This has to be one of the most awe inspiring images ever taken by the Hubble space telescope it is of M 16 the famous Pillars of Creation located within the Eagle nebula in the constellation of Serpen. These massive gas clouds light years high are the very birthplace of countless stars some of which can be seen burning bright through the dark dust clouds and frozen hydrogen from which they were created.

If you look closer at the middle finger towards the top you can make out one of the stellar eggs( stellar Nebula ) from which the stars are born drawn in by the relentless pull of gravity over millions of years the gas clouds slowly condense downwards the enormous pressure forcing the frozen Hydrogen atoms ever closer and as the temperature soars to a staggering 10 million degree's Centigrade Nuclear fusion takes place lighting up the star

Viewing Log 1 February 2012 at Uffcott by Pete Chappell

NGC 2362 (also known as Caldwell 64) is an open cluster in the constellation Canis Major.

Michael Partridge from Swindon Stargazers had arranged for a viewing session at Uffcott. This meant I would miss an evening of playing Bridge, as I also play on Thursday night I think I could miss one night for the week? I had been out the previous Monday in cold weather and tonight it was going to be colder and with a stronger wind.

Mike had arranged that we meet up at 7:30 and do about two hours as several people would be working the following day, nice to get out during the week but you cannot go to crazy with viewing if you have to get up and go work the next day? Not being in work I did not have this problem to worry about!

I was the first to arrive at 7:25 closely followed by Mike. The temperature was already -2 when I left home and I noticed a strong wind on top of the hill at Uffcott which would make the weather feel colder. This time I decided I would use my William Optic’s 80mm refractor on an EQ3-2 mount, this gear had not seen daylight since the 15th of October last year. I thought this equipment might be easier to use (as it gives a wider field of view) for viewing my list of deep sky objects for the evening. All of the objects were from the Herschel 400 Observing List. I was now up to February and keen to see many objects tonight before the cold would drive us in doors! Before I started on the deep sky list I wanted to view Venus in a telescope as I had seen this object many times in the sky recently (naked eye only) without having a good look at it. After this I went to Uranus and is normal now I call over Hilary Wilkey as she likes to see this planet and then try and find it for herself. Final solar system object was Jupiter, I could only make out two moons? Asking Mike to have a look, he said he could only find two, several other people pointed this out as well!

That was the solar system out of the way for the timing being, now to carry on with my Herschel list. Most of the objects planned tonight would be Open Clusters (OC), the first three NGC’s 2354, 2362 and 2360 I could not make out. In case the GOTO equipment was out for some reason I went back to Sirius to check the accurateness of the GOTO equipment. Sirius was in view, so there was another problem? Went back to NGC 2354 and could not make it out, could only be one problem with the moon being 71% illuminated and making shadows on the floor! I now gave up on my list and decided to view brighter Messier objects, these hopefully the moon would not block out? I could not make out M45 as the moon was very close to this OC and this was the brightest Messier object in the night sky! After I had given up with my planned list I went and had a look through other members’ telescopes that had turned up to view. It is nice to view through other equipment, if you are thinking about getting a new telescope it is far better to look through one and see what it can do, that way you do not buy a ‘White Elephant’ that sits in the house and does not get used again! On one of my walk a rounds (trying to keep warm) I counted nine people, this is the most we have had at Uffcott. The lay-by was full, so if Swindon Stargazers are going to use this area again it will have to be a reverse to the East Kennett site as that place can hold many more cars but has a higher volume of traffic going by. The only objects I looked at was M41 an OC below Sirius and M42 and 43 in Orion. I showed several people how to find M41 and M79 by star hoping to the objects, helps to have a star atlas with you! Several other objects I tried to find were not in the eye piece, I think the cold temperatures were affecting the drive train for the telescope. When I selected a command to slew to a new object, one of the drive train would judder and then move, this I think was affecting the accurateness of the telescope? I tried for NGC 457, the Owl Cluster in Cassiopeia and could not find the two main bright stars of this OC. Time to give up I thought but then noticed Mars had risen above the eastern horizon, managed to locate this planet but could not make out any real detail. I was using a Televue Ethos 13mm eye piece in a doublet Apo telescope, probably my best combination for viewing objects and still could not make anything out, also the angle did not help as Mars was still very low. How to kill your eye sight for the evening (not including white light), look at the moon and yes it killed my eye sight! The crater Copernicus (56 miles by 56 miles) was just coming in to day light and looked very good to view, there were several other craters that took my attention especially in the Mare Imbrium (Sea of Rainbows), crater Eratosthenes was the main one which you cannot see at a full moon.

