First Type Welcome to another new edition of Look Up! We’ve been away for awhile but in some ways it’s like we never left. Our sister publication the AstroSouth Directory has carried the flag until we were ready to return bigger, bolder and stronger than before. Talking of bolder – Barack Obama’s decision to commercialise space heralds a great boost for the UK space industry in general. (Early aviation contracts meant that the US post could be flown by small aviation companies, which also carried passengers; a few then went on to become some of today’s worldclass airlines).

Astrophotography - March 2009 @ IOW Star Party - Picture ©Graham Green 2009

His hope is that this move will do the same for the micro-satellite and space tourism industry. With the space shuttle completing its final missions any time soon, new solutions need to be found and I believe Great Britain has yet another chance to become “great” again. It’s an opportunity we cannot afford to miss. Enjoy the read. David Woods: Editor

This month’s top five - Messier Objects M42 - The Orion Nebula As Winter passes the baton to Spring we begin to lose the glories of the dark Winter sky. If you managed to do some observing over the Winter months then aren’t you the lucky one! The weather has been dreadful; there has been the odd break in the weather here and there but it isn’t always at a convenient time and when there is a break and a chance to grab your binoculars or set up your telescope, the cloud always seems to roll in the moment observing begins! Talking of cloud, there is plenty of it in interstellar space in the form of gravitationally-bound blobs of cold, neutral hydrogen intermixed with traces of other elements. The constellation Orion lies to the South West in the mid evening sky this month and contains plenty of gas and dust known as the Orion Molecular Cloud Complex. Barnard’s Loop, the Horsehead Nebula, M43, M78 and the Flame Nebula are all related, but the most famous and easy-to-see object there is M42 which is located below Orion’s belt in the region known as the sword. The sword comprises three stars in a dark, light pollution-free sky the stars appear to look a little misty. Through a pair of binoculars

Look Up! March 2010

this misty patch begins to look more structured; the brighter part looks fan shaped but with a closer look the nebula appears quite spherical. This area is rich in young hot stars that help to illuminate M42 with their infrared and ultraviolet radiation. These stars form the Trapezium open star cluster and lie at an estimated distance of 1,800 light years. In 1993 the Hubble Space Telescope first observed M42 and ever since then M42 has been a regular target for the HST. This region hosts around 700 stars at various stages of evolution. The birth of stars and their Protoplanetary disks have been studied in detail and help to form theories on the formation of our own solar system and studies on the most massive stars that emit destructive high levels of ultraviolet energy. This is a large ‘bright’ object of 4th magnitude that extends across a 10° region of the sky; it is an easy object to find and view with a pair of 10 x 50 binoculars or small telescope with low magnification.

Point your telescope at this month’s targets...

M38, 36 and 37 There are three easy to find Messier objects to view in the constellation of Auriga. This, like Orion, is a Winter constellation but it is still high enough in the south-western sky to be seen and has three open star clusters that can be found easily with a pair of binoculars or a small telescope. If you locate Orion and look north you will come to the bright star Capella in the constellation of Auriga. Imagine a line a third of the way from Capella to Betelgeuse in Orion and you will find the first of the open clusters, M38. Like the stars that have been formed in the Orion Nebula, all other open star clusters were formed from a ‘giant molecular cloud’; the stars within them are loosely gravitationally bound to each other. M38’s brighter stars lie in a pattern resembling the Greek letter “Pi” (see if you can locate it). It lies at a distance of 3,420 light-years and was formed about 220 million years ago. It has an apparent magnitude of 7.4.

M37


Image: 2MASS

Follow the imaginary line a little further and you will come to M36 and then M37. M36 is at a distance of about 4,100 light years away. This cluster has attracted some attention as the most likely origin of a massive OB star that exploded about 40,000 years ago; creating the supernova remnant Simeis 147, there is an on going search for planet-building stars within M36. The Spitzer space telescope will also be investigating it. This cluster is at a key stage in terrestrial planet formation and the survey will likely detect infrared excess emission from debris disks and transition disks. M37 is by far the most stellar populated cluster out of the three; there are at least 150 stars in this cluster. M37 has been around for about 300 million years, it is 20 to 25 light years across at a distance of 3,600 light years and hosts at least a dozen red giant stars. In the surrounding star field of around 12arcmin x 12arcmin there are up to 2,180 stars, a number of which are white dwarfs; a total of 24 variable stars have been identified too. Star clusters such as M37 are valuable in the study of stellar evolution. M37 has been studied as a part of the RACEOC project Rotation and ACtivity Evolution in Open Clusters) which is aimed at exploring the evolution of rotation and magnetic activity in the late-type star* members of open clusters of different ages.

These three objects look just great through binoculars but if you can use the power of a telescope the stars in M37 will be visually rewarding! *A star of spectral type K, M, S, or C with a surface temperature lower than that of the Sun. The term dates from when astronomers thought that all cooler, redder stars like these were at a later stage of evolution than the hot blue, white and yellow-white stars of spectral types O, B, A, and F which were said to be called earlytype.

