Although the stages of starting the instrument are straightforward, a sheet of step-by-step instructions would greatly simplify the matter. No further instructions are provided other than in the app, which involves first creating an account while connected to the Internet and then switching on the instrument. The app now required is called Singularity. We encountered a slight problem here because the instructional video referred to an outdated app, Stellinapp, that no longer functions. Next, you download the control app to your phone or tablet. The battery provides up to five hours of observation. (Image credit: Robin Scagell)Ī brief online video shows you how to attach the separate short, stubby tripod and plug in the battery, which you need to charge separately using a standard AC charger for USB devices (not supplied). Power is provided by a battery pack, giving up to five hours of observing. The app then stacks these automatically, building up the total exposure time using many individual exposures. This results in a rotation of the image which is compensated for internally, and by limiting exposures to only 10 seconds each. Unlike most amateur telescopes designed for imaging, the Stellina has a simple altazimuth mount, with up–down, left–right movements only, rather than the more complex equatorial mount that requires alignment with Earth's axis. However, it appears to be robust and we had no problems with the unit not working after a car journey. There are no grip points or handles, and the smooth casing is quite slippery so you need to take care. It is quite weighty and not trivial to carry around, although the ads show it being backpacked by fit young men. The suitcase-shaped instrument is sleek and shiny, and to some extent belies its power to find and take images of a wide range of objects. The only setup required is to level the instrument using the bubble level.
