Using the same 155EDF refractor, I was able to get three exposures of 10 minutes each. The sky down there in the Andes was ultra-clear, compared to what I am normally used to. Lots of deep sky objects were naked eye that require at least binoculars up here where I usually image.
Of course, this image has some noise, it was only 3 exposures of 10 minutes, but it does show what kind of detail can be achieved with modest apertures under pristine skies.
