Impressive focal length
The A105MII's 1,000mm focal length makes it ideal for viewing a variety of astronomical objects, including the Moon and planets, plus a wide range of deep-sky objects such as planetary nebulae, galaxies and star clusters. It also allows the use of lower powered eyepieces for improved 'eye relief - the distance your eye must be from the eyepiece to see the entire field of view - to ensure a better observing experience, as well as helping astronomers who wear glasses. The 105mm aperture provides a proficient level of light-gathering capability to enhance the viewing of faint and fuzzy objects, without the scope becoming difficult to manoeuvre. Generally, refractors are simple enough for beginners to use confidently, as they don't require collimation or a complicated setup routine. They also tend to offer the most natural and satisfying viewing experience, with good background contrast and sharp stars, allowing users to explore open clusters and other stellar phenomena.
As soon as we unpacked the Vixen A105MII achromatic refractor, we noticed its impressive build quality - there's not a piece of plastic in sight. It was also pleasing to discover that the optical tube comes with some robust accessories, including a handy, metal flip mirror diagonal - a unique addition and one that allowed us to switch from visual to imaging targets with ease. Feeling eager to put this 105mm refractor through its paces, we headed outside.

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.