By now it was 9:15 and my fingers were getting very cold even though the rest of me was okay, it does help to go out well protected. Working a GOTO telescope I need thin gloves to operate the hand controller, the best I have found is wind cheater gloves that I use while playing golf. These keep the wind out and the cold for a reasonable time, the session we had was very cold, by the time I packed up the temperature had dropped to -4 but to my surprise there was no frost on any of the equipment or the car. I guess the dew point was well below freezing point as we have had no rain for over a week and the air had been very dry?

Looking forward to the next star gazing session with this group? If you are interested in coming out with us, just drop Robin Wilkey a line and he will add you to the list. Only way to learn the night sky is to get out there and view!
Until the next time, clear skies and just a bit warmer please?

Viewing Log 14 January 2012 at Uffcott by Pete Chappell

This was going to be the first viewing session of 2012. I had planned this session about five days before hand, sent out e mails to all the regulars and hoped we would have clear skies? I got replies from Michael Partridge, Robin and Hilary Wilkey (all from Swindon Stargazers) and Peter Eslick and Jon Gale (both from Wiltshire AS) saying they could make the session. Arranged a time for 19:30 onwards and would meet at Uffcott as usual, this place was going to be first time for Michael, Robin and Hilary. I was the first to arrive at 19:25 and was met with a wonderful clear but cold (minus one according to the car) sky, could be in for a good one tonight was my thought?

I have a new plan for this year, my project is to view most (if not all) of the Herschel 400 Observing Guide by Steve O’Meara’s. This will require me to do a viewing plan before I go out, something I do not normally do, at all! So during the afternoon I went through the book and picked out my targets for the night. The book is split in to monthly targets and over a course of about seven nights, you should see all of the targets Steve O’Meara has chosen. After reading and writing down the targets, I chose four nights and 17 objects to view, I packed up the car and went off to Uffcott.

For this session I would be using my trusted eight inch Meade LX90 and various Pentax XW eye pieces. While setting up the telescope, Michael was the first to arrive and said WOW! The sky is really clear here, had to agree with him! After doing my set ups, I went off to Jupiter as Michael said he could only find two moons using a 15x70 binoculars. I had to agree with him, two of the moons were not on view, this was a first for me.

NGC 2022 is a planetary nebula in the constellation Orion

Turned out, Ganymede was in front of Jupiter and Europa was behind the planet as viewed from planet Earth. Hopefully come back to Jupiter later on and see what the moons were doing? I left Michael to his own items to view while I started on the Herschel list. January and first night with four items to view: New General Catalogue (NGC) 1647, an Open Cluster (OC) in Taurus was the first object to view, this OC is 3.5 degrees north east of Aldebaran and was a pretty good object to view. In fact most of this short list was going to be OC’s. NGC 1817 and 1664 were the next targets, these were okay to view. I had trouble in finding 1664, as my list said 1644 and the hand controller said it was not up yet? Does help to get the correct numbers! By now Hilary and Robin had turned up and their comments were very similar to Michael’s, WOW and a few other good words. I was now in Auriga and looking at NGC 2126, a dim OC which most people would probably not look at? Next was NGC 1857, again in Auriga and an OC, again this was a dim OC. NGC 1907 got a good report from me, this OC is much tighter than the rest I had seen tonight and had brighter stars at magnitude (Mag) 8.2. The first Emission and Reflection Nebula of the night was NGC 1931, this looked similar to M42 but much fainter, but still good to look at! The last two, Jon and Peter turned up within 20 seconds of each other, so the lay-by was full and hopefully our night vision would not be affected by car head lights? Jon had brought his trusted Vixen on a mini Porter Mount while Peter was going to set up his LX90 and take some pictures of Jupiter. My last object in Auriga was NGC 2281, a good looking OC with some bright stars within it.


