Christmas Eve Spectacular!

Twas the night before Christmas, when all through the house Not a creature was stirring, not even a mouse;

Christmas Eve, and you're snuggled cozily in your den. A glowing fire gently crackles and pops in the fireplace, and your head starts to droop as you nod off. Just then, something cold and wet nudges your cheek. You open your eyes to stare directly into a large black nose. It's time to take the dog for his walk.
Grumbling in vain, you put on your coat, snap the leash onto the wiggling dog's collar, open the door to a rush of cold air. You step outside and enter a magical landscape.
The night isn't dark, it's glowing with a silvery-white light. Up above, the 98% full moon looks huge and clear in the azure sky. It just might be the brightest moon you've ever seen. That's because it's the highest-riding full moon until the year 2023.

And not far from the beautiful moon glows fireplace-red Mars. This Christmas Eve, Mars is at its closest to Earth for the next nine years. Mars is also "at opposition." That's astronomy-lingo for "directly opposite the sun." It means Mars is up whenever the sun is down: on Christmas Eve, the Red Planet will be visible all night long.

As Christmas scenes go, it doesn't get much better. Gliding in formation across the sky, the moon and Mars seem so close you could almost reach up, grab the pair and bounce them down the street for Fido to retrieve.
Or maybe you could lasso them, as George says in the movie It's a Wonderful Life. "Just say the word and I'll throw a lasso around it and pull it down. Hey! That's a pretty good idea! I'll give you the moon, Mary...."
In the years ahead, NASA is going to lasso the moon. NASA's giant Ares rocket, still on the drawing board, will take form and then take mankind back to that brilliant silver orb where scientists will learn how to harness the moon's powers.
Plans are to establish a lunar base for exploration and use the moon's surface as a springboard to even further destinations. At the moon's poles there is evidence of hydrogen and perhaps actual water frozen in the soil. Furthermore, ordinary moonrocks are made of minerals that contain more than 40% oxygen. These are resources that can be used to produce rocket fuel, breathable air and a welcome drink on a dry, dusty world.

Maybe on some future Christmas Eve, one of us will step outside of our cozy lunar cabin and walk our space-suited dog with long, floating steps down some dusty lunar road. We'll look up and say, "There's a pretty full Earth tonight!"
But on this frosty Christmas Eve, your feet crunch Earth's cold ground with a crisp clear sound as you walk back toward the house looking up through the silvery stillness at the lovely moon and its bright partner, Mars. The only other sounds you hear are dog tags jingling like sleigh bells. Suddenly a shadow flits across the moon. A cloud? A plane? A sleigh! Maybe those were sleigh bells you heard!
Smiling to yourself, you open the door to go back inside, taking one last glance at the night sky and one of the loveliest heavenly sights you’ll see for years.

The Pleaides M45

Beautiful image of M45 taken on 10th December.
The Pleaides is a wonderful cluster of stars that is now visible high in the South East. I used to call it the 'Little Bear' because it looks like a minature version of Ursa Major 'The Plough'.
This cluster is very special as all the bright stars are blue and very hot. This makes nearby gas to glow because of the energy and produces nebulocity. I have taken images before of M45, but could not capture the glow. This time I managed to capture M45 with it's blue nebulocity and looks beautiful!
Tonight the sky is clear and the Moon sits low in the Southern sky, but it is frosty and really cold, I really didn't feel like going outside tonight. My next task is to try to image the Horsehead Nebula and Flame Nebula. I have never seen these before, but judging by the results of the Orion Nebula, i'm sure I can capture a reasonable image.
I'm beginning to think about changing some of my equipment, the Skywatcher 130m is brilliant for planetary work with the webcam, but I cannot attach the Canon 350D. Should I replace the scope with a Skywatcher ED80 refractor? This can easily be attached to the SLT mount...hmm....still thinking!

Orion Nebula M42 and Running Man Nebula



These images taken on 10th December, the lower image is a closer view of the blur at the top of the Orion Nebula image.
Cold, clear and frosty evening and a beautiful sky! At first I took about an hour of images of M45 Plaiedes while I waited for Orion to rise over the rooftops. I have waited a long time now to try to capture a more detailed image of the Orion Nebula with my Canon 350D. This is my first attempt and results are stunning! I played around a bit with colours which has given me several different results, the one above is my favourite!
The image is composed of 60 x 30s images, stacked in Deepskystacker and processed in Photoshop 7. Canon 350D and Skywatcher ST80 telescope.
If you look closely at the lower image you can see a shadow of a 'running man' this is a feint nebula above the main Orion nebula

Comet Holmes 17p


These images taken of Comet Holmes on Sunday Night 11th November with the ST80 telescope and Canon 350D camera - wonderful!
The comet is gradually becoming bigger but more transparent, you can clearly see stars through the coma and the colour is stunning. Apparantly, Comet Holmes lost it's short tail a couple of days ago, but even then it was difficult to image. I think the bow of the comet is facing the Earth and the tail (what there is of it) is trailing behind.
Comet Holmes has reached a diameter of 1.4 million Kilometres, this makes it the biggest object in the solar system, bigger than the Sun in size but not mass.

