Abstract
The few amateur Schmidt-type astrographs which have been commercially available over the last few decades have suffered from the inconvenience of a curved focal surface and, because this surface is at prime focus, it does not afford a visual preview. This 146 mm (5.75-inch) f/3.9 Wright has several advantages over a Schmidt. It has flat focal plane and is significantly shorter (roughly half the size of an equivalent Schmidt). In its Newtonian form it has an easily accessible focal plane and hence can be used with ordinary SLR cameras. This makes it an ideal project for an ATM seeking to make an astrophotographic instrument.
