Hi Peter, I have purchased Sky-Watcher 120x600mm OTA from Andrews last week. I’m using it for wide field imagining mainly and for this application I’m quite happy with it. With GSO 25mm eyepiece looking on the moon there is bit of yellow fringing around if you keep your eye right in the centre of the eyepiece. If you move your eye of centre, the fringing around the moon becomes quite pronounced yellow violet. Looking on Sirius I could see bluish fringing around. With other stars of lesser magnitude I couldn’t see any CA. The scope is well made and the focuser is reasonably smooth for R&P focuser. For its price I recon it is good telescope.
