The Nano.Tracker is very compact and fits really still in the camera bag - at the latest when one renounces a larger telephoto. This also makes its charm: he is an ideal companion for travel in dark regions where you already use a tripod while has, but can take no great Astro-mount or wants - be it when traveling by air or trips into the mountains. A second ball head arrived.
The polar alignment using the monitoring well is to say the least a bit tedious because my tripod has a very large platen; with the recommended iPhone app push to it was not a problem: set the phone to the Nano, and targeted 90 ° Dek - so it was even better polar aligned as if I had targeted only the Polarstern.
The load should be limited primarily only by the ball head used, the unit makes a very solid impression. An SLR with a wide angle lens is likely to overburden him hardly. For Sternfeld Photography up to 50mm it works very well, much longer focal lengths combined with long exposure times I want him without a real Polsucher not necessarily expect (a lunar or solar eclipse in 200 Tele should not be a problem, because the exposure times are short, and an inaccurate polar alignment is not a problem). With 100 or 200mm and long exposure times probably already worth a proper mount, but is then also correspondingly massive. A little tip: With a Cokin P830 Blur filters are bright stars somewhat "inflated", and the constellations can be seen better.
Only two things I have to complain about, which are to get over in practice for the price, however: The power consumption is quite high (can be a set count batteries per night, and unfortunately there is no input for an AC adapter / car charger) and there is no charge indicator. After the battery change is not a problem: The battery compartment is in the hand box, so you will not trigger the tripod when changing the batteries. The price advantage over the competition is still no reason for a trigger, even if a repair would be desirable.
Those looking for an affordable entry into the starfield photograph, is right with this device. Beautiful constellations that require a little more exposure time (whether or comet encounters between planets with clusters) can be so much better to hold the image as without tracking, and only by the addition of several images are magnificent images at all possible.
