National Geographic Star Planetarium

On my travels around the internet I found the National Geographic Star Planetarium. This planetarium can transform a room into a space theatre. A Cyber Sky CD-ROM comes with it and is packed with facts and ancient legends to learn about as you watch projected stars move across the ceiling.

I think this kind of childrens planetarium has been around for many years now and has been updated in it’s look and now comes with a CD where it used to come with a cassette tape (remember those?).

“Transform your room into a 360-degree planetarium filled with stars and constellations. Includes a CD audio tour of the night sky and a hand-held meteor maker to add streaking meteors on command. Use the constellation dome outdoors as a 3D glow-in-the-dark star map. With lights, sounds and fascinating facts, it’s just like being in a real planetarium at home!
Age 8+”.

A great gift for the junior astronomer and not too expensive either, I found a similar Star Theatre which looks an improved version at The Science Museum for £29.99, or the version pictured above from The Toy Shop at £19.95

UK Astronomy Buy & Sell

A short while ago I discovered the UK Astronomy Buy & Sell website. It was nice to find a website where you could list any astronomy item for sale for free, instead of having to pay the high listing and final auction fees of eBay.

A couple of weeks ago I listed an LX200 data cable, and some astronomy books for sale, a couple of the books sold and the communication between the buyer and myself was easy via email and the transaction was easy, payment was made through PayPal, so eBay (who own PayPal) still got some commission!

This week I have now also become a buyer from the site, as I purchased a Baader UV/IR Rejection Filter for £16.50 including delivery and it turned up in the post today, again a nice straight forward transaction.

Admittedly I do frequently look at eBay for astronomy listings, but I also regularly visit the UK Astronomy Buy & Sell Website, if you don’t know it have a look yourself, you may find a bargain!

Comet Holmes 17P Update

I have not been out for a couple of weeks, it seems the colder weather has put me off and I have been very busy in the evenings as well. But I managed to get outside for a couple of hours the other night after wrapping up warm. I went looking for Comet Tuttle but could not really see it or Autostar was pointing me in the wrong direction.

Anyway, I managed to have a re-visit to Comet Holmes, to see what has happened since I last looked at it about 14 days ago here. It appears that the outer dense ring has decreased or should I say thinned out.

This image was taken by my telescope mounted Canon 300mm lens.

Using a Palm with the LX200

I was amazed to find a program called Planetarium which can be installed on a Palm top with Palm OS 3.5 and above. Planetarium is a full astronomy program which can also control your telescope.

So the first thing I did was go and get my old Palm M505 out of the loft and charge it up. The Palm is something I have not used for ages as I kept finding the battery was always out of charge whenever I went to use it. Another thing is that nowadays the mobile phone can do most of things that the Palm can, but now it has a new lease of life as long as I can get it to talk to the LX200.

I then downloaded the Planetarium software and installed the extra LX200 drivers. Installation was easy, after I tried to install the latest Palm Desktop software onto my Vista PC, which was not too happy, so I ended up installing it instead onto my XP laptop which worked.

After starting Planetarium I entered the latitude and longitude co-ordinates and the date and time. Overall the software looks good, you can even set the read out to display in night mode where the screen turns red.

The next thing I need to do to is now find a Palm to RS232 Serial cable so that I can try and connect the Palm to the LX200 somehow. If anybody has any ideas on how to get the Palm to talk to the LX200 then please leave your comments.

Solar System Mobile Kit

I saw this Solar System mobile kit on the web. It’s a mobile of the solar system that comes in kit form and has to be put together.

The solar system mobile kit comes with everything you need including paints, brushes and a full colour poster.

What a great idea for a kids present though, something for them to do and educational at the same time and something for them to hang in the bedroom afterwards. A good introduction to the solar system for budding junior astronomers.

“Create the entire solar system in your own home. This fascinating kit has everything for making a beautiful, glow-in-the-dark mobile featuring all our known planets. 75cm high, 75cm wide when complete. Includes a bonus wall chart full of fascinating facts. Ideal for supporting Key Stage 3 of the National Curriculum. Age 7+”.

The Solar System mobile is available here from The Science Museum for £16.99

The Monthly Sky Guide Book Review

The Monthly Sky Guide 7th Edition by Cambridge University Press (ISBN 0521684358)

The Monthly Sky Guide contains a chapter on the main sights visible in each month of the year in the northern hemisphere.

