--Boundary_(ID_6DRg25raZt2CI/JgckV07g) Content-type: text/plain; charset=US-ASCII; delsp=yes; format=flowed Content-transfer-encoding: 7BIT I had a very successful morning (May 27) focused on Jupiter and Neptune. The sky was mostly clear (a slight haze) but quite suitable for my early morning observation of Jupiter and Neptune. Certainly the best period for viewing was the half hour straddling 4 a.m. I truly felt a connection with Galileo, as I studied the eyepiece star field, trying to evaluate the distances between objects in terms of Jupiter-half-diameters as Galileo had done for his diagrams of Jupiter with its moons. or < http://articles.adsabs.harvard.edu//full/1997BaltA...6...97S/ 0000099.000.html > I recorded my observations at the telescope in a diagram based on Jupiter-half-diameters units (perhaps I'll have a chance to share the result later). My main observations were made between 03:50, and 04:25 , but made a last one at 04:40, just before I put the scope away. I made the view through my 10X50 binoculars my first observation. I found the binocular view a big challenge. The contrast of Jupiter's brightness made it really difficult to single out Neptune's dim light only a fraction of a degree away. I really had to have the binoculars well focused and steady to keep Neptune in view. I had to find ways to diminish Jupiter's light by putting just out of the field o view to get a stronger image of Neptune, ....but see it, I did: Jupiter below, Neptune, a faint little point above-left , and the brighter star in the field, mu Capricorni above-right. Two planets and a star in the same view. I would judge that some observers would have had some difficulty deciding whether or not they could see Neptune. If I had not known what I was looking for and what to expect I would have been in doubt. The view in my telescope was a different story. I used 46X and 92X with my 254mm Coulter (a 10 inch diameter reflecting telescope). The view of Neptune, Jupiter and Mu Capricorni were easily framed in the view (at those powers, Neptune's disk eluded me, Roy Bishop reported being able to see Neptune's disk at ). Jupiter's disk and its 4 Galilean moons was a great sight (two moons were arranged on each side of the planet. By 04:20 I had an initial sketch of the view made. At 4:25 I could still see Neptune steadily, but certainly the dawn was beginning to overwhelm the view of fainter points. In my final look, just before 04:40, It was difficult to see Neptune's point of light; I could hold it in view only momentarily. Toward the end of my observations I was aware of the growing dawn chorus of birds. About 4:30 a robin started its melody, to be joined by other robins and 2 or 3 Verry thrushes, along with song sparrows, an Oven Bird and crowing pheasants. I also attempted a peek at Venus and Mars; Venus was there (low east) but Mars was covered in hazy, low cloud. I forgot about looking for Uranus until it was too late. I didn't hear the owl Roy spoke of. but i did hear the beat of waves washing in on the beach below (the full tide would have just started to ebb (high at 03:30)). The whole experience made for a wonderful early morning. Dare I say that it felt like Galileo and I had just spent some time together?
