Beautiful Uranus

On Octobre 30 I finally had a chance to observe Uranus. The sketch is made using the 12 inch Dobson from Orion Optics mounted on an Equatorial Platform. I used a 12mm Nagler. The magnification is 133x and the FOV is 37'. The observation and sketch were made from my backyard, between 22:00 and 23:00 local time. The seeing was somehow stable, but the transparency was bad. With the 2x powermate installed I could barely see a hint of green-blue color on the planets disk. there were no details visible. However, it was a very pleasing observation. Uranus really stood out as a little disk from its starry surroundings.

Sketching Mars
On the night of December 11 I observed Mars from 20.30 UT until 22.00 UT. I use the 300mm Orion Optics UK on a dobsonian mount. The eyepieces used were the 12mm Nagler and the 7mm Pentax. The seeing was not to good, so I was limited to medium magnifications. Still every now and again there were some fine details visible on the surface of mars. The sketch below should is just a rough impression from what I saw that night. You can see I identified a dark area looking like a large bird. The body of the bird (central part) is Syrtis Major. The wings are Mare Tyrrehnum and Mare Serpentis. I also detected the North Pole and a dark area right above the North Pole, probably Utopia.


It was made with the using the 7mm Pentax XW, giving a magnification of 229x. Of course Mars didn’t look as big as the circle on the paper, but I like to sketch objects on a larger scale. Some of the techniques used for sketching Mars come from the book “Astronomical Sketching” from the Patrick Moore Practical Astronomy Series, a book which I can highly recommend.

The Moon, Venus and Jupiter steeling the show this morning!

This morning, about 05.30 UT I got up for work. I looked out of the window, and there I saw a great line-up of three of the brightest objects in our night sky, the Moon, Jupiter and Venus. What a way to begin your day as an amateur astronomer! The images below all

Some digital images of Venus

On May 18th and 19th I took some images of Venus in the western evening sky. Venus is still very bright with a magnitude of -4.0. Through my big binoculars it looked like a small crescent moon. At the moment about 1/10 of the surface is lit by the Sun. Looking through the telescope I realized how big the diameter is at the moment (49.1"). Here are some images I took during .......follow this link to read the full report

Four Jupiter moons lined up

Tonight I observed Jupiter.  The 4 big Moons all could be seen on one side of Jupiter. Even at low magnification I could detect see Jupiter divided into 7 different zones and bands.......follow this link to read the full story
