Equipment: Sky-Watcher Explorer 130M

No Moon. Very breezy and very cool night.


Time: 2005-05-07 21:31 UT

Worked up from 25mm to 10mm with 2x. With 10mm + 2x Saturn was almost swimming around, the atmosphere seems very unsteady. Could just about make out the shadow on the rings but not much else was visible.

Went star-hopping for M97 using the 25mm eyepiece. After not too much effort managed to find it. Made a rough sketch of its location to relation to surrounding stars so I could double-check with charts later on (that check confirmed that I'd managed to get M97).

With the 25mm eyepiece it was an obvious if faint circular "smudge". No trouble seeing it with direct vision.

Tried next with the 10mm eyepiece. I could only see it with averted vision. There were moments when I wasn't sure I was actually looking at anything at all and then it'd sort of fade into view again. Noted that I could see a very faint star very close to it.

At 22:32 I switched back to the 25mm eyepiece for a wider view and in the following three minutes saw a satellite and then a meteor pass through the field.


Time: 2005-05-07 22:39 UT

With the 25mm eyepiece all four moons were visible. Jupiter itself was almost too bright to look at. Noted that I was getting four "spikes" off the planet (presumably from the legs of the spider holding the secondary mirror).

The two main belts were only just visible, the brightness of the planet appeared to be making it very hard to see any detail at all. As noted in another log: I should probably think about looking into some filters.

Made a sketch of the position of the four main moons.
