Optics
The 80mm (3.2-inch) objective lens is a fully magenta coated achromatic to help improve contrast. It has a focal length of 800mm, which gives the system a focal ratio of f/10. The tube is lightweight and fitted with pale green tube rings for attaching to the mount.
Tripod
The steel tripod is lightweight, yet sturdy enough to support the mount and telescope. It has adjustable legs to make the viewing height more comfortable, and it has a simple but useful plastic accessories tray that also helps to spread the tripod legs and keep them in position.
The Starbase 80 refractor and mount package from First Light Optics is manufactured on behalf of Takahashi in Japan. Although it is not actually made by Takahashi, the livery of the Starbase 80 is reminiscent of the pale green and white often associated with that company. The aim is to provide an entry level, grab and go achromatic telescope on a portable easy-to-use altaz mount, which will complement the usual high-quality Takahashi optical systems we are used to seeing.
The assembly of the Starbase 80 system proved to be straightforward, with the mount and tripod in one section, so all we needed to do was to attach the tube and rings to it, before adding the slow-motion controls and altitude clamp. Next, we added the star diagonal and an eyepiece and we were ready to go.

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.
