Sep 1st

I managed a bin scan in clear conditions at 07:50 GMT but still no sunspots.

I also saw a waning gibboust Moon high in the West. The ray systems had gone but the southern craters, dominated by Tycho and Clavius were clearly visible, despite the bright sunlight.

Sep 2nd


Early evening was clouded out but I went out past midnight BST (00:10) or 23:10 GMT. Was it still Sep 1st or Sep 2nd? I'm as confused as you are.

I started with a bin scan at 00:10. The Moon was bright and Tycho's rays had faded somewhat since my latest look. I had my first sight of the leiades. I also saw M11, M15 and M2 quite clearly but M29 and M39 were lost in the Milky Way background. I also checked the visual doubles.

I used 2 cameras, 3 eyepiece combinations and loads of optical zoom combinations and whacked up a personal best 29 photos.



I then went after the Messier Catalogue for an upcoming writing project. After a lot of fiddling, I found the Wild Duck Cluster (M11). It was quite hard to see against the background Milky Way but I could make out the flying duck shape, just about. The globular clusters M2 and M15 looked larger than with the bins but I couldn't see any additional features, nor outer stars. The Pleiades looked great but I couldn't get the main asterism into the 1.7 degree field of view. Mars was low and shimmering a lot, showing some albedo features and a disctinctly gibbous phase.

The final piece of action was at 00:30 GMT with 10x21 bins. The Hyades were great and it was nice to see all members in the same field of view. I could see the main 8 Pleiades plus 4 fainter members. The Moon looked great and I was able to see too many craters to count but there was noticeable chromatic aberration, especially towards the edge of the field of view. The Usual Suspect doubles all split, although Alberio was rather borderline.

Sep 3rd

Bin scanned the Sun through thin cloud at 08:35 GMT but didn't see any sunspots.

It cleared up so I did a quick 10x21 bin scan at 20:40 GMT. I was able to see parts of the Milky Way with the unaided eye, so it was particularly clear. Jupiter even showed a moon. I was able to see all doubles and although Alberio split, I couldn't resolve any space between the components. The Andromeda Galaxy (M31) showed quite well and I was even able to see misty patches where M11, M13, M24 and M33 were. Melotte 20 showed up very well. It was probably as good as it could get with the small binoculars.

Sep 4th

At 05:20 GMT, Venus was hanging low in the east, so I managed a quick bin scan with the 10x21 binoculars. Although there was some scattered light (not unusual when viewing Venus), I could clearly make out a thin crescent.

I bin scanned the Sun on arrival at work at 06:50 GMT but didn't see any sunspots.

I went out for some fresh air at 08:00 GMT and took a look at the Moon. At the last quarter stage, libration had made Grimaldi very difficult but the southern craters and Appennines were well placed near the terminator. I tried again for Venus, more in hope than expectation.

Sep 5th

After a cloudy day, it cleared enough at 16:40 GMT to allow a nice view of the Sun but, unfortunately, there were still no sunspots.

Sep 6th

Bin scanned the Sun in clear conditions at 07:40 GMT but didn't see any sunspots. I also saw a waning crescent Moon high in the sky. There aren't usually many craters visible on it and Grimaldi was difficult, due to libration.

Sep 7th

I woke up early. Although there was a fair bit of cloud about in the pre-dawn sky, I managed to see the Moon and Venus with my binoculars at 05:00 GMT. There were a surprising number of craters on the terminator and a lot of earthshine. Venus showed a 30% phase.

It clouded right over soon after dawn but I was able to get a clear look at the Sun at 11:55 GMT. I could see limb darkening but no sunspots.

I did a hydrogen alpha photo shoot at 17:00 GMT. The Sun was quiet, with no surface action but there was a nice prominence:



At 21:00 GMT, I had returned from walking Charlie and seeing the stars of Aquarius for the first time. Shows how bad light pollution is. Although I was tired from a hrd week, the night was too good to miss. Having read "Astronomy Now", I decided to track down M52 in Cassiopeia. That was an adventure in itself, as the whole region was alive with Milky Way stars and I had some "false pots" by finding some fainter clusters on the way. Once found, I realised it was a far easier target than I'd previously imagined. I also potted M34. I had a quick scan round the Usual Suspects and I saw the full extent of the Andromeda Galaxy (M31). I also checked out some of the fainter deep sky objects visible, including M10, even though it was well down. The Wild Duck (M11) looked about as good as it's ever been. I couldn't see M29 or M39, as they wer elost in the Milky Way background.

I returned an hour later do do a constellation shoot (in order: Aquila, Cassiopeia Cygnus, Summer Triangle):



Sep 8th

Bin scanned the Sun through thin cloud at 09:15 GMT but didn't see any sunspots.

