The Skymax 150 is a 150 mm Maksutov with an 1800 mm f/12 focal length. The larger aperture reaches fainter detail than the 127, while keeping the high-contrast planetary character of the Maksutov design.
Because magnification is the telescope's 1800 mm focal length divided by the eyepiece focal length, a 25 mm eyepiece gives 72x here and a 10 mm eyepiece gives 180x. The highest useful magnification is about 300x (roughly twice the aperture in millimetres), beyond which the image dims and softens without showing more detail.
The focuser takes 2 in eyepieces, so long 2 in wide-field eyepieces such as the Omni 56 mm fit as well as 1.25 in ones.
