Cooled CMOS Camera with Built-in 9-Position Filter Wheel 

If you think a cooled camera with a built-in motor-driven filter wheel has to be expensive, then think again!  QHYCCD is proud to release the miniCAM5F, a highly-sensitive, cooled, CMOS camera with a built-in nine position motor driven filter wheel for only USD699.  This feature-rich camera includes regulated two-stage TE cooling that can lower the sensor temperature to -38C below ambient.*  The sensor has a peak QE of 74%.  And the 1.2 Megapixel camera is capable of capturing full 1280x960 pixel images at 30 frames per second, or 320x240@200FPS, with extremely low read noise of 2 electrons!  You can install the L, R, G, B, Ha, OIII, SII, CH4 and a black filter (for dark frame capture) all on the same filter carousel.  

Another great benefit is that you can get these filters very inexpensively. Astronomy filters are usually a huge expense for monochrome cameras, especially when collecting the entire set. Often, you may spend more than USD1000 for a set of 1.25-inch L, R, G, B, Ha, OIII, SII filters. However, since the miniCAM5F utilizes our smaller, QHYCCD-defined, 12mm mini filter size, you’ll save a lot. The miniCAM5F can be bundled with L, R, G, B filters, as well as the optional Ha, OIII, SII, H-beta and CH4 filters for just USD50 each. We believe these filters will be a lot of fun to play with not only for your planetary imaging but also for capturing your favorite DSOs!

(*) Note: Delta T has changed from -45C to -38C (November, 2015).

Note: Although this camera has C-mount threads, its back focus is about 20mm so it does not support the back focus requirement of C-MOUNT lenses. The camera comes with a 1.25inch C-thread T-ring used to connect to the telescope.
The miniCAM5F has a peak QE of 74%.  The 1.2 Megapixel CMOS sensor is very suitable for capturing smaller objects like planetary nebulae, small galaxies and globular clusters. If you have a short focal length OTA, it is also ideal for big, diffused nebulae. The miniCAM5F is a really mini camera, so it is excellent for building a compact imaging system.

The camera has full anti-moisture features, including a built-in heater board to prevent moisture from forming on the CMOS chamber window as well as the option to insert bundled silica gel tubes into the CMOS chamber when necessary.

Producing affordable, multi-purpose and high-quality cameras has been our goal. QHYCCD hopes this camera will pleasantly surprise you during your astrophotography sessions!

Color Moon miniCAM5F LRGB vs QHY5L-II-C
I am really amazed with the quality of the mono sensor with filters. It is much much better than the bayer sensor. I am very happy with the minicam5f. The details are of course better but the colors are really better. I will have a lot of work to do on the Moon.  --Alain
