Look out!  There is an imposter nearby!  This would be 6.4 mag SAO 102571, an A star with a faint companion of about the right magnitude and separation (but wrong PA) as Bur 822.  The imposter lies 12 minutes NW of Bur 822. 

But 822 shows a Yellow and White pair.  Not much to write about.

Seeing: 7 to 8 (1 - 10, 10 best) 
Transparency: 6 to 7

After 5 measurements with the MicroGuide I arrived at a mean separation of 
108.6 arc secs and a mean PA of 132.5º which compares favorably with the the Sky Catalog 2000 listing of 108.1 arc secs and a PA of 134ª. 

The first listing of the WDS is 108.1 and PA of 134º. However it is far from the last WDS listing of 117.8 arc secs and PA of 197º  which I find suspect. 

My results agree with the Burham listing and the Sky Catalog 2000 listing. However the WDS listing gives a first result of 108.1 arc secs and PA of 134º and a last result of 117,8 arc secs and PA of 197º. This last result of the WDS seems to be in error to me. Does anyone have the Tycho results? 
 
 

Separation (Clear or Touching):AB Clear and AC Clear 
Magnitude Comment: A = 6.4, B = 11 and C = 10.9 
Color Comment: A = Bluish White, B and C are both white and dim 

I made five measurements of the AC components and arrived at a mean of 114.6 arc secs for the distance and a mean PA of 196.6º. When I was making the measurements I had an idea of the PA at being about 190º thereabouts but the distance I didn't remember. Last night when I finished I compared my results to the WDS last results and noted that the distance was less by about 3 arc secs which I thought was close and the PA was right on. This morning I looked up the results that Francisco had sent me and I was very happy to see that my results were almost exactly the same as the latest figures of Hipparcos and Fonac. My linear constant of 3.95 arc secs per division helps very much in the linear measurement and Tom's drift method for determining the PA is fantastic.

I split the AB components with a 5mm ortho at 400X. I bought a Vixen 7mm ortho and a University 5mm ortho some years ago for planetary work but the magnification was too much and I only used these eyepieces once in a while to collimate the 8" SCT. They mostly were unused until I began to split double stars. Now I see that these two orthos are worth their weight in gold in this part of amatuer astronomy.
