The Zeiss mini quick is pricey I bought mine during a trip to cologne, Germany, a good number of years back for 100 Euros but then they're made in Germany so are probably cheaper there.I think in the USA you'd be looking at $160?the optics are very sharp but the twilight factor is not so good due to the tiny front optic,in fact there's not much difference twixt the front and the eye piece!it seems to use a roof prism but is long like a mini telescope. I've never taken it south of Bermuda so can't comment on what views it would give on things like 47 tucana, eta Carina,etc.I took a much larger 8x25 Opticron monocular on my trips to Australia and Brazil which gave very good views during the odd clear evening, yes cloudy in the Australian summer! Melbourne mid day in February 18c and drizzle!

 

Brazil,south Africa and Australia are the only countries in the southern hemisphere I've stargazed from. Brazil very little due to foolishly just spending a week in Rio de Janeiro instead of getting to the hinterland but it was mainly cloudy. Plus crime,real or imagined, is a deterrent to nocturnal or even daylight travel there. South Africa is quite good for the stars. Australia too on the odd clear night I had.Singapore almost counts being only 3 degrees north of the equator and the sun is overhead. It's very light polluted by I could clearly make out canopus and other less exotic,to the northern hemispherian,first magnitude stars from Singapore's canning park but gave up when a laser light show came on!in general I'd say that the 5x10 is too small for much but I got a good sun view using solar filter medium. I know you can see various m objects through it as I remember looking at m41 with it in the winter but compared with the 8x25 the view was poor still better than nothing.
