Camera
QHY178M
$1,023
The QHYCCD Small "COLDMOS" camera series includes all of our cooled cameras with BSI (back-illuminated) and FSI (front-illuminated) CMOS sensors in optical format sizes smaller than 1 inch. These same sensors are also used in the uncooled QHY5III Series cameras. However, as the name implies, the Small COLDMOS camera models include efficient TE cooling as well as other more advanced features not found on the uncooled models.
Features
• USB 3.0
• Regulated TE Cooling Delta -40C
• 128 MB DDR Frame Buffer
• ST-4 Compatible Guide Port
• Filter Wheel Port
• Anti-Noise Technology
• Anti-Amp Glow Technology
• Anti-Dew Technology
These additional features include a heated optical window to prevent external dew, a desiccant plug socket to help maintain a frost-free CMOS chamber, a 128MB frame buffer, a filter wheel port Dual-stage TE cooling reduces the sensor temperature to -40C or more below ambient and temperature regulation maintains a constant temperature set point. Due to the efficient TE cooling, single exposure times up to 30 minutes are possible on most models, making them suitable for deep space imaging of dim objects as well as brighter objects and planets.

All of the Small COLDMOS cameras use Sony Exmor CMOS sensors. Two models, the QHY178 and QHY290, use Sony STARVIS Exmore R back-illuminated sensors. STARVIS is Sony’s designation for sensors capable of recording under starlight. These sensors have improved sensitivity and noise reduction - the key factors to enhancing image quality, while radically realigning their fundamental pixel structure from front-illumination to back-illumination. It retains the advantages of CMOS image sensors such as low power consumption and high-speed operation while dramatically improving sensitivity. With a conventional front-illumination structure, the metal wiring and transistors on the surface of the silicon substrate that form the sensor's light-sensitive
area (photo-diode) impede photon gathering carried out by the on-chip lens, and this has also been an important issue in the miniaturization of pixels and widening optical angle response.
Returns Policy
You may return most new, unopened items within 30 days of delivery for a full refund. We'll also pay the return shipping costs if the return is a result of our error (you received an incorrect or defective item, etc.).
Items that have been opened, damaged or are otherwise unsaleable will be subject to a minimum 10% restocking fee, to be assessed by Telescopes Canada upon receipt of the returned goods
