Observing Log for Mike Durkin
4/24/2004 from about 3 PM until midnight
Oyster Bay
Transparency: 7/10, Seeing: 5/10
Celestron Ultima C8 PEC
Started observing the sun using the solar filter for the Celestron C8. I was a little disappointed
that the seeing seemed very bad. There were 2 sunspot areas that I was able to see. Despite the
bad seeing I think I shuold have taken a couple of pictures.
After that I used the setting circles to find Venus and Juptier during the evening. I would first
center on the moon, set the circles for the right coordinates, and then move to the coorindates for
Venus and Jupiter. I was able to find both planets.
M101: I tried to find it, an even though I know I was in the right area. I guess I need darker skies
in order to be able to see it.
M53: I found this when I was just randomly aiming my scope around the Virgo area. Observerd at
30mm(67x). At first I thought it was a galaxy rather than a globular cluster since I was unable to
resolve any individual stars.
M57: Finished off the night by taking a look at the Ring Nebula.

Oyster Bay, about 50 degrees

Celestron Ultima C8 PEC
Seemed to be a very hazy night and although no significant cloud cover, I could not make out the dimmer stars.
Started with Venus. Seemed about 40% illuminated, although being low on the horizon there was a lot of
chromatic abberation. I took some pictures with the digital camera including a blue filter to try to reduce the
abberations.
Next went on to Jupiter, which was very close to the zenith. Looked very impressive and I think the seeing was
excellent for the night. teh south polar region had shading that semmed to extend almost all the way to the equitorial
belts. The southern equitorial belt also seemed to be split slightly. The northern equitorial belt was more irregular
in appearnce and seemed to have knots in it. The northern polar region seemed normal. Originally I thought I saw a
shadow from one or two of the moons, but according to Sky and Telescope's almanac, I missed it by a couple of hours.
Also according to Sky and Telescopre, the Great Red Spot should have transited 1-2 hours before I was observing, however
I don't recall seeing anything like that. I did take some astrophotos, which I need to process and examine. Perhaps I
will see if the GRS is there. Viewing Jupiter in the monitor of the camera was very impressive, despite the noisy
quality.
Finished with a quick look at Saturn, which was somewhat low in the west. It is definitly smaller in size than when I
viewed it in recent months. I did see some turbulence in the air, although it was much slower than the turbulence I
normally see when observing. Did see the Casini division, but couldn't make out any fine details.

Oyster Bay, about 45 degrees
Transparency: 5/10, Seeing: ??/10
10x50 binoculars
Decided to try to observe Venus and Jupiter with the binoculars. I was haping to be able to make out the phase of
Venus, but either the astigmatism in my eyes was causing problems or the optics in the binoculars isn't good
enough.
While observing venus, I just happened to find M45, or the Pleiades. Observedabout 15 stars in the cluster, with
the brightest stars forming a dipper or cup shaped pattern. The cluster covered about 30-50% my field of view
(1.5-2.5 degress).
Also took a quick look at Jupiter. No significant details observed.
