Location: Billingborough (South Lincolnshire, UK)
From: 2005-04-16 20:20 UT
To: 2005-04-16 21:15 UT
Equipment: Sky-Watcher Explorer 130M

After a couple of quick sessions with the 130M in the week or so prior this was my first "proper" observing session with the new scope (as in, I took the time to keep notes).

First quarter moon.

Atmosphere rather unsteady. Dew kept forming on everything and the eyepieces kept misting up whenever I went near them.


Time: 2005-04-16 20:20 UT

Viewed with 10mm eyepiece.

Both of the main bands were visible but rather faint. In moments of steady seeing the bands seemed to take on a faint "mottled" appearance.

Io, Callisto, Europa and Ganymede all visible.


Time: 2005-04-16 20:54 UT

Viewed with 10mm eyepiece plus 2x Barlow.

Very obvious seperation between the rings and the planet. Saw a faint hint of the shadow of the rings on the planet and there was an obvious shadow of the planet on the rings. No obvious detail on the planet or in the rings although, in moments of very steady seeing (very rare), I thought I could see a hint of the Cassini Division (although this might have been wishful thinking).

Mizar in Ursa Major

Time: 2005-04-16 21:15 UT

With 10mm eyepiece it was very easy to split Mizar and Zeta Ursae Majoris.
