Its advanced 4-element FPL-53 optics deliver high-resolution wide-field images, while the innovative internal focuser design prevents sag and tilt, even with heavy imaging accessories.

## Description

Discover a new dimension in astrophotography with the Spacecat 61 Astrograph f/4.9, a strikingly sleek telescope engineered with precision. This masterpiece combines advanced optics with a fast f/4.9 focal ratio, allowing you to capture stunning celestial images with ease. Decked out in an elegant space grey finish, the Spacecat 61 not only performs brilliantly but also adds a touch of sophistication to your stargazing adventures. Experience the pinnacle of astronomical photography with Spacecat. The SpaceCat 61 is based on the latest version of the Redcat 61 and features the same tried-and-tested optics as previous versions, so it provides high-resolution images when used for astrophotography or wildlife photography. Its fast f/4.9 focal ratio and compact size make it ideal for convenient wide-field astrophotography, and the WIFD (William Optics Internal Focuser Design) is integrated inside the main tube assembly, so no focuser drawtube movement is visible from the outside. One of the most significant benefits of the WIFD is that you can add several heavy accessories to your imaging train, such as a large filter wheel or rotator, without worrying about sag from the telescope focuser drawtube and the resultant tilt of the sensor with reference to the optical axis.
