Hi,

I got up early to observe Jupiter and Mars in the morning sky. It was clear and cool. The Harvest Moon was bright in the western sky, while bright Jupiter in Gemini changed the outline of the constellation. Ursa Major was low in the northern sky, and Cassiopeia was high overhead. In the southern sky Orion and Sirius were bright. It was nice to see some old friends again.

One of the things that I enjoy about observing sessions is listening to the sounds of nature. For example down near a river I could hear some geese as they honked a few times before settling down in the cool night air, and later heard a small animal who was foraging for a snack near some trees. I listened also to overripe fruit falling to the ground from some other trees.

I set up the TMB 105mm (4.1") f/6.2 on its alt-az mount and took a quick look at M42 using a low power eyepiece. Even with the bright moonlight I could see some of the nebulosity in the Orion Nebula.

I then inserted the Baader binocular viewer with the 1.7x corrector, with a Baader Planetarium Moon & Skyglow filter, and TMB Monocentric eyepieces and began observing Jupiter. The seeing was variable, sometimes fair, and other times good. Magnifications varied from 123x - 185x.

Some of the detail that I noted included the South Polar Region, which appeared brown in color, and the South Tropical Zone appeared white in color. The South Equatorial Belt (SEB) was reddish brown in color.

The Equatorial Zone was white in color.

The North Equatorial Belt (NEB) was reddish brown in color, although it appeared to be more reddish brown in color than the SEB did. However, the SEB appeared wider than the NEB. Also there appeared to be rifts in the NEB.

The North Tropical Zone appeared white in color, while the South Polar Region which appeared gray in color.

Here is a link to my Jupiter Nomenclature page:

After I finished observing Jupiter I noted that Mars was above the trees. Its orange color reminded me of Betelgeuse in Orion. Through the telescope the seeing was not as good as it was for Jupiter. Still I was able to make out it's gibbous shape and it was nice to observe it again.

Also as Mars is near Comet C/2012 S1 ISON in the sky I will be able to use Mars it to locate the comet once the Moon is near its new phase:

Eric a very nice report. I envy the TMB you've got . I haven't made it out early like some if you guys have - can't wait for Jupiter but particularly Mars.

Eric, thanks for including a link to the great chart for finding ISON. Since I wake up early anyway and prefer to have my coffee under the stars, I'm going to give ISON a go.

Hi Ed,

Thanks, and glad to hear you find the ISON chart helpful.

Having coffee under the stars sounds like a nice way to start the day :jump:

Best,

Eric
