Following on from our last post which featured a couple of conjunction images from the middle of March, we’ve been out snapping again to capture the conjunction with the new crescent Moon!

Shot with a Canon Eos 550D and a 50mm lens at f/2.8 ISO100 on a 3 sec exposure - Venus, Jupiter and the Moon on 24th March 2012 (click to enlarge) Credit: Sky-Watching/A.Welbourn

The photograph above was taken on Saturday 24th March. Venus shines at the top of the image above Jupiter with three of its moons visible.

The crescent Moon glows faintly with earthshine, where light reflected from the Earth helps show features usually lost in the shadow.

This time a 4 second exposure, f/3.5 ISO100 - More of the Moon is lit by the Sun as it shines next to Venus (Jupiter is below the cloud) from 26th March 2012 (click to enlarge) Credit: Sky-Watching/A.Welbourn

The image above was taken two days after the first photo on Monday 26th March, and you can see how much more of the waxing crescent Moon is lit.  Some of Jupiter’s moons are also visible again (at full size).

This evening the Moon sits between the Hyades and Pleiades clusters (see our Monthly Guide for details) and if it stays clear we’ll be out there again trying to get more shots.

Who could ever get bored of imaging the night sky?!

Clear skies all :)

Jupiter and Venus conjunction images

There has been a fair amount of coverage in the media recently about the conjunction between Jupiter and Venus. Typically when they appeared closest (on 13th March) the clouds settled in firmly overhead and refused to move.

Thankfully yesterday and this evening it has been relatively clear by comparison! A little bit of haze failed to ruin the opportunities for some photos, so here are a few from over the last two evenings.

The image above, taken on Wednesday 14th March shows the bright Venus above Jupiter (with a few of its moons).

Venus will gradually move up and past the top of Jupiter over the next two weeks.

The image above was taken one day later on Thursday 15th March, and you can see how Venus has moved in relation to Jupiter. In this image now only one moon of Jupiter (Callisto) is visible next to the planet.

There are many more photo opportunities involving Jupiter and Venus this month, check our monthly guide for details (click to enlarge) - Credit: Sky-Watching/A.Welbourn

We can’t be sure the weather will continue to be kind, but should it be generous we’ll try and get some more interesting photos! Perhaps if the haze lifts we’ll even be able to get our telescopes out again!

Now I’ve gone and jinxed it…

Clear skies :)

I’ve a feeling we’re not in Kansas any more…

NASA has today released a remarkable image taken from the Mars Reconnaissance Orbiter using the High Resolution Imaging Science Experiment (HiRISE) camera.

HiRISE captured the image on 16th February this year (as the orbiter passed over the Amazonis Planitia region of northern Mars) and it clearly shows a whirlwind creating a twisting column of dust more than half a mile (800 meters) high!

A dust devil imaged on another world! Excellent! :)

The MRO has been examining Mars with six science instruments since 2006, a mission that has returned more data about “the red planet” than all other orbital and surface missions combined.

There are more than 21,700 images taken by HiRISE which are available on the instrument team’s website, which you can visit and peruse by clicking here.

And you can read more on the JPL website here.

Astrophotographers capturing the heavens

March 7, 2012

Space pics are cool, no argument from us there. Since we started this blog we’ve brought you enough images to fill a photo album (and have slipped in quite a few of our own along the way).

A lot of people think you need in depth knowledge or mega expensive gear to take astro photos, but from our time spent in the “twitterverse” we’ve learnt that not only are there thousands of enthusiasts eager to get stuck in, but a multitude of talented people who do extraordinary things with a range of equipment!

The Moon

The first point of call for most night sky snappers is our beautiful Moon. We first started imaging the Moon using handhelds and camera phones (held up to the eyepiece of the telescope), but there are a variety of ways to get great images!

If you don’t have a telescope, a DSLR can capture superb images all on its own. Twitter user CJ5ive used a Nikon D200 to grab this shot, and it looks great! Having a sturdy tripod helps remove any camera shake caused by the shutter opening, and with good seeing conditions you can get crystal clear shots.

Don’t have a DSLR but have a telescope? With a steady hand Phil Hammond took this great example of afocal photography, using an iPhone 4s and a Sky-Watcher Evostar 102 Telescope. It can take a little patience to get it lined up, but you can get some great close up images.

Using a CCD camera you can capture superb detail, as demonstrated in this image of the Clavius crater (click to enlarge) - Credit: Paul Wharton

Want to get even closer? By using a CCD Camera (like a webcam) you can record video of your target and then stack the individual frames to bring out the details. Paul Wharton provided us with this great close-up of the Clavius crater on the Moon, taken using a Sky-Watcher 200P Telescope and a Trust webcam from eBay bought for 99p!

The Planets

Getting a close up look at the planets through a telescope can be awe inspiring, so imaging them can be very rewarding.

Using a webcam attached to a telescope you can get great images like this great view of Jupiter (click to enlarge) - Credit: John Mason

Jupiter is always a good target as through a telescope you can see clear details. John Mason‘s image shows Jupiter as a beautiful marble in space, captured using a Nexstar 6SE SCT Telescope and a SPC800 webcam (compiled using the stacking software Registax).

Getting even closer to Jupiter this shot from Paul Wharton shows the different bands, the famous spot and two of Jupiter’s moons. You can even make out the shadow of a moon transiting the disc of the planet! This fantastic image was captured using a Sky-Watcher 200P Telescope and a Philips webcam.

