Date & Time: May 08 2001 Seeing: 4 <1-10 Seeing Scale (10 best)>. Location of site: Annen, The Netherlands (53ºN, 6ºE) Site classification: Village backyard Sky darkness: 4.5 (UMI) <Limiting magnitude> Sky : Good transparency, bad seeing Telescope: Celestron C11 (11" f/10 SCT) Magnification: 140x, 280x Harschaw's Scale: 3 <1 to 5> |
A rather close double which needed 280x for good separation. At 140x only elongation was seen. A nice pair with pretty colors : Bright-yellow and deep-yellow, but a bit too close for a good rating. The not far off 39 Bootis is very similar but only with greater distance : colors the same and magnitudes almost the same. | |||

a sep. of 2.2? PA 53 AD 2000, and you
get confirmed looking at the eyepiece.

Location of site: Posadas (Córdoba), Spain 37º 48' N - 5º 08' 30" W 100 mts over sea level Site classification: Suburban Sky darkness: 5.5 <Limiting magnitude> Temperature: 24ºC Telescope: Helios 120 mm f/8.3 achromatic refractor Eyepieces: Plossl 10 mm, Plossl 7,5 mm, Microguide 12.5 mm, 2x Barlow, diagonal prism Magnification: 133x, 263x, 500x |
Using Plossl 7.5mm at 133x
I couldn´t decide if I had split the two or not. Really, in my opinion,
it seemed to be a peculiar star. At 263x a beautiful pair of deep yellow
stars was observed. Using the MicroGuide at 263x and 500x I obtained some
measurements which from an average of 5 measures at each magnification
gave a PA of 55º with a separation of 2"12 sec.
