Software
AltairCapture software is included with the camera. It allows full control of all the camera settings - including heating and cooling, 'HCG' (High Conversion Gain), 'LCG' (Low Conversion Gain) and 'Ultra Low Read Noise' modes, region of interest imaging and real-time live focusing - all in a simple-to-learn, intuitive interface that keeps any distracting complications to a minimum.
The Hypercam AA61CFX is a full-frame, one-shot colour astronomy camera with 16-bit capability. Designed for serious astrophotography and dedicated enthusiasts, the AA61CFX represents a significant investment. Matching its high-end capabilities to the rest of an imaging setup is a crucial exercise, as this camera will quickly reveal any shortcomings in the equipment it's used with. For our tests we selected a high-grade mount on a permanent pier and a 150mm apochromatic telescope, which provided a large enough colour-corrected, flat imaging field.
Accommodating the large sensor at the heart of the AA61CFX requires a stocky camera body, which is the familiar barrel-shape design. The front of the camera comes with an M54 x 0.75mm female thread, which gives plenty of unobstructed room around the edge of the sensor. Being a one-shot colour camera there is no need for additional filters, as the sensor's optical window has built-in ultraviolet and infrared blocking, but additional specific band filters can be used if they are large enough for the sensor.

Could We Find Aliens by Looking for Their Solar Panels?- Designed to reflect ultraviolet and infrared, the panels have a unique fingerprint
Researchers searching for life beyond Earth spend a lot of time thinking about what telltale signs might be detectable astronomically. Forms of unambiguous evidence for the presence of life on another world are known as biosignatures. By extension, techno signatures are indicators of activity by intelligent, civilisation-building life.
Antimatter- In our continuing series, Govert Schilling looks at antimatter, the strange counterpart to most of the matter filling our Universe
Particles and corresponding antiparticles are very much alike, except they have opposite electrical charges. For instance, the antiparticle of the electron - known as the positron - has the same tiny mass, but while electrons carry a negative electrical charge, positrons are positively charged.
Where Have All The Milky Way's Early Stars Gone?- Our Galaxy has a curious lack of pristine stars
The Big Bang produced a Universe filled almost exclusively with hydrogen and helium; all other elements - what astronomers call metals - were produced by stars, supernovae and everything that happens later. So if you can pick out a pristine star with no metals polluting it from among the billions in the Milky Way, then you are likely to have a star dating from our Galaxy's earliest days.
