Struve1547 (Multiple Star, in Leo)
Observer: John Callender (e-mail: jbc@west.net, web: http://www.west.net/~jbc/)
Instrument: 8-inch Dobsonian reflector Location: Carpinteria, CA, USA
Light pollution: light Transparency: fair Seeing: fair
Time: Wed Mar 12 05:30:00 1997 UT Obs. no.: 102
Neat color contrast; the yellow-white primary and a much fainter, brownish secondary. Easily split at 49x, and that power gave the most pleasing view; at 122x the secondary faded to a dull gray. I estimated the PA at 345 degrees. According to dObjects, PA is actually 326, separation 15.4 seconds, mags. 6.1 and 8.2. Per Burnham's, spectral classes are dF7, dK6. This star is actually 88 Leonis; I need to fiddle with the AAOL object database to allow using that designation.
