wheel. Enhanced cooling increases camera depth by 11 mm and internal filter
wheel adds another 12.5 mm. The head is CNC-machined from high-quality
aluminum and black anodized. The head itself contains USB-B (device)
connector and 12 V DC power plug, no other parts (CPU box, USB interface,
etc.), except a “brick” power supply, are necessary. Integrated mechanical
