The Sky Rover 130SAP is a 130mm f/5 specialist astrograph built around an air-spaced quintuplet Petzval APO design. With its native flat field and 55mm image circle, it is designed for medium-format astrophotography without the need for a separate field flattener.
One of the biggest strengths of the 130SAP is its naturally flat field. Sky Rover positions the SAP series as a high-performance imaging platform with tighter star points, strong illumination across the field, and improved focal plane stability, making the 130SAP especially appealing for larger sensors.
With a focal length of 650mm and a fast f/5 focal ratio, the 130SAP is designed for bright, detailed deep-sky imaging. The Petzval quintuplet optical system uses dual SD glass, one ED element, and HR glass to deliver strong correction and a more convenient imaging experience without separate back focus calculations.
The telescope features a 3.7-inch dual-speed rack-and-pinion focuser with 42mm of effective travel, giving it the precision and rigidity needed for larger imaging trains. It also includes a Losmandy-style dovetail plate, tube rings, and a handle for a stable and practical mounting platform.
The 130SAP is designed as a dedicated astrophotography telescope rather than a general-purpose optical tube. Its native flat-field layout, large rear interfaces, and medium-format coverage make it a serious option for users building a premium wide-field imaging setup.
