Quick Observing report

The cold air tonight reminded me that there actually sometimes is a starry sky above my head. Seeing the clear, star pricked night, I assembled the Celestron 130SLT and eyepieces and quickly set it up outside. Not quick enough as a band of fast moving cloud headed between me and the targets. Defeated, I returned inside.

Not too long afterward, I returned and set up under a clearer sky with slower clouds. I took with me the Greenkat spotting scope as well. My three intended targets for the night were Jupiter, Uranus and the Comet 103P Hartley, which is breaching the magnitude 6.5 according to Heavens Above (finder chart here). My intention was to direct the main telescope straight onto Jupiter and Uranus and use the spotting scope’s wider field of view to scan for the comet before zooming in on it later, as I have done with previous ones.

This didn’t go quite to plan as a combination of the strong light of the Moon and neighbours popping by for a look meant the comet hunt was eventually called off. Although I did get a glimpse of Hartley, it didn’t seem quite good enough for a swing round of the Celestron.

Instead I concentrated on the brighter objects, taking in the turquoise Uranus before showing off Jupiter and the four Galilean moons to four neighbours. Three of the satellites were arranged in a similar way to the handle of the plough, all on one side of the planet. The fourth, Io, sat just off the limb, easily resolvable in the 9mm and 4mm eyepieces, but too close for the 24mm one to pick out. Just passed opposition, the giant planet is enormous in the eyepiece. As well as the remaining equatorial band, detail could be seen of the zones and caps, which is quite unusual for me to spot.

After this, a neighbour wanted to look at the just passed full Moon, so we swung onto that, with views of shadowed craters on the limb to see. With that done and the cold biting into everyone, the session was wrapped up and we headed back into our houses.