M13 the Great Hercules Cluster

This isn’t a Spring sky object is it?” you may be thinking, but it is I tell you. Each season we get a chance to glimpse six months ahead if we are prepared to observe after midnight. This has the advantage of us not only being able to view the constellations six months earlier but, if you live in an urban area, at this time of night a lot of domestic lighting has been switched off thus reducing nuisance light pollution.

Not all the stars that make up this fine globular cluster belong to it, however; there is one star - Barnard Number 29 – a young, blue, type B2 star that has ‘hitched a ride’ during M13’s journey around our galaxy.

High in the south-eastern sky is the constellation of Hercules - look for the famous “Keystone” asterism. If you are using binoculars, take a look at the righthand side at about a third of the way down and you will be ‘grabbed’ by the view of a 5.8 magnitude fuzzy patch of light.

Global Positioning Satellites are a real boon, especially if you move around a lot. If you own a Meade Telescope with an AutoStar handset controller then I guess you do too. But, every time you switch it on, it asks for date - OK.Time, check, lat and long of your location -Umm... Unless you researched your site(s) and found this info on the Internet, then the accuracy of your scanning of the heavens will be a bit frustrating when you start observing or imaging and objects start tracking out of your eyepiece. Now there is an answer.

Just not quite so posh. And with only to wind up being captured in that telescope you can take just as your camera. Then, as you get better, amazing pictures. Well, not quite so the amazement keeps on growing as your images become clearer, brighter and more ‘Wow’ worthy. Hubble, at a very basic level is a (rather larger) Newtonian Reflector with some cameras on it that are admittedly somewhat out of the range of an amateur astronomer’s budget. But who cares about that? If you have a digital SLR or a webcam, then there is nothing stopping you hooking it up to your telescope, pointing it at whatever you choose and capturing some images. That, in a nutshell, is what the HST does. Before we get into the nitty gritty of the different types of telescopes we can use for our astrophotography, I’ll be mentioning ‘focal ratio’ in each description. This is basically how fast a telescope is. Or, to put it another way, how much light it gathers for its focal length and aperture. The lower the number, the faster it is - i.e. an f4 scope gathers more light than an f12 scope….and another thing to remember is that the higher this ‘f ’ number is, the more ‘contrasty’ your image will be, which is great for planets and the moon.

That’s not too much of speed of your refractor (decrease the observations are generally below an issue as all types of telescope can focal ratio) by using a focal reducer what you would hope and the use take a peek at pretty much anything which essentially halves your scope’s of high magnification eyepieces (EPs) in the sky. Some things they can see ‘f ’ number. This pretty much doubles the field of view (FOV) and gives you more light to play with. But because your FOV has doubled, your object is half the size it was. Hmm, another compromise. Or, you can ‘slow down’ your Newt by employing high magnification EPs and Barlow lenses to effectively increase the focal ratio – turn it into a f10 scope instead of f5, for example. This additional magnification dramatically cuts the amount of light entering the eyepiece or camera resulting in a dimmer, but more contrasty image of the planet you are observing. You see, if you have an interest in everything in the sky or you are just starting out in astronomy or astrophotography, you may not have decided what, if anything, you’d like Bigger Telescopes can perform better like Martin’s Meade LXD75 SN-10, but take time to set up, cool-down and are not very ‘portable’.

every telescope will be some form of compromise and no scope will do everything really well. But, there are ways to make this compromise easy to handle! All this information, and we’ve not even got a camera on the scope yet! Sorry, lots to get across first. The Best Telescope As far as your garden Hubble is concerned, bigger is not always better. ‘The best telescope’, somebody once said, ‘is the one you use most often’. And those are superb words of wisdom from somebody who may well have suffered from aperture fever. What is aperture fever? Basically,

DSLRs like the ubiquitous Canon EOS 350D do a great job of capturing images when connected to a small telescope. With a motorised mount, long exposures catches when they want to buy can be achieved.

The question that often arises on most Forums is, how does one go about getting one started? HantsAstro has a growing reputation for organising and taking part in various events across the South of England. The success of our Telescope Amnesties and the recent MoonFests (which we are expanding on for this season by the way) initiated a steep learning curve but we have gained invaluable experience.

The night sky this month by Graham Green

March Sky The Planets Mercury will be unobservable until later this month. On the 14th the planet passes through superior conjunction. As we approach the end of the month you’ll be able to see Mercury after the Sun has set low down in the western sky. On the 26th Mercury lies below and to the right of Venus and then on the 29th Mercury and Venus are in conjunction. Venus – as March progresses, Venus pulls away from the Sun and once again becomes visible in the western evening twilight sky. In addition to its encounters with Mercury, Venus sits below the crescent Moon on the 17th. Mars is high in the sky throughout this month from evening until the early hours of the morning as it sinks down westward in the constellation of Cancer. The planet has been moving retrograde but on the 11th it becomes stationary before it once again moves against the backdrop
