This is a negative report:
although it was easy to locate this, I was unable to
even get an elongation on this.

Date & Time: 27 December 2003 19:00 to 22:00 (UT -5) Seeing: 7 to 8 <Pickering> Transparency: <1-10 Scale (10 best)> Location of site: Catawba, VA U.S.A 37° 16' N 79º 57' W Site classification: Rural Conditions: 0% cloud cover, excellent transparency, light surface breeze Sky darkness: 4.0 <Limiting magnitude> ( 1st 1/4 moon) Telescope: TV NP101 f/5.4 APO Refractor Mount: TV Gibraltar Eyepieces: Nagler type 6 (11, 5, 3.5, & 2.5mm) Panoptic 24 used as finder Magnification: 216x |
I had tried on 2 previous
occasions to split this double; both times failed due to poor seeing. On
this night the steady sky cooperated and success was relatively easy. Once
located with the 24 Pan I switched to the 2.5 Nagler (216x). The elusive
B star began to pop into view with direct vision. Averted vision revealed
it very easily. During brief times of unsteady seeing B was obscured in
the diffraction ring "noise" from A. But most of the time it was a clean
split. I could not appreciate any real color indications. A appeared white,
or "ash" colored. While B seemed to be something other than white I could
not assign any particular color. Maybe it was simply
the broad difference in magnitude that gave the illusion of color. This was a tough one, at least for me. It was quite satisfying to bag it.
