 is 8’16” from Mizar. Friday at the STEM Conference in Wailea I saw the triangle but close to Mizar was this other star and I didn’t remember it being there. The companion to Mizar is at .5” and shouldn’t be seen in BT 100 binos. I saw the star again last night in the binos and in the C9.25 under different magnifications. This is a very odd thing, I appreciate the help in trying to solve this oddity.
Aloha Rob

Since the handle of the Big Dipper rotates the cardinal directions of the star with respect to Mizar also rotates.
