Date & Time: 6 July, 2001, 03:00 to 04:55, UT Seeing: 8 <1-10 Seeing Scale (10 best)>. Transparency: 6-7/10 ,variable, due to high hazy clouds Location of site: Northern Kansas City, Missouri. 39º 15' N, 94º 30' W, 980 ft above Mean Sea Level Site classification: Suburban Sky darkness: <Limiting magnitude> Telescope: Celestron C-11 Eyepieces: 25mm Plossl, 9mm Lanthanum Magnification: 112x, 311x |
Position: 1859+2936
Magnitudes: 9.07 (G0), 9.18 Sep/PA's: 1.6- / 6+ Year of this measurement: 1999 Colors noted: W, O? Comments: Observed
at 112x, where duplicity was suspected due to a peanut shape of the star.
At 311x, the split was wonderful and easily held. This is a strange
contrast to Hussey 936, which is theoretically a little wider, of nearly
the same magnitude, but much more difficult to split.

Location of site: Killeen, TX, USA Site classification: Suburban Sky darkness: 4 <Limiting magnitude> Temperature: In the 80's F (30's C). Slight breeze. Telescope: Celestar 8" SCT Eyepieces: 25mm, 17mm, 10mm Magnification: 80x, 120x, 200x |
A very tight pair. I got
elongation buy I cannot claim a clean split, even at high power.
Occasionally I thought maybe I had it at high power, but I was really not
sure.

At 93x a very tiny but well
separated double. The star-images were small and sharp, which made the
separation clearly visible. The pair sits in a beautiful rich field (as
most of the Lyra doubles...). There is a striking asterism along the NE-edge
of the field (at 93x), a long string of mag. 10 to 11.5 stars with the
two brightest stars at the top, orientated at a right angle to the string.
It looks like a winding serpent with two fiery eyes.
Both stars are white |

Here 165x paid off giving
me a N/S elongation, but 225x did not do the job (I got this one on the
second run)

Tackled and resolved fully
this time, at 225x.
