All observing logs for month 2005-05 (earliest log first).


Location: Billingborough (South Lincolnshire, UK)
From: 2005-05-02 20:30 UT
Equipment: Meade 10x50 Binoculars

Having acquired a set of Meade 10x50 binoculars I thought I'd give them a quick try.

Various objects

Time: 2005-05-02 20:30 UT onwards

With binoculars mounted on a photographic tripod I decided to have a quick run around some obvious targets to give them a test.

First looked at Jupiter. All four moons were obvious and easy to see and it was obvious that Jupiter itself was a disk. With something as bright as Jupiter I can see that the binoculars produce a slight "flare" (can't complain, they only cost 14.99).

Turned them on Saturn next. Can't actually see the rings (no surprise there) but it's obvious that I'm not looking at a circular object — the planet is obviously elongated on one axis.

Also managed to get a really nice look at M44 (the Beehive Cluster, AKA Praesepe Cancri, AKA NGC 2632) and Melotte 111.

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.

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.


Time: 2005-05-07 22:13 UT

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.

Naked Eye

Moon very close to Jupiter but cloud rolling in so decided to give it an early look while I had the chance.

Moon and Jupiter

Time: 2005-05-19 18:39 UT

Jupiter was about 1 degree from the Moon this evening. At the time of first viewing the sky was still very light. First looked to see if I could see Jupiter with the naked eye but couldn't make it out. Took a look with the 10x50 binoculars and saw it easily. Once I knew where it was I looked again with the naked eye and saw it with no problems.

With the binoculars I couldn't make out Jupiter's moons but the planet did have a very elongated look so I suspect I was seeing two or more moons but was failing to separate them.

Moon and Jupiter — Pictures via Mobile Phone

From: 2005-05-19 19:00 UT
To: 2005-05-19 19:06 UT

With the 10x50 binoculars mounted on a tripod I thought I'd try something silly and attempt to take some pictures via it with the camera in my mobile phone. No surprise that the pictures aren't very good but, at the same time, a couple of them turned out better than I'd expected. Here's one of the best:

Around this time the cloud started to really roll in so that was the end of the session.
