It's already visible through binoculars but Comet ISON is set to get even brighter in the coming weeks.
So if you want to get a glimpse of the so-called 'Comet of the Century', here are a few pointers...
Comet ISON Viewing Guide
Make Sure You Have A Dark Sky And Clear Horizon (01 of06)
The most important requirements for successful comet viewing are complete darkness and a clear, unobstructed horizon. Darkness is absolutely essential if you plan to get a good view of the tail. You will need the kind of dark sky that you would find out in the open countryside, where you can look up and see a starry sky - Space.com
Where Will It Be In The Sky?(02 of06)
Looking south east at 6.30 am from the UK on 15 November.On 11 November the comet crossed the orbit of Venus, and by 20 November the comet will be so close to the Sun that it will be almost sunrise before its head clears the horizon, so viewing it at all at this time might be challenging, demanding crystal-clear skies. By the end of the month it should be easily seen in the eastern sky before dawn. We might just see the tail sticking up from beyond the horizon before the Sun comes up - armaghplanet.com (credit:Colin Johnston/Stellarium)
If It's Bright, The Naked Eye Should Do(03 of06)
For bright comets, the optical instruments of choice are just the naked eyes and, to a lesser extent, binoculars. When Comet ISON will put on its best display, throughout November and December, its coma will look like a tiny ball of light set within a milky glow. From the solid part of the comet, the tiny icy "nucleus" hidden within the coma, the tail (or tails!) will arc across several degrees of sky - NightSkyInfo.com
When Can I See It?(04 of06)
Comet ISON is roughly heading towards the centre of our Solar System. It will pass within 1.2 million miles of the Sun’s surface on 28th November when it reaches perihelion (the point when its at its closest to the Sun) before being whipped around to head back ‘roughly’ in the direction it came.Comet ISON's PathAs ISON makes its outbound journey, it will pass over the northern hemisphere of Earth at a distance of around 40,000,000 miles on 26th December. If ISON lives up to the hype, you could expect to see the Comet with the unaided eye anywhere between the middle of November until the middle of January 2014 (depending where you are on the planet) - cometison2013.co.uk
If You Do Want Some Equipment...(05 of06)
Binoculars make them more obvious, and they allow you to see subtle details in the tail – kinks, streamers, clumps and knots of cometary material – that the naked eye can’t pick up. And if you look at them through a more powerful telescope you can see sometimes subtle structure in and around the comet’s glowing head, too – jets, shells, and spikes… - waiting for ISON
If You Want Photograph ISON... (06 of06)
If you are using a camera and tripod, set your aperture to maximum, your manual focus to infinity and confirm focus is OK by taking a 30-second exposure of a star in the general area. Next take a one-minute exposure with a standard 50 mm lens at ISO 1600. Enlarge the image to look for the tell-tale small fuzzy patch which means you have caught a comet. Change to a longer lens (200 to 300 mm), zoom in and take several identical images of 30 seconds each - more photography tips here from Richard Higby
Comet ISON: Latest Pictures

This new view of Comet C/2012 S1 (ISON) was taken with the TRAPPIST national telescope at ESO's La Silla Observatory on the morning of Friday 15 November 2013. Comet ISON was first spotted in our skies in September 2012, and will make its closest approach to the Sun in late November 2013. (credit:ESO)

This graphic shows the expected location of the comet named C/2012 S1 (ISON) on Nov. 28, 2013. In late November and December of 2013, it could put on a show when heating from the sun could stir up a great deal of icy and dusty material. The comet is not a threat to Earth. At the time of its closest approach to Earth, on Dec. 26, 2013, comet ISON will come no closer than 40 million miles. When considering Earthly endeavors, that's not exactly a ringside seat.

Comet ISON on April 10, 2013(10 of18)

Comet Ison Roars Through Leo(11 of18)
In the early morning of Oct. 25 (6:45 a.m. EDT), NASA's Marshall Space Flight Center in Huntsville, Ala., used a 14" telescope to capture this image of Comet C/2012 S1 (ISON), which is brightening as it approaches the sun. The comet shines with a faint green color just to the left of center. The diagonal streak right of center was caused by the Italian SkyMed-2 satellite passing though the field of view. At magnitude 8.5, the comet is still too faint for the unaided eye or small binoculars, but it's an easy target in a small telescope.At this time of this image, ISON was located in the constellation of Leo the Lion, some 132 million miles from Earth and heading in toward the sun at 87,900 miles per hour.

NASA’s Hubble: Galaxies, Comets, and Stars! Oh My!(12 of18)
Approaching the sun, Comet ISON floats against a seemingly infinite backdrop of numerous galaxies and a handful of foreground stars. The icy visitor, with its long gossamer tail, appears to be swimming like a tadpole through a deep pond of celestial wonders. In reality, the comet is much, much closer. The nearest star to the sun is over 60,000 times farther away, and the nearest large galaxy to the Milky Way is over thirty billion times more distant. These vast dimensions are lost in this deep space Hubble exposure that visually combines our view of the universe from the very nearby to the extraordinarily far away. In this composite image, background stars and galaxies were separately photographed in red and yellow-green light. Because the comet moved between exposures relative to the background objects, its appearance was blurred. The blurred comet photo was replaced with a single, black-and-white exposure. The images were taken with the Wide Field Camera 3 on April 30, 2013. The Hubble Space Telescope is a project of international cooperation between NASA and the European Space Agency. NASA's Goddard Space Flight Center in Greenbelt, Md., manages the telescope. The Space Telescope Science Institute(STScI) in Baltimore, Md., conducts Hubble science operations. STScI is operated by the Association of Universities for Research in Astronomy Inc., in Washington, D.C. (credit:ASA, ESA, and the Hubble Heritage Team (STScI/AURA))
NASA's Hubble Sees Comet ISON Intact(13 of18)
A new image of the sunward plunging comet ISON suggests that the comet is intact despite some predictions that the fragile icy nucleus might disintegrate as the sun warms it. The comet will pass closest to the sun on Nov. 28.In this NASA Hubble Space Telescope image taken on Oct. 9, the comet's solid nucleus is unresolved because it is so small. If the nucleus broke apart then Hubble would have likely seen evidence for multiple fragments.Moreover, the coma or head surrounding the comet's nucleus is symmetric and smooth. This would probably not be the case if clusters of smaller fragments were flying along. A polar jet of dust first seen in Hubble images taken in April is no longer visible and may have turned off.This color composite image was assembled using two filters. The comet's coma appears cyan, a greenish-blue color due to gas, while the tail is reddish due to dust streaming off the nucleus. The tail forms as dust particles are pushed away from the nucleus by the pressure of sunlight. The comet was inside Mars’ orbit and 177 million miles from Earth when photographed. Comet ISON is predicted to make its closest approach to Earth on Dec. 26, at a distance of 39.9 million miles. (credit:NASA, ESA, and the Hubble Heritage Team (STScI/AURA))
Predicted Path for Comet ISON for Late November 2013(14 of18)

Comet ISON Passes Through Virgo(15 of18)
Comet ISON shines in this five-minute exposure taken at NASA's Marshall Space Flight Center on Nov. 8 at 5:40 a.m. EST. The image has a field of view of roughly 1.5 degrees by 1 degree and was captured using a color CCD camera attached to a 14" telescope located at Marshall. At the time of this picture, Comet ISON was 97 million miles from Earth, heading toward a close encounter with the sun on Nov. 28. Located in the constellation of Virgo, it is now visible in a good pair of binoculars. (credit:NASA/MSFC/Aaron Kingery)
