The NEW ZWO ASI120MCis an excellent choice for an affordable planetary camera or deep sky one shot colour camera for those who has just started in astro photography, but cannot spend a fortune on a specialist astro photography camera or want to replace a modified webcam or a cheaper planetary imager. This NEW version also comes with an ST4 AUTOGUIDER PORT so you may now use it both for imaging or guiding!
The QHY5-III 290 Mono uses a SONY STARVIS Exmor R back illuminated CMOS sensor. The Starvis sensor allows you to “see” very dim stars in real time video. The QHY5-III 290 can capture mag 9 stars when connected to a 50mm F1.4 C-mount lens. Compared with the IMX236 sensor it has twice the sensitivity to visible light and more than three times in the near infrared.
QHY16200A APS-H Format Monochrome CCD 16.2 Megapixels
The QHY16200A uses the ONSEMI 16.2MP KAF-16200 CCD. The APS-H format is suitable for most telescopes, including SCT’s that cannot fully illuminate a 35mm frame without some vignetting or distortion at the edges. It is also suitable for commonly available 2-inch filters.
The QHY21, QHY22 and QHY23 cameras feature Sony’s latest high sensitivity ExviewII CCD sensors: ICX674, ICX694 and ICX814.
These sensors has very high QE (close to 80%) and very low thermal noise.
With dual stage TEC cooling technology these cameras can achieve temperatures 45C below ambient. By comparison with the competition, the 10 to 15C of extra cooling helps ensure great results, even on hot summer nights!
