The TTS-160 Panther Mount is an Alt/azimuth mount. The alt/az mount has many advantages compared to the German Equatorial Mount: More compact stable design, only one axle to balance, no polar alignment needed, can view the entire sky while keeping eyepieces, cameras etc. placed at the same user-friendly angle (no meridian flip). The traditional alt/az mount has one problem when taking long-exposure astrophotos: Field rotation. With the TTS-160 Panther mount, this problem is eliminated using the unique telescope rOTAtor. So true equatorial tracking is provided in a compact, stable and fast package – just like the pros have done for years.