Sep 12th

I finally managed to see the Sun from Hilversum (Holland) after some cloudy weather on both sides of the English channel. Although the Sun was low down (it was local time 18:30, 16:30 GMT), I could see limb darkening but still no sunspots.

Sep 13th

It was clear enough to do a bin scan of the Sun at 10:45 GMT. Although there was thin moving cloud, only faint sunspots would have been missed.

It was actually clear in the evening at 22:00 local time (20:00 GMT). Street and security lights made viewing difficult and the Wild Duck cluster (M11) was invisible but I managed to see M13 and the Andromeda Galaxy (M31) amongst the usual binocular double stars.

Sep 14th

Bin scanned the Sun at 06:45 GMT in great conditions but still no sunspots. I also tried to find Venus but without success.

Sep 15th

Bin scanned the Sun at 09:05 GMT back in England. The conditions were very clear but still no sunspots.

The hydrogen alpha view at 14:00 GMT wasn't much more promising, with only some granulation features and a single prominence, although some more showed in the photos:




I went for a bin scan at 22:45 GMT. The summer constellations were well to the west and the Wild Duck cluster (M11) was low but I was unable to find it. I was able to pick out both globular clusters, M13 and M92 in Hercules. I found M29 against the Milky Way but missed M39. All regular suspect doubles were visible and split easily but I missed M2 and M15. In the east, I saw M52, M34, the Pleiades and Hyades well but didn't see the open clusters in Auriga (probably low elevation). Mars showed a definite disc but I didn't see any surface detail, nor did I expect to.

Sep 16th

I went out again at 23:15 GMT to do some constellation shoots, having uncovered the technique of using the histogram function the right way. First up was Cygnus:



Second up was the Plough, not bad considering the low elevation:



I managed to catch the main asterism of Ursa Minor but only just:



I'd tried the Square of Pegasus a few times but this time, I got it:



I caught Cassiopeia and Perseus together:



The next Pegasus shot even caught some of Aquarius:



Although Lyra didn't come out as well as I hoped, I caught parts of Draco and Hercules:



Bin scanned the Sun at 11:35 GMT through thin cloud but didn't see any sunspots.

Sep 17th

Bin scanned the Sun through thin cloud at 08:05 GMT and there were still no sunspots.

Sep 18th

Bin scanned the Sun in a clear sky at 06:50 GMT and there were still no sunspots.

Sep 19th

Bin scanned the Sun through moving thin cloud at 11:40 GMT and there were still no sunspots.

Sep 22nd

Bin scanned the Sun through moving thin cloud at 09:00 GMT and the words "Maunder Minimum" sprung to mind.

At 18:55 GMT, I went on a dusk patrol with the binoculars. There was a great lunar landscape with Tycho's rays starting to show. I caught what I expected to be one of my last views of Jupiter when I saw 2 moons. Spica and Antares were both low and only showed to the binoculars. As Deneb and Vega were visible, I scanned for Alberio and it split, although the secondary component was barely visible.

I returned at 19:20 GMT with the Maksutov and 2 cameras. I could see all four Galilean moons but could only just make out the equatorial bands but with 103x magnification, I could just make out a third band. Un fortunately, my attempts to photograph the planetary disc and moons failed.

However, I had more success with the Moon:



The following shots were taken with a telescope magnification of 308x, using optical zoom on both cameras to get really close up:



Unfortunately, the very high magnification shots had the light spread out over so large an area, I couldn't capture any detail, suggesting a lower maximum magnification of around 1000x.

Sep 24th

After a wet Sunday and Monday morning, it cleared by mid-morning enough for me to bin scan the Sun at 10:15 GMT. Still no sunspots, though.

The evening was more of a "scratcher's night". There was lots of cloud, of all thicknesses scattered by moonlight and it was moving too quickly for any hope of a photo shoot. Nevertheless, at 21:00, I went out for a bin scan. The Moon was low but showing lots of craters near the terminator and Tycho's rays were becoming more prominent.

Melotte 20 showed well but I could only see the main asterism of the Pleiades. I couldn't see M11 through the clouds to the west but the Andromeda Galaxy (M31) was visible through thin cloud. The only other object I saw was Mizar/Alcor.

Sep 25th

I bin scanned the Sun in a rare clear sky at 06:55 GMT but still no sunspots.

Sep 26th

I bin scanned the Sun through thin cloud at 13:35 GMT but still no sunspots.

Sep 27th

I bin scanned the Sun in a rare clear sky at 07:15 GMT but still no sunspots.

Sep 30th

I bin scanned the Sun through thin cloud at 12:45 GMT but still no sunspots.
