Before you consider buying expensive equipment for viewing the wonders of the night sky, binoculars are one piece of equipment every amateur astronomer should have.
Many beginners to astronomy (especially around the holiday period) are sometimes dead-set on getting a telescope, but many aren’t aware that a good pair of binoculars can outperform many entry level telescopes for a similar cost, or much less.
Binoculars are simplicity in themselves — maintenance free, instantly available for use and very versatile, as they can be used for daytime, or “terrestrial viewing” just as well. It is difficult to say the same for with most telescopes.
Go into any photographic store, or website that sells binoculars and you will be met with literally hundreds of different makes, types and sizes – confusing for the beginner, but with a few pointers it can be easy to choose. (more…)
Do you have a new telescope, or are you considering buying a new one? Hopefully, you have chosen a telescope with the best specifications for your budget, but before you can truly get the best out of your wonderful new window on the cosmos, you need to have something even more important than the scope – Eyepieces!
A lot of people new to astronomy, or new to buying astronomy equipment tend to concentrate on telescopes and unfortunately overlook eyepieces, settling for the basic set of 2 or 3 that come with the new telescope.
Eyepieces are probably the most important part of your observing equipment, as they are at the heart of your setup and can make your observing experience fantastic or disastrous, or make an average telescope great or an excellent telescope bad. (more…)
If you ask someone to describe or draw a telescope, nine times out of ten it will be a refractor.
The refractor telescope is quite possibly the most common or easily recognized telescope. It is a very simple design, which has been around for hundreds of years.
The history of the refractor is that it was first invented in the Netherlands in 1608, and is credited to 3 individuals; Hans Lippershey, Zacharias Janssen – spectacle-makers and Jacob Metius.
A blog for us AMATEUR amateur astronomers. By @RadioVicky.
I’m 33, I live in Bristol and I like astronomy. However, I don’t have a telescope and even if you did give me one, I’d be uncertain where to put my eye. I write comedy and I’m a professional blogger. My favourite colours are beer and dark skies.
Telescopes scare me. Not in the way a stranger in my bedroom or a spider in my knickers would scare me, but they do fill me with a certain fear.
I mean, I absolutely love things that go *shine* in the night, and have since I was a little girl, but the prospect of going out and buying a scope – something I know NOTHING about — is fairly petrifying. It even makes me feel a bit of a fraud. How can I be in to astronomy when I don’t even know my azimuth from my elbow? And also, I’m not too hot on my constellations either – sure, I know the main ones they teach you at school, but ask me to point out Lyra? Pegasus? Lucky Jim’s Pirate Ship?
OK, I admit it, I’m an AMATEUR amateur astronomer, but so is 99.9999999999999999999999% (possibly more nines than that, I didn’t have time to conduct a survey) of the world’s population, so it’s a cool club to be in.
Before I got friendly with astronomers on Twitter, I always fancied one of those thin tubular ones they sell for £90 in Argos. Surely I would be able to see the storms on Jupiter, the arms of Andromeda, and the Bristol football team practicing from 10 miles away? Turns out I’d be better off peering through a toilet roll tube with some cling film on the end of it – I’ve been told that cheap telescopes merely turn unimpressive white dots into marginally less impressive WOBBLY white dots, so I’m saving the cash for a Virgin Galactic space holiday instead. I hear the weather’s quite exceptional on Mercury…
But something happened this weekend that made me feel better about scope envy. I’ve been getting friendly with our very own @virtualastro on Twitter, and when I discovered I had 900 free minutes to use before the end of the month, I thought it was nigh on time we spoke to each other.
So, I called him up, and we spent a total of FIVE HOURS on the phone over the course of Saturday and Sunday night. Rest assured Twitter, we have plotted and planned some very exciting things together which will be blazing your way like a comet made of ideas instead of muddy ice soon …but the best, most wonderful, amazing, magical thing we did was…GO STAR HOPPING TOGETHER. Without a freakin’ telescope!
Even though we are about 70 miles apart (I live in Bristol, he lives in Oxfordish somewhere) we were both able to look up at the same sky, see the same ISS passes, and the same meteors. It was remarkable to be on the phone to someone with such an incredible knowledge of the skies. I sat gob smacked, mouth and ears open, as he talked me through constellations, clusters, satellites and gory Greek myths. I had no idea Cassiopeia had been a naughty girl and was sentenced to dangle upside down on a chair for eternity. I’d never heard of the Cygnus Rift — an ominously dark patch of sky in our milky way. I couldn’t even pick out the summer triangle, but now I know where it lives I will undoubtedly point it out to people in the pub, spilling cider as I leap around, trying to remember which stars make it up.