The Monthly Sky Guide was first published in 1987 and it gets updated every few years, this 7th edition of The Monthly Sky Guide has details on planet positions and eclipses up to 2011.

At around 65 pages this book is not the largest astronomy book ever seen but it does contain a lot of useful information. The beginning of the book contains a useful introduction which answers questions such as what is a Star. What is a Constellation? How bright are the stars? etc. It also helps you to find your way around the night sky and describes how the night sky changes through the seasons.

Each month in turn provides you with a night sky map and details on key stars for the month, what the planets are up to together with any meteor showers or eclipses that are due that month. A particular constellation is then looked into in more detail, describing what to look for in that constellation.

Overall the maps are really useful and easy to read, The Monthly Sky Guide is an excellent book for anyone who wants to learn about the night sky and the constellations and know what major events are coming up in the next few years.

Monthly Sky Guide is available at Waterstones

The Sky at Night – Grand Collision

Sir Patrick Moore looks ahead to 2 billion years when the Milky Way will collide with another galaxy, Andromeda, an event which will destroy stars and planets but will eventually create new stars, solar systems and planets.

Dr Chris Lintott steps outside to look at Andromeda, easily visible in the night sky using binoculars. It is still 2.5 million light years away, but getting closer by the day.

Moon In My Room

I found “moon in my room” whilst surfing around I am really tempted to buy it, ok so it’s bit of a toy, but the idea is really great, and it looks good too.

Moon In My Room – What could be cooler than having your own moon hanging up on your bedroom wall or ceiling? This fasinating moon with authentic detail shines just like the real moon in the twelve different lunar phases.

Using a mini remote control, you can smoothly glide through the twelve phases of the moon, or leave it on automatic and watch it glow from Waning Crescent to Waxing Gibbous and finally the New Moon. The light will automatically turn itself on in a darkened room, and off after 30 minutes; ideal for night-time wind-down, although it can be manually over-ridden.

Moon In My Room is really easy to set up and no mains electrics are required. Just position the unit and use the wall mountings that are included in the box.

Moon In My Room also comes with an audio CD, explaining loads of exciting facts about the moon. Great for little astronauts.

Moon In My Room requires 4 AA and 2 AAA batteries. Diameter 26cm. For Ages 3+.

Moon In My Room features:

• Remote controlled moon with 12 light-up phases.
• You can control the Moon phases manually or leave it on automatic.
• A built in light sensor; it will automatically start illuminating in a darkened room.
• An auto shut-off mechanisum after 30 minutes of inactivity to save battery power. (Although you can override this feature if you wish)
• Audio CD
• Designed to be mounted on your bedroom wall via wall mountings.
• Size: 26 cm x 26 cm x 6 cm

The cheapest place I could find it was at Prezzybox for £24.95

Comet Holmes 17P

I was glad to go out last night on Halloween and see clear skies as I was after having a look at the Holmes Comet after it had managed to get so much news coverage and at the same time come away with some images of the comet which is currently in the Perseus Constellation.

The Holmes comet can be clearly seen with the naked eye in the north and it makes a good sight in a good pair of binoculars, even low powered telescopes will get a good view. Apparently the explosion of Holmes was so big that the comet brightened by a factor of a million.

Holmes is currently moving away from the Sun, and is almost midway between the orbits of Mars and Jupiter. When I looked through my LX200 10″ you could clearly make out a circular cloud of gas and dust emanating from the nucleus of the comet, together with a brighter cloud of material.

These images were not taken using a telescope but with my trusty Canon 400D SLR with a 300mm lens with the camera on top of my telescope, most images were at f/5.6 on ISO400 with exposures of around 30 seconds.

This second image of Comet Holmes below is a magnified image.

It is not clear what caused the comet to shed its skin, since it is moving away from the Sun’s energetic influence. One possibility is that the comet was hit by a meteoroid, or perhaps there has been a build-up of gas under part of the surface that catastrophically ruptured the surface.

Comet Holmes is a regular visitor to the inner Solar System. It takes 6.9 years to orbit the Sun once. It made its closest approach to our star last May, passing by at some 300 million km (190 million miles).
