Easy double, however I use medium - high power to darken the sky. It is rather wide. The primary star is bright and has a beautiful yellow color. The secondary is very more dim but it is still visible with direct vision, its color is obscure. The rings of the primary are too much in movement to be well visible. Estimated PA about 100 degrees. Beautiful color of the primary, otherwise this star is not very interesting. | |||

Faint companion in the 26mm Ploessel at an estimated PA from 90°. 2049: Not a clear split. "Bump" in 180° in the 8mm RKE (250x)° |

11:40pm
PDT 12mm ortho (40x)
and 6mm ortho (80x) I thought I saw a hint of the companion at 40x but
really
couldn't resolve anything until I increased the power. At 80x I could
get a
clean separation though it was still very close. The companion was
obvious with
direct vision. Very nice.

| Star: Struve 2110 Date: 2006 July 26 Time: 21:00-24:00 UT Seeing: 5 <1-10 Seeing Scale (10 best)> Transparency: clear Location of site: Vienna, Austria Site classification: Suburban Conditions: Moon: Sky darkness: 4.5 <Limiting magnitude> Telescope: 130/1040mm refractor Camera: SBIG ST237A CCD Exposures: 6 or 12 x 10 seconds for astrometry. Distance/PA measurement was done with these images also except where noted (bright stars need shorter exposure times of 1 sec or less) Image measurement: astrometry with Astrometrica software and UCAC2 or USNO B1.0 catalog (see http://www.astrometrica.at); with exact focal length and image orientation I measured distance and PA with AIP4WIN software. I took means of measuring all my images for a star. There is a scatter of 0.2 arcsec in separation and 0.2 deg in PA. Scatter in PA is much larger if the stars are very close. Note: All images have north up Eyepieces: n/a Magnification: n/a |
