Struve 306
Date & Time: July 12-13, 2003 Seeing: 3 [see http://www.backyard-astro.com/Logs/logsreport.html Transparency: --- Location of site: 45°N // Tomahawk WI, USA Site classification: Rural Temperature: 56°F at 10pm CDT, dropping to 50°F by 3:15am CDT Sky darkness: 10/10 (Thompson Scale) Conditions: Not too much dew; extreme Lunar interference; generally pleasant Telescope: Meade 8" f/10 LX-10 (Snoopy ) Eyepieces: 32mm, 13.8mm, 9mm, 5mm Magnification: 63x, 147x, 226x, 406x |
Located inside open cluster
OCL 368.
I'm never quite sure which is 'B' and which is 'C' when there are two companions involved, but the following is the best I can do. 'A' appeared to have a bluish-green
tint.
Picture an elongated triangle
balancing on it's tip, and then falling to the right. The star which is
now 'up' is the 'A' star, having the 2.2" sep. star nearby. The other star
which was at the top of the triangle but is now lying on the 'ground' is
the 124" sep. star, and has two other very dim [in this moonglow, anyway]
stars curving towards the 'A' star. Very pretty arrangement.

Date: 29, July, 2003 , 23:45 -> 2:45 local time Location of Site: Sena de Luna, Spain 42.55N, 05.57W Seeing: 8->7 <1-10 Seeing scale (10 best)> Transparency: 8->7 <1-10 scale (10 best)> Other conditions: No Moon. Temperature:18ºC Altitude: 1,200 mts (3,940 ft) Site classification: Rural Sky darkness: about 5.5 Telescope: Takahashi FS-102 Mount: Vixen GP + Skysensor 2000 Eyepieces: 9mm Nagler, 5mm and 3.8mm Eudiascopics Diagonal: Zeiss prism diagonal Magnifications: 91x, 164x, 215x |
Using the 5mm Eudiascopic,
the open components are no problem. The AB pair, tighter, is observed as
a clear split intermittently, since transparency seems to be deteriorating.
Moreover, the small altitude over the horizon of this system at this time
of observation doesn't help.
