Location: Billingborough (South Lincolnshire, UK)
From: 2005-05-04 20:50 UT
To: 2005-05-04 21:50 UT (approximate)
Equipment: Sky-Watcher Explorer 130M
Meade 10x50 Binoculars

Seeing seemed reasonable tonight. No moon.

Didn't get a chance to look at Jupiter as it was obscured by the house early on and by the time it cleared the house cloud had started to roll in from the south.


Time: 2005-05-04 20:50 UT

With the 10mm eyepiece on the 130M I thought I could see the faint hint of a band on the planet's disk. Not really sure if this really was there or if my eye/mind was playing tricks on me.

As with previous sessions I kept getting the odd hint of the Cassini Division.

At just before 21:00 UT, while looking at Saturn with the 10mm eyepiece and 2x Barlow, had a meteor pass right through the field!

Titan was obvious and, with the 10mm and 2x Barlow, I noticed another faint point quite close to the planet (I'd estimate a couple of Saturn diameters away in the field). Wasn't sure if I was seeing another moon or perhaps a background star. Checked the following day with Starry Night and it seems that what I was seeing was Saturn's moon Rhea.

The International Space Station

Time: 2005-05-04 21:15 UT (approximate)

Naked eye this time (obviously). While having a break from the telescope for a moment saw a very bright satellite moving West to East, easily as bright as Jupiter. Saw it pass within two or three degrees of Jupiter. As it headed East it dimmed and disappeared from view as it past into Earth's shadow. Suspected at the time that what I'd seen was the ISS.

Checked the following day with Starry Night: yes, it was the ISS .


Time: 2005-05-04 21:30 UT onwards

Had another look at M44 with the binoculars and then turned the 130M on it using 25mm eyepiece. Very impressive. More stars that I'd care to count.

Noticed with the binoculars, reasonably close to M44, there's an asterism of stars in a roughly straight line. Got to wondering if it's got a name.

Did some checking on the web the following day and couldn't find any mention of it. I guess it's not an asterism of note. Checking in Starry Night it seems what I was looking at is comprised of the following stars (plus some others):

If anyone reading this recognises this asterism and knows a name for it I'd love to hear about it.
