Barrel distortion can be visible at close focus distances, but that's not an issue for astrophotography. Chromatic aberrations are negligible, while coma and astigmatism are very minimal. Sharpness is both very good and extremely consistent across the image frame. It's markedly better than Irix's rival 15mm f/2.4 Blackstone lens or a Sigma 14mm f/1.8 DG HSM Art. In our review, we were hugely impressed by how well this lens maintained its image quality when wide open, which is hugely important for astrophotography. To be fair, though, if you’re photographing the Milky Way, you’ll need clear, dry and dust-free conditions. There’s no weather-seal ring on the mounting plate to guard against the ingress of dust and moisture.

The rubberized manual focus ring gives a very assured grip and has a long rotational travel with a fluid feel. The high-quality glass is neatly wrapped in a really solid casing. The lens is sold as the Rokinon SP 14mm f/2.4 (opens in new tab) in North America. But whatever system you're using, chances are good you'll be able to find a good astrophotography lens on this list.įrom Korean manufacturer Samyang’s XP stable of premium manual-focus prime lenses for Canon and Nikon full-frame cameras, this 14mm f/2.4 is the most ideal for astrophotography. First up we run through our favourite astrophotography lenses for multiple mounts, then we have specific sections for Canon, Nikon, Sony and Fujifilm shooters. We could say more, but check out our astrophotography tips (opens in new tab) and how-to guides (opens in new tab) if you need more tips. Using slow shutter speeds is also necessary for this, which is why you need that tripod we mentioned.

You can use a zoom or a prime a focal range of about 14-20mm is best (in full-frame terms, so that's about 10-14mm on APS-C or 7-10mm on Micro Four Thirds).Ī wide aperture is also necessary to allow the sensor to drink in as much light as possible, so that you can keep the ISO low and the shots clean. Why a wide-angle? You want to be able to capture as much of the sky as possible, and a wide focal length will ensure the broadest possible perspective.

The TOTEM experiment involves about 100 scientists from 16 institutes in 8 countries (August 2014).

This new level of collaboration will lead to results of unprecedented accuracy, including measurements of the invariant mass created in the collision. In 2015, the TOTEM and CMS collaborations will coordinate the use of their detectors to perform combined measurements.

Named for their shape and first use by physicists from Rome in the 1970s, 'Roman Pots' are unique for their ability to move sensors both vertically and horizontally in the accelerator vacuum.

Meanwhile, 'Roman Pots' with silicon sensors perform measurements of scattered protons. The 'telescopes' – T1 and T2 – use cathode-strip chambers and Gas Electron Multipliers (GEM) to track the particles emerging from collisions at the CMS interaction point. TOTEM has almost 3,000 kg of equipment, including four particle 'telescopes' as well as 26 'Roman pot' detectors. This region is known as the 'forward' direction and is inaccessible by other LHC experiments.Īs CERN's 'longest' experiment, TOTEM detectors are spread across almost half a kilometre around the CMS interaction point. This is the physics that the TOTEM experiment is designed to explore, by taking precise measurements of protons as they emerge from collisions at small angles. When protons meet head-on at the Large Hadron Collider (LHC), the collisions provide a micro-laboratory to investigate many phenomena, including the protons themselves.
