Aitken 58
Date & Time: 5 Jan 2003 8pm to 12:30 pm local Seeing: 4 <1-10 Seeing Scale (10 best)>. Transparency: good Location of site: Silverdale WA, USA 47N 123W Site classification: suburb-rural Conditions: 35F, some dew Sky darkness: 5.7 <Limiting magnitude> Telescope: 17.5 in Dobson with goto mount Eyepieces: not used Additional: PC164C video camera Magnification: 350x video at pf with paracorr |
A
close almost joined pair at this magnification. Really needed to throw
on the 2x to get a good measure, but to cold outside to go out and the
air too poor to support more magnification. There is also a C component
along the same position angle. The WDS lists no magnitude for this companion,
cataloged as GIR 1, but I guess it is about 12.
Measurements: AB, somewhat poor, 5.60 sec at 158.7 sec, AC 95.25 sec at
155.7 deg PA.

This was pretty
faint, but still easy to find and split. There is a slight, but noticable
difference in magnitude. I couldn’t tell much about color.
First attempt at finding this revealed almost nothing: stars of any kind. Then it dawned on me: Dew! A trip inside to procure a dewzapper (aka my wife’s hairdryer). After zapping the dew, it was fairly easy. Again there was a fair amount of magnitude contrast, but it was still easy to split at low power. The primary was tinged with blue, but the secondary was too faint to tell. |
