Messier 1012 views2006-05-16 22:49:00 M10 NULL 9x63 Meade Travelview Binoculars 5.8° field of view 9 Could see stars down to Lambda (mag. 4.40) in Serpens Caput with the naked eye. Starfield was fairly sparse (especially as compared to the nearby Serpens Caput's head). I centered the field of view on three close dim stars in a right-triangle shape. I found the field of view by pointing the binoculars at the naked-eye star Han (Mag. 2.53) and moving to the left two fields to find two bright binocular stars (at the bottom of the drawing below) 23 and 30 Ophiuchi (mag. 5.21 and 4.81). M10 was found above 30, a little to the right, to from a 5-12-13 right triangle with 23 and 30. Globular was diffuse and dim, no visible nucleus. The two bright stars at the very top are close to M12 (not drawn, just outside field of view) which looks about the same as M10 in binoculars. At 22:57, a meteor passed through the field of view (drawn). It took about one second, much faster than an airplane or low-earth-orbit satellite. It brightened twice (both times to magnitude around 4, from magnitude about 6) as it passed through. There was no visible trail. It was white. After I finished drawing the field of view, I scanned somewhat randomly with binoculars and caught another meteor in nearby Corona Borealis at 23:08, moving roughly the same direction, passing through the field of view in less than a second, and brightening once, leaving a faint and very short lived trail one degree behind it. These might be Epsilon Aquilids.