Latest M33 and M74


M33 Pinwheel Galaxy and M74 Phantom Galaxy

Beautiful clear night on Sunday, crisp and frosty!
I wanted to try again at M33 with the ST80 and 1 minute exposures. I can't really go further than that with the mount because of star rotation. I'm not sure if Deepspacestacker will correct larger rotations.
Much more detail than my previous attempts, but I can't bring out the colour, probably because longer exposures are still needed. Still..i'm still amazed that I can capture this galaxy at all!

I am even more amazed to capture an image of M74 galaxy! This feint little object close to M33 has a magnitude greater than 10.0. Cannot even see it visually! You can see the shape of this spiral galaxy, but not much detail...i'm dead pleased with it though!
I've got to say that the Celestron SLR GoTo mount is brilliant, no way would I be able to find thse objects with my Skywatcher 130m. They are face-on spiral galaxies and are a sod to find!

Frogspawn in Space?


Another image of Comet Holmes 17p taken on 8th November.

This time I used 30s exposures with the Canon 350D and 200mm lens. Stars are streaking and there is movement from the Comet, but a nice image!

Comet Holmes has grown in size, but has become more diffuse. It can be seen easily with the naked eye but I also had a look with the Skywatcher 130...WoW! It is enormous...the Comet completely filled the FOV with a 17mm eyepiece. This is the biggest Comet since Halley-Bopp back in 1997!

Fireworks in space!




I like this image of Comet Holmes...this image produced from two lots of images stacked in Deepskystacker (DSS)
A spectacular object and now larger than any planet! Whatever caused the outburst of this comet is better than any terestial firework on bonfire night!
Since becoming interested in Astro-imaging i'm amazed at the number of comets that are about and can be seen from Earth, this one without a telescope. It's just knowing where to look. I'm surprised that this comet has not had a mention on television, it is so easy to see!
Happy Birthday Website!!!
My website has now been running for two years and I have had more than five thousand hits! (alright...a lot of them mine) ...but when I look at the statistics I can see that I have had hits from all round the world...brilliant!

Comet Holmes 17p



A couple of nice images taken myself last night of Comet Holmes.
Amid the pops and bangs of fireworks I managed to take some images of the comet with my Canon 350D on a tripod with the 200mm zoom lens. Although the sky was clear, there was a lot of smoke and mist in the air. The widefield view was taken with the 200mm zoom lens set at 50mm while the close up view was taken with the zoom lens set at 200mm.
I would like to try imaging the comet with the ST80, but I will wait for a clearer night!

Halloween Holmes


Comet 17P Holmes....Spooky!
At the moment in the constellation of Perseus, lies a strange object bright enough to view without a telescope. It is the Comet 17P Holmes which started as a very feint object a couple of weeks ago and then suffered an 'outburst' which has increased it's brightness to that of a bright star!
It's coma is ghostly!
Problem is...I can't see it at the moment because of the total cloud cover. I hope to capture an image as soon as the cloud clears...watch this space!

Wildfires and Discovery Launch



I found out today by accident, that the Space Shuttle Discovery was launched today on it's way to the ISS again to build on more of the Space Station.

Not a mention on today's news!

It seems that the only way to find out these days are from the NASA site directly including the super NASA TV site.

Only a couple of days ago I was watching the ISS pass overhead, the rest of the country total oblivious to this bright star (without lights) which can't be missed and wonderful to view!

Meanwhile, on the other side of USA, wildfires are causing havoc in California and making the news. The satelite pictures are superb, but again...why don't they show them on TV?

Last week the Russian Soyuz craft docked with the ISS, again...not a mention in the news.

M33 Triangulum Galaxy


M33 Triangulum Galaxy
This image was taken with my Canon 350D and 200mm zoom lens mounted on the Celestron SLT. Quite a bit of processing to bring out this feint object, but you can clearly see the arms of this face on galaxy. I have tried to find this with my Skywatcher 130m but just cannot find it!
The SLT is brilliant, it finds objects with no problem once the mount has been set up correctly.

Andromeda again!

This image taken on the 17th October.
Another go at M31, this time with the 200mm lens fitted to the Canon 350D and mounted onto the ST80 mount. I also used dark frames and a flat frames with this one for the first time. I must admit that I don't fully understand flat fields. The ones used here were shots of an empty twilight sky. I love the widefield view of the stars with Andromeda in the centre. I still can't find the 'ulimate' image, but i'm trying hard!
Weather at the moment is gorgeous, warm sunshine and freezing cold but clear nights

ISS pass in twilight

This nice image taken on the 17th October at 7.05pm.
It's great to see the ISS pass over in clear skies. I tried to take some stills but can't see much detail. The image above was taken with my Canon 350D, 20s exposure, ISO 400. ISS travelling from West to South East. Quite a difficult shot really as it was still light and the settings were an educated guess.

