A Clear night! Tried to get Comet ISON, but failed to get it in the field of view.
Put the DMK camera through its paces. Tried the galaxies in the Leo Triplet M66 and M65.
Finally packed up at half 1.
What a disastrous night! Everything was working fine until I started auto-guiding.
The camera gave up the ghost. I put on a friends CCD camera and started taking images.
Then that decided to stop downloading images as well. So I only got a five images in the bag.
But here’s the result. At least I got something.
Looks like Saturday night will be clear, so I will sort the camera out and have another go tomorrow…
Missed two clear nights as I was too tired to get up in the early hours after the Moon had set.
But I finally got a clear day at the weekend to capture the Sun.
Close up of Active Region 1726.
Last night I finally got a moment to make a montage of my Milky Way images I took in the early hours in The Maldives. A combination of 3 10mm lens images, showing the Milky Way from Cygnus on the left, right the way over to The Southern Cross on the right.
I’m pleased with that one.
Being such a clear night, I thought I would try and bag Comet ISON as it was so close to Castor in Gemini.
At 16th magnitude, I didn’t think I had a hope.
But if you don’t try.
My trusty C2A software led me from Castor to the field the comet should have been in. I took 15x 2 minute exposures and stacked them on the comet, which I could see slowly moving almost in the centre of the field of view.
The comet is round and the stars are trailed. RESULT!!! Get in there!
Here is the whole field with the subs stacked on the stars cropped in the area around the comet, showing some faint galaxies in the same field of view. The comet looks trailed in this image.
I’d like to know the magnitude of the galaxy marked “?” in my image.
A much tighter crop of the area shows the comets trail distinctly.
On the 15th of February a big lump of rock will pass extremely close to the Earth.
So close in fact that it will come closer in than the geosynchronous satellites.
Now that’s close!
Asteroid 2012 DA14 was discovered in February 2012 and is about 45 meters in diameter and will pass close to the Earth at a distance of only 13,870 miles.
THERE IS NO CHANCE OF IT HITTING THE EARTH!
Moving northwards it starts the evening too far south for us to see. It will be at its closest to Earth at about 18:00h on the 15th of February, when it will be too far south for us to see in the UK. For those further south who will be able to view it will probably disappear into the Earth’s shadow for about 18 minutes, 4 minutes after its closest approach.
At this time it should be at about magnitude 7.4 and at its closest the the Earth. So although it won’t be visible to the naked eye (just), it should be easily visible in binoculars or a small telescope as a fairly bright “star” moving northwards through the background stars.
For those further south who will be able to view it will probably disappear into the Earth’s shadow for about 18 minutes, 4 minutes after its closest approach.
THE CIRCUMSTANCES OF THIS PASS.
Unfortunately my prediction software failed to take account of the gravitational effect of the Earth on the objects orbit as it passed the Earth. My prediction published here previously was about 2 hours behind.
I have now run an ephemeris using the HORIZONS Web site for my location in mid UK:
The asteroid rises just after 19:50h that evening with an apparent magnitude of 7.59.
Heading quickly north, it passes to the east of Denebola in the tail of Leo at around 20:00h, by this time it has faded to 8th magnitude.
By 20:20 it will be passing through or very close to Melotte 111, the star cluster in Coma Berenices.
At 21:00h it will have faded to magnitude 8.6 and be located in Canes Venatici and still heading swiftly north.
It will cross through the handle of The Plough around 21:32h, now just below 9th magnitude.
Thankfully the BAA Minor planets section has produced a prediction based on a location on the south coast of the UK and produced two very fine finder charts for that evening.
Below are their images of the predicted path that evening:
I had yet another trip to Wales. So I took my camera and new lens along with me in hope. This was the first time I had enjoyed a trip to the much darker skies of Wales without rain or the full Moon. So I made the most of my evenings as they were clear.
A view of Tresaith from the beach with Orion rising behind.
The view from the same vantage point out to sea.
The plough near the cliffs from the same beach.
Orion passing between trees.
The Milky Way in all its glory.
Stargazing Live starts tonight on BBC 2.
Don’t forget to attend some of the stargazing live events organised near you.
I will be involved with two of the three events organised by Northampton Natural History Society.

19 January, 18:00-20:00. Salcey Forest, Hartwell
Apologies, but due to the icy weather and snow forecast for the end of this week, the event at Salcey Forest has had to be cancelled.
Please feel very welcome to come along to our next meeting.

A brief clear spell and I was ready.
Setup on Comet LINEAR C/2012 K5 first to get a few subs this time for a better image.
Then used the 5x Powermate with the DSLR to try and get a close up of the Trapezium in The Great Orion Nebula. You cannot almost see the other two trapezium stars as blobs on the side of the brighter stars.
Two nights. Two clear spells.
Just need a clear all-nighter now to really get in the mood.
The clouds finally parted at a time when I was able to get out and do some astronomy.
It seems such a long time ago since I’ve been out.
I wanted to test my new 10-20mm lens that my wife gave me money towards for my combined Xmas & birthday prezzie.
Despite the light pollution from my back garden I was able to reveal the Milky way stretching right from Gemini (Open Star Cluster M35 is down in bottom right), into Cygnus (Deneb top left).
I see that I am going to have so much fun with this lens…
I then set the scope up to take an image of Comet C/LINEAR 2012K5.
It was in the southern part of Auriga and just visible in my main scope as a hazy smudge.
Unfortunately, just as I got 3 images in the bag, it clouded over again bringing my great observing start to 2013 to a crashing halt.
A small taster of what might be coming later in the year?
