Otto Struve 525 in Lyra new
      #2557156 - 08/03/08 03:28 AM

Howdy all;

Have a look at Otto Struve 525 at 18 54.8 +34.0. It is a colorful 6 and 7.5 mag pair that is near the Ring Nebula. In my 6" f/8 refractor with a 27mm eyepiece it would split this pair, show the colors as medium yellow and light blue with good color contrast...and...show the Ring Nebula in the same field. Pretty cool.

Enjoy;
Steve Coe

Steve

My view on Otto Struve 525, in my 4" refractor, was quite simile. You might want to take a look at Struve 2421 in the same FOV as 525.

Did you try for the B component? With my 8" reflector, I saw this triple same as Webb recorded - yellow, no color, blue.

neat trick to do with otto struve 525 is to observe it and then observe nearby albireo and notice that there isnt much difference, try and notice the minute differences like the placement of the stars.

Hi Steve. I think the star you refer to is SHJ282, which is an easy coloured pair at 15x in a 90mm scope. Otto Struve 525 is the closer A component (6.14, 9.12 1.8" P.A. 128 degrees). Do as VanJan has suggested and try and split the AB pair.

This is a beautiful field on a dark night at low power - Beta Lyrae, the Ring and this star all fit nicely in a 2 degree field.

Why can't these people get this naming convension easier to deal with? What a pain.

So, the wide pair is 282 by South and John Herschel and the close pair is the STT 525 pair? Is that right?

I think of all the articles I have written over the years and used the wide pair as STT 525 and no one has ever corrected that error. I think I got it from Burnham's, maybe.

Crazy, man, crazy;

Close pair = STT 525; A and B components. Wide pair = STT 525; A and C components. A and C alternately known as S,h 282. Double star nomenclature can be confusing at times, but there is a logic to it. One gets used to it after a while, and the multiple source checking of names and component designation. I am reminded of Agnes M. Clerke's famous quote, "... it has come to pass that a star has often as many aliases as an accomplished swindler."

VanJan;

Thanks, I will make certain that the SAC double star database will read AC for this pair, I have never tried the close pair I may need to put that on my observing list.

Thanks;
Steve Coe

Main component nicely split tonight at 250x with 6" refractor. Yellow and bluish. Seeing was good to moderate. No moon.

Thanks guys, never knew there is a B component. Now I gotta look for it.
