Player One Apollo-C IMX174 Color Solar Camera

IMX174 Global Shutter: 164 FPS Capture Without Distortion

Solar imaging is a battle against atmospheric seeing. The Apollo-C's Sony IMX174 sensor uses a global shutter, which exposes every one of its 2.3 million pixels simultaneously. This completely eliminates the wobbly, distorted "jello effect" that rolling shutters produce when imaging through turbulence, ensuring solar granulation and spicules remain sharp and geometrically correct.

At full 1936x1216 resolution, the camera streams 12-bit data at 164 FPS over its USB 3.0 port. This extreme speed is critical for "lucky imaging," allowing you to capture thousands of frames in a short period and select only the sharpest ones, frozen in moments of perfect seeing.

Solar-Specific Engineering: Passive Cooling and Newton's Ring Mitigation

Operating in direct daylight subjects a camera to significant heat. The Apollo-C incorporates a Passive Cooling System (PCS) that uses a high-density sponge and thermally conductive materials to draw heat away from the sensor. This helps manage thermal noise during long capture sessions, a critical factor for maintaining image quality.

For narrowband H-alpha imaging, Newton's rings can be a persistent source of interference. Player One has integrated a unique mechanical tilt plate into the Apollo-C's design. This allows you to make micro-adjustments to the sensor's angle relative to the incoming light path, effectively canceling out the interference patterns and producing cleaner, smoother final images.

Onboard DDR3 Cache: 12-bit Data Integrity at High Speeds

To ensure stable data transfer at high frame rates, the Apollo-C is equipped with an onboard DDR3 cache. This buffer prevents dropped frames by ensuring the data flow from the camera to your computer remains consistent, even if the PC's resources are momentarily taxed. This feature is crucial for maintaining the integrity of your video files, as a single dropped frame can disrupt post-processing.

The camera also features Dead Pixel Suppression (DPS) technology. By mapping out non-responsive pixels from dark frame analysis, the camera can correct these blemishes in real-time during capture, saving you valuable time in post-processing.

Apollo-C vs. Apollo-M: One-Shot-Color vs. Monochrome Solar Imaging

The Apollo-C shares its high-speed IMX174 global shutter sensor with its sibling, the monochrome Apollo-M. The choice between them depends entirely on your imaging goals and workflow.

• Apollo-M (Monochrome): The monochrome version offers higher sensitivity and resolution for dedicated narrowband imaging (like H-alpha or Calcium-K). By capturing all incoming photons without a Bayer filter, it provides the maximum detail for scientific or advanced amateur applications.
• Apollo-C (Color): This model provides the convenience of one-shot-color imaging. It's an excellent choice for capturing white-light solar views with sunspots, full-disk images showing chromospheric color, or for those who prefer a simpler, faster workflow without the need for a filter wheel and post-processing color combination.