Saturn is another must see through a telescope, and Jamey imaged it incredibly clearly (click to enlarge) - Credit: Jamey Erickson

There’s also nothing like the feeling of viewing the rings of Saturn with your own eyes. Very little compares to seeing it live (as it were) but the picture produced by Jamey Erickson comes awfully close! Created by stacking 40 light frames (with no dark frames) using a Celestron CGE-1100 SCT Telescope, a Canon 5D Mk II remote via MacBook Air, all guided with an iPad via SkySafariPro. That’s quite a setup!

Stars and a Nebula

Most of the time clouds are an astrophotographer’s nemesis, but they can help provide great atmosphere to a photo of the stars.

Cloud movement in a long exposure shot can create a beautiful ethereal feel when in front of a clear star filled background (click to enlarge) - Credit: John Mason

Orion is one of the most easily recognisable constellations in the night sky, and John Mason took this great shot of it framed by clouds using a Canon 1000D at 18mm on a 7 second exposure.

A similar shot of the fantastic Orion, with added International Space Station goodness (click to enlarge) - Credit: Sarah (purpleface)

The ISS frequently passes over the UK, an example of such a pass can be seen in Sarah’s image featuring Orion and the Hyades cluster above. Taken using a Canon 7D with the 18-55mm kit lens, 15 second exposure at ISO 400 (f/3.5). It also helps demonstrate just how far the space station travels across the sky in 15 seconds when moving at around 17,500mph.

It’s about 73 miles, the equivalent driving distance from Peckham in London to Dover by the English Channel!

Using a good zoom lens you can clearly capture the dusty shape of the Orion Nebula (click to enlarge) - Credit: Sarah (purpleface)

Using the same camera but this time a 90-300mm lens, Sarah’s shot of the Orion Nebula shows clear definition of its familiar shape, taken at an exposure time of 3.2 seconds, ISO 5000 (f/5.6).

Stacked shots taken via a telescope can provide far more detail than a single exposure alone, as this fantastic image demonstrates (click to enlarge) - Credit: Jamey Erickson

This jawdropping picture of the Orion Nebula from Jamey is the result of stacking 50 light frames and 50 dark frames (with the same equipment as his Saturn image above). Both images were stacked in Nebulosity and processed in PixInsight.

Astronomy Events – March 2012

February 29, 2012

by yaska77

February saw some nice astronomical activity, but what can we look forward to in March? Evenings are slowly getting warmer while remaining nicely dark, so here are some upcoming astronomy events for the next month to keep you looking skyward!

Thursday 1st March - First Quarter Moon

Saturday 3rd March – Mars is at opposition in the constellation Leo. This means it’s in an opposite position in the sky to our Sun so will rise at sunset and set at sunrise

Monday 5th March – Mars is at its closest to the Earth today (image below), and Mercury is at greatest Eastern elongation meaning it’s at its furthest from the Sun. It should be visible in the west (under favourable conditions) for the first 2 weeks of the month just after sunset

Mars is at its closest to the Earth today (this time around!), and can be found in the constellation Leo as shown at 21:00 GMT (click to enlarge) - Credit: Sky-Watching.co.uk/Stellarium

Thursday 8th March – Full Moon, sometimes known as the Worm Moon

Saturday 10th March - The Moon is at Perigee (362,400 km), the closest point of its orbit this month

Tuesday 13th March – Tonight the two planets Venus and Jupiter appear only 3° apart in the night sky. Although they will be closest tonight, the distance between them will only increase slightly over the next few evenings

Thursday 15th March – Last Quarter Moon, plus the Jupiter and Venus conjunction continues in the western sky after sunset

Tuesday 20th March – Spring Equinox in the Northern Hemisphere

Wednesday 21st March – The planet Mercury is in Inferior Conjunction (closest to the Sun) so it will be too bright to be visible

Thursday 22nd March – New Moon which doesn’t rise until the Sun comes up, so with it out of the way it’s a good night to view some deep sky objects

Jupiter, Venus and the Moon in alignment from 23rd February 2012

Saturday 24th March – The planet Uranus is in conjunction with the Sun; and Venus, Jupiter, the Moon and Mercury are aligned at sunset (in a switch around from the above), although Mercury will be lost in the glare from the Sun

Sunday 25th March – British Summer Time (BST) begins in the UK and clocks go forward one hour from 01:00 GMT to 02:00 BST. Following on from yesterday evening’s alignment, the Moon will appear to the right of Venus this evening, closer than they appeared on 26th January (as below)

Monday 26th March - Moon is at Apogee (405,780 km) the furthest point of its orbit from the Earth

Tuesday 27th March – Venus is at greatest Eastern elongation, and takes part in a great night sky display this evening. The Moon sits between the Hyades (in Taurus) and Pleiades star clusters, just above Venus and the setting Jupiter

A great target for those with a DSLR camera, why not tweet us any images you get? Shown at 21:00 BST (click to enlarge) - Credit: Sky-Watching/Stellarium

Friday 30th March - First Quarter Moon

Planets visible this month:

Mercury
Venus
Mars
Jupiter
Saturn
Uranus

Remember, it can take your eyes up to 20 minutes to become properly dark adapted, and anything up to an hour for a telescope to reach ambient temperature outside (to ensure the best image), so give yourself plenty of time to get set up!

To make it easier to find this list of astronomical happenings you can also locate it in the “Monthly Guide” section in the menu bar to the right. Handy! :)
