Canon unveils the EOS 60Da
Canon expands the EOS series with the launch of the EOS 60Da – a high resolution Digital SLR (DSLR) designed for astrophotography. Based on the specifications of the EOS 60D and succeeding the EOS 20Da, the EOS 60Da is designed to capture rich red colours produced by emission nebulae, with a modified low pass filter that makes it more sensitive to hydrogen-alpha (Hα) wavelengths of light.
The EOS 60Da is ideal for shooting astronomical phenomena such as diffuse nebulae – a favourite among astrophotographers due to the distinct red colour caused by the ionisation of hydrogen. In a standard DSLR, an infrared (IR) filter limits the amount of Hα light that passes through to the camera sensor, reducing the transmission of red signals to prevent unwanted colour artefacts in the final image. However the EOS 60Da features a new modified filter that offers three times more transparency for Hα light than the EOS 60D, combined with an 18 megapixel CMOS sensor, DIGIC 4 processing and a high ISO range to capture crisp, clear images of red-coloured emission nebulae.
High resolution, high sensitivity and low noise
The EOS 60Da provides astrophotographers with high performance and creative flexibility. Its 18 Megapixel APS-C CMOS sensor is ideal for capturing rich detail in star clusters, and advanced performance at high ISO speeds up to ISO 6,400 (expandable to ISO 12,800) ensures images are low in noise, reducing the need for longer exposures and star tracker mounts. Working alongside powerful 14-bit DIGIC 4 processing, the sensor also provides excellent signal-to-noise ratio in final output data, producing pictures that are rich in natural colour with smooth tonal gradations – ideal for capturing the subtle colour transitions of interstellar gas clouds, for example.
Utilising the advanced ergonomics of the EOS 60D, the EOS 60Da has been designed to be comfortable to hold and highly customisable. A curved shape features an easy-to-reach button layout, with frequent controls grouped together for easy access. Controls can be easily adjusted and reassigned to suit each user’s individual requirements, and a top LCD screen with backlight illumination provides additional flexibility to monitor and adjust image parameters mid-shoot. A dedicated Quick Control button also provides instant and convenient access to the full range of camera settings during shooting.
The EOS 60Da also features a 7.7cm (3.0”) Vari-angle wide LCD screen and Live View support – ideal for composing shots using a tripod. The screen’s Vari-angle hinge provides flexibility, while Live View mode provides convenient, precision control, allowing photographers to finely adjust composition and camera settings. The LCD’s fine 1,040k-dot resolution also provides exceptional levels of on-screen detail during and after shooting, allowing astrophotographers to compose and review their shots with confidence.
For more flexible shooting, the EOS 60Da is compatible with the optional Timer Remote Controller TC-80N3 – a programmable remote shutter control that allows the adjustment of settings without disturbing the camera’s position. The TC-80N3 provides the flexibility to remotely capture images at custom-selected intervals or shoot exposures over long periods, making it ideal for shooting time lapse movies of the night skies. A supplied ACK-E6 AC Adaptor allows continued shooting using mains power – ideal for long exposures – and EOS Utility software allows users to control settings, or view the framed image from a PC or Mac connected via USB mid-shoot.
As part of the EOS System the EOS 60Da is also compatible with the world’s most comprehensive selection of interchangeable lenses, ranging from the 8mm to 800mm – providing both power and exceptional creative choice for astrophotographers.
