Ever since I got this there has not been ONE day for viewing--The unit is very well made to perfection works nice with mirrorless camera --auto focuser next project
While I haven't even seen one of these in the wild, I seriously doubt that it would beat a 200mm Canon L lens which are selling used for a lot less than this scope. A brand new Canon 200 L has f2.8 actually costs less. If you haven't used an f2.8 lens for astro work, you don't know what you're missing. With AF, you could also use the 200 f2.8 lens for terrestrial with lots of filter options. NiteCat 51 is good if you only do astro, but will be interesting to see how this compares to Canon L glass.
