    There were about 10 observers at Montebello tonight (2/22/03).
    The seeing was quite good we had high thin clouds move over, but
    most seemed to be to the east of us. There was some dewing but not
    too bad. As I was leaving about 12:30am the dew had cleared and the
    skies were more transparent. I got to MB about 6:45pm.

    I was using my 6" refractor. Early, it was easy to see six stars in the
    Trapezium. The small companion star to the eastern belt star in
    Orion was easy to see. Saturn was showing very nice detail. A little before
    Sirius
    transited I tried to see if I could find "the Pup". Another observer there
    had suggested trying to see it. We both looked. We did see a much
    less bright spot at about 4:00 o'clock, near the outside edge of the
    series of defraction rings. I was using a 90 deg star diagonal with
    a binoviewer stuck in the diagonal like a large eyepiece. The binoviewer
    was pointing up. If I remember correctly we were using close to 300x.

    In the early evening Jupiter was showing thin curved lines in the EZ.
    By about 9:45 pm the GRS was in full view. there was much more
    detail. White ovals were following the GRS. I should have made
    notes and made sketches.

    About 11pm I looked at M3 and M51. They weren't anything to write
    home about in my 6". They looked much better in another observer's
    11" SCT. The last object I tried was the close double star Porrima.
    It was a little low for best observing but it was split. You could see two
    not so nice Airy discs almost touching.

    Equipment:

    AP 155EDFS 155mm f/7 triplet APO refractor
    Zeiss binoviewer and AP barlow element used
    directly in an AP Maxbright star diagonal.
    Zeiss Abbe Ortho eyepieces (10mm used to
    view The Pup. The binoviewer has a 1.25x corrector.

    Other eyepieces used, Pentax SMC-XLs used in
    mono mode with the Maxbright diagonal.