The best part was a dazzling ISS pass with a Perseid meteor streaking past like an arrow through a love heart. @VirtualAstro even had to put the phone down to deal with the deluge of tweets, and it felt amazing to be part of something so communal, so magical, yet so fleeting.
He also reassured me I didn’t need a telescope to enjoy the skies – which is fabulous because I was getting a bit sick of wishing for one on every meteor I saw. He said ‘if you look up at the sky…then you’re already an astronomer,’ a line which neatly castrated the last traces of my scope envy.
As I lay back and looked at the star-flecked sky, with crickets singing in the hedge, fired up with a guided tour of our resplendent heavens, it dawned on me. This was better than any naughty phone chat line. He could quite easily wire up a premium-rate number to his phone and charge £1.50 a minute for the pleasure of his knowledge.
Yep, I had a great time star-gazing without a scope last night. To the point of rubbing my thighs and drooling a bit. And how was it for you, darling?
Vicky pretended she was having fun looking through the telescope, but the view was better with just her eyes.

What is it? – The International Space Station or ISS is a large spacecraft which orbits around Earth. This orbit allows the ISS to be reached by launch vehicles (such as the Space Shuttle) of all the international partners for the delivery of crews and supplies. It is the largest and most complex international scientific project in history. The ISS is the size of a football pitch fitted with almost an acre of solar panels that provide electrical power to six state-of-the-art laboratories.
Can the ISS be seen from Earth? – Yes, it travels at an amazing 17,000 mph and orbits earth at an altitude of approximately 250 miles. The sheer size of the structure and array of solar panels reflect sunlight, making it the biggest, brightest object orbiting earth. Only the sun and moon are brighter. It can easily be seen moving across the night sky, at certain times, almost resembling a slow moving fireball.
How do you capture it on camera? – With a bit of planning and the right equipment it can easily be captured on camera:-
Planning – Firstly, one needs to calculate at what time the ISS will pass over the skies above. This can easily be found by visiting a website: www.heavens-above.com which will identify the exact days and times at when the ISS will pass directly above one’s location, and which part of the sky to look. There are also a number of excellent mobile applications such as ‘GoSatWatch’ and ‘Flyby’ which allow this to be done remotely.

Execution – A good ISS capture will require a long exposure. A tripod is therefore required to keep the camera nice and steady. A wide angle lens will ensure maximising as much of the ISS flyby which can travel across the entire horizon. Personally, I use the Olympus 7-14mm or 8mm fisheye which are ideal lenses. Try to locate a foreground object of interest within the frame, a line of trees or buildings in order to give the image perspective and scale. Set the camera to manual and use long exposure times of anything between 15 and 30 seconds. With camera primed and in position all that is left now is to wait for the ISS to enter the field of view. By capturing a single or number of continuous exposures the resulting image(s) will reveal a long trail across the frame. Capturing numerous and continuous images will allow you to stack and produce a composite, which can produce stunning results.
ISS Double flyby photo (bottom) – For this ISS double flyby image I chose a location that offered a good foreground subject (water) and scope to cover the entire east/west horizon. Planning involved choosing an evening where the ISS would fly over my location numerous times (in one night) and a look at the weather forecast to ensure clear skies. Armed with a one man tent and all my camera gear I headed off and arrived on site late evening on June 11th. The first ISS pass was due at 2300hrs and subsequent passes every 90 mins. The plan was twofold 1) Set up one camera waterside and take continuous 15sec exposures for the entire night 2) Use a second camera for each ISS pass in different locations at the site. In between passes I would grab a short power nap huddled in the tent. Not a very comfortable evening but the resulting images made up for it. Using stacking software I produced two composite images, one detailing the ISS passes alone and the other including a star trail from the entire evening.
The star trails and bright light (moon) is the resulting visible effect of earth’s rotation. The location choice was also perfect as the morning mist makes for an eerie scene, perfectly complementing the ISS pass. The images made the national press the following day, which was very pleasing. One final word about capturing the ISS – it is due to be decommissioned (crashed into the sea) in 2020, so be quick!