I was now going to turn my telescope to Orion and not look at M42, as it is not on my list for the night! First object was NGC 2169 a nice bright OC at the northern end of Orion, not far away is NGC 2194, again an OC and better to look at with a bigger telescope. The last OC for the night was NGC 2186, a dim object to view. While I was going through my list there was a lot of noise coming from Peter (who had parked his car in front of me), seems like he could not get his telescope to work, several times he had reset the telescope with the same results on the hand controller. The hand controller had said ‘major fault with the motors’, this I had seen and had before. Probably the battery is flat was my answer to Peter, it cannot be as I charged it up earlier on today and the current was showing full! Still I would go with a flat battery route was my answer. Peter would have to wait until I had finished my session to check out if his battery had packed up. Next on this list was the first Planetary Nebula (PN) in NGC 2022, this PN is close to Betelgeuse and took a while to see clearly. I brought Jon over to have a look and he could not make it out clearly, he suggested I put a higher powered eye piece in and see if that did the trick. So I changed the 20mm for a 10mm and that did the trick, this PN is not that big compared to the Dumbbell Nebula (M27) in size, but at Mag 11.9 posed a problem. The book says it is more like a swollen star, more hard to pick out! Our first galaxy was NGC 1964 in Lupus, as hard as we tried, we could not make it out, as Jon said the jury was out on this one. Four people had a look and could not make it out, the weather was not helping now as cloud was starting to come in and affect the viewing. I will have to come back to this galaxy at another viewing session and hopefully see it? NGC 1788, a Reflection Nebula is right on the border of Orion and Eridanus, we could make this one out okay. Our final target for the night was NGC 1980, a bright Emission Nebula (EN) only half a degree below M42! I have probably seen this EN quite a few times in the pass while looking at M42 and not realised it? We would have carried on but the cloud was now coming in very thick and made viewing nearly impossible. Time to call ‘White Light’ and pack up the gear and head for the local pub and have a few cups of coffee to warm us up!


During the evening I did stop the 400 list and tried Jon’s Vixen telescope. This is a manual telescope, something that I do not use much! Looking at a star chart I managed to pick out M41, about 4 degrees below Sirius, the Dog Star and the brightest star in the night sky. The other target that I found was M79, a Globular Cluster in Lepus.


We had been out for two and a half hours and I was up to fourth night for viewing the 400 and only had one failure in NGC1964, which we could not see, it might have been there but who knows? Only another 386 to go! While I was packing my LX90 up, Peter tried my battery on his telescope and it seem to work correctly, so looks like Peter might have to get another battery in the near future?
By the reactions I got from Hilary, Michael and Robin, I think they will be coming out to Uffcott again as it is a lot closer (to Swindon) than the East Kennett site, probably darker and more important, the road is not used by as much traffic, keeps your eyes night vision?
Hope we have many more clear skies during 2012?

Viewing Log 25th March, 2017 at Uffcott by Rob Slack

M51 - The Whirlpool Galaxy in Ursa Major
After weeks of rotten weather, at least for astronomers, we finally had a clear night forecast on a weekend and no Moon either - it was simply too good a night to pass up. So I packed scope and all into back of the car and drove out to Uffcott, just to the southwest of Swindon, last Saturday the 25th March.

Upon arrival, it was dark, at least looking to the south, clear but a little windy at times, not ideal, but still worth a punt!

Once I had set up my Helios Newtonian with a two inch eyepiece, FL of 32mm and allowed it to settle for half an hour I set about locating a few targets I had in mind from the Sky Briefs. Normally at home in the suburbs of Swindon, I would struggle to to find these targets, due to the light pollution.

So I started by using the star Alkaid in Ursa Major, to last star in the milk pan handle. Using this as a starting point I first scanned around to the right of this star to locate the Whirlpool galaxy, M51 and it's partner NGC5195. Moving further to the right I next encountered M63 the Sunflower galaxy before shooting right past Alkaid to find the very fuzzy blob of the Pinwheel, M101.

Then I set about locating two old friends, galaxies I used to observe quite a bit when I lived on a farm, to the north of Bath - M65 and M66, both edge on galaxies in Leo, on the lions thigh I guess. These are great targets and although books claim they are magnitude 9, they look brighter than that, maybe because they are edge on.

Staying with the two inch eyepiece and now an OIII filter I had a look at M42 in Orion, before Orion sets till next winter. A fabulous sight, no matter how many times I observe it and the OIII filter really brings it alive!

Final target of the night was Jupiter. Again cannot quite get on Jupiter at home, it is too low. But From Uffcott, it looked great, even though the wind did a good job of rocking the scope.

To all out there with fancy GOTO scopes, you might consider my little challenge rather easy peasy! But I have no such tech and have to star hop! Apart from M42 and Jupiter, none of the objects are visible even in my three inch finderscope, so I had to literally sweep the general area where I knew these objects were, makes all the more rewarding when you do finally nail them in the centre of the eyepiece.

Soon after that I packed it in, as I had forgotten my gloves and hands were flipping cold.

As the clocks have now gone forward and the evenings get lighter now, I was glad I pushed myself off the settee and away from the Voice UK and got out there and did some observing - rewarding.
