Bresser HD Moon Planetary Guider 1.25″ Color camera
If you are looking for a reliable and capable camera for imaging the Moon and planets - and autoguiding at the same time - the Bresser HD Moon Planetary Guider 1.25″ Color is exactly what you need. It combines the high sensitivity of the Sony IMX225 chip with a practical ST-4 guiding port, serving two purposes in one compact aluminium body that fits any standard 1.25″ focuser.
Sony IMX225 chip - high sensitivity for planetary imaging
This color planetary camera features the popular Sony IMX225 CMOS sensor with a resolution of 1.2 megapixels (1280 x 960 pixels) and a pixel size of 3.75 µm x 3.75 µm. A quantum efficiency of 77% ensures excellent sensitivity even under less favorable observing conditions. The 12-bit recording depth provides sufficient tonal range for post-processing in software such as AutoStakkert or RegiStax. The sensor size of 4.8 x 3.6 mm corresponds to the 1/3″ format - a well-proven choice for planetary photography.
Video speed and exposure range
The camera supports video recording at up to 54.4 FPS at full resolution (1280 x 960 pixels), with a standard rate of 30 FPS. The exposure range from 0.105 ms to 16 minutes opens up possibilities not only for fast planetary video capture but also for longer exposures during guiding. Binning modes 1x1 and 2x2 allow you to adapt the signal-to-noise ratio to current conditions - 2x2 binning increases sensitivity at the cost of resolution, which is particularly useful for guiding in poor weather.
ST-4 guiding port - autoguider and planetary camera in one
The built-in ST-4 guiding port connects seamlessly to your mount via a standard ST-4 cable. This allows the camera to be used as a dedicated guiding camera with software such as PHD2 or Lin_guider, or as an off-axis guider together with shorter telescopes. This combination - planetary imager and autoguider in a single device - will be especially appreciated by observers who do not want to invest in two separate pieces of equipment.
Connection and compatibility
Power and data transfer are handled by a single 2-meter USB 2.0 cable, eliminating the need for an external power supply. The camera connects to the telescope via a standard 1.25″ barrel or a C-Mount thread, ensuring maximum versatility.
Operating system compatibility includes:
- Windows 8, 10 and 11
- macOS
- Linux
Users are not tied to any specific platform and can work with popular astronomy software such as SharpCap, FireCapture or INDI.
Who is this camera for?
The Bresser HD Moon Planetary Guider 1.25″ Color is an ideal choice for both beginner and advanced astronomers focusing on solar system objects - imaging the Moon, Jupiter, Saturn, Mars or Venus. Its compact size and low weight of just 90 g make it a practical travel companion that will not strain even smaller mounts. Thanks to the combination of a planetary camera and an autoguider port, it offers an excellent performance-to-price ratio for anyone who wants to get started with astrophotography or expand their existing setup.