Andromeda and M33




Here they are...my best yet Andromeda Galaxy and first M33 Triangulum Galaxy.
Wonderful Indian Summer weather, temp still in the 70's and some nice clear nights. This morning I woke up and looked out of my bedroom window and saw a beautiful sight, the cresent Moon and Venus close together!

On Friday night I set up my camera and ST80 to have another go at Andromeda. Took nearly an hour to set up and centre Andromeda with the 350. I decided to try 45 sec subs as this seemed alright on my test images. I left DSLR Shutter to take 120 exposures of Andromeda and this worked fine. This time I used JPG format rather than RAW.

Later I tried the same with M33 - The Triangulum Galaxy. The results are impressive after a few hours on PhotoShop.

I really need to remember to take Darks as the results have a lot of noise and blue pixels which i'm sure can be ellimated. I must admit that I got quite frustrated with these images because you never know when to stop processing. I'm sure that someone who knows Photoshop better than me could produce superb images from the raw data.

Dawn Spacecraft Launched


NASA's Dawn spacecraft is on its way to study a pair of asteroids after lifting off today from the Cape Canaveral Air Force Station at 7:34 a.m. EDT (4:34 a.m. PDT).
(Click the picture - it's brill!)


My name is now digitally on it's way to the origin of the Solar System contained in a microchip aboard the Dawn Probe...cool!


The spacecraft will arrive at the asteroids Vesta and Cares sometime in 2011.

Harvest Moon

A beautiful Harvest Moon tonight!
The sky is perfectly clear with a real Autumn nip in the air, forecast tonight is frost as high pressure sits over the country. I wonder how many farmers are out in the fields bringing in the harvest in the moonlight?
It is certainly bright enough here!
Took this image from my front garden with the Canon 350D set up on a tripod.

Andromeda Galaxy


This beautiful galaxy has set me a quest - to take a beautiful image of it! I'm getting there slowly!

Now high in the East, Andromeda can be found easily even with binoculars, it is seen as a fuzzy blur. Trying to image it is a challenge as the object is large and the swirls and dust lanes are quite feint.

On the 14th September the sky was perfectly clear and I now have the leads for my camera to run dslr shutter. This means that I can set up the telescope, track my target and take multiple timed exposures with the camera. I decided to take about 100 x 30 second exposures of the Andromeda Galaxy. I set up the equipment and then left it to take the photos automatically controlled by my laptop. I set the format this time for RAW in the hope that I might get a better resolution than the normal JPG format.

Well, all kinds of things started to go wrong....clouds...battery went down in the camera...tracking motor stopped. In the end I managed about 70 exposures and then stacked them in Deepskystacker.

The result above is after hours of processing and stacking.

I have the images in FIT format as well and i'm sure the results will be super in a suitable FITs processor, but I can't seem to get one working! Still, something to play with later perhaps!

M81 and M82



These are known as 'Bodes Galaxy' and the 'Cigar Galaxy' they are in the constellation of Ursa Major. I have seen them before with my Skywatcher 130 reflector, but not easy to find.

On Tuesday the night sky was wonderful, so I set up the ST80 and SLS computerised mount to point at Ursa Major and try to image M81, M82, Whirlpool Galaxy and Pinwheel Galaxy.

Again, the SLT mount along with 'Starry Night' was superb! I managed to image all of these with the Canon 350D. The Pinwheel Galaxy and the Whirlpool Galaxy was a bit feint and needed more and maybe longer exposures, but i'm so pleased that I captured them!

I now need a lead for dslr shutter so that I can leave the computer to take continuous images for an hour without intervention.

G4AQB Astro Wiki

Today I went to W.H. Smith to get a copy of this months Sky at Night Magazine. Guess what?
On page 75 under 'Super Sites' my Astro Wiki Site is listed with a screen capture of my site!
I'm really pleased, especially when I checked the traffic to the site. (Fame at last!) I wonder if Patrick Moore or Chris Lintott has looked at my sites? Click HERE for my Astro Wiki.
OK...what is a WIKI?
Well, you can add and edit pages on a WIKI (WIKIPEDIA) Quite a powerful medium for adding and building up information on a particular subject although there are a lot of sceptics as I found out when I posted on SPA!
I did know earlier when Sarah Reed from S@N sent me an e mail but I wasn't sure which month of the magazine it would be in.

M52 Scorpion Cluster and M103



M103 (top) and M52 (lower)
Here are a couple more images taken on 7th August. Again, widefield views with the Canon 350D and ST80.

There is a nice piece of software called DSLR Shutter which allows the camera to take multiple exposures of any length. Problem is...it appears to work from an RS232 port which my laptop has not got. I'm trying to find a way of using a USB port, but if i'm also controlling the scope and i'm not sure if another USB - RS232 converter will work.

Well, Summer continues to be anything but! Now we have winds from the North, clouds and cool...and I mean COOL. Last weekend it rained non-stop...and i'm getting a bit fed up!

Bank Holiday Weekend coming up, you know what Bank Holiday weather is like!

I wonder if for once it could be nice?
