10mm more aperture doesn't sound much, but it already means an increased limit size and improved resolution, i.e. on a double star. The light collecting area is already approx. 30% larger than with a 100mm lens!
The focal length of approx. 805mm is chosen very universally, with our 0.75x Riccardi reducer a CCD-friendly focal length of approx. 600mm can be achieved. Those who love planetary details can choose from high quality Barlow systems. Sun observation is also a pleasure with the appropriate accessories. Here, too, this apo shows its class when it comes to definition and contrast.
