5 seconds of arc and never ever exceeding three seconds. The ensuing photographs confirmed perfectly spherical stars with exposures ranging from 5 to 10 minutes in a focal size of 600mm. I had been very pleased by this final result and rapidly formulated a way of self-assurance from the check here mount and its skills. With further use it did from time to time display an uglier facet.
