This successful, 3-lens ED-Apo with 120mm aperture offers maximum sharpness on the axis and in the field. The fully adjustable triplet lens with a FPL53 Super-ED element shows a high-contrast image, free of annoying color errors. You can optionally get a 2-element image field flattener, this corrects the field and enables impressive astro images. The working distance of the flattener is generous, for example to enable the use of filter drawers or off-axis guides. The 3" focuser has a 1:11 reduction and enables a 360 ° rotation of the camera. The 120mm Esprit is a very popular choice of many astrophotographers.
For photography in combination with the flattener, we can setup all the necessary adapters up to the Canon EOS adapter ring. We would also be happy to make you an offer for the integration of additional accessories such as off-axis guiders or the use of other cameras.
This bundle includes our APM Riccardi Reducer 0.75x. Now you can turn this scope into a wide field astrograph with f/5.25 (f.l. 630mm)!
