In this article, I intend to describe how to image planets using a web camera as the main imaging device and then provide a brief overview of the post-processing technique.Any web camera may be used for astrophotography, some cameras however, perform better than others.
Mathematically, it can be shown that averaging a lot of marginal images in this manner improves the result dramatically.
As you might imagine, that’s not a simple question.
Live streaming cameras vary widely in quality, price, and the details of how they connect to your system.
This is rather new and there isn’t much software that can take advantage of it; however, with a little tweaking and hacking we can get the H.264 stream into Gstreamer, where after we can do pretty much whatever we want. One significant exception is that it has a hole for mounting it on a standard photo tripod.
The camera can work in three different modes: YUV 4:2:2, H.264 and MJPG: # v4l2-ctl --list-formats ioctl: VIDIOC_ENUM_FMT Index : 0 Type : Video Capture Pixel Format: 'YUYV' Name : YUV 4:2:2 (YUYV) Index : 1 Type : Video Capture Pixel Format: 'H264' (compressed) Name : H.264 Index : 2 Type : Video Capture Pixel Format: 'MJPG' (compressed) Name : MJPEG For each of these modes, the C920 has a huge amount of frame size and rate combinations going from 160×90 to 1920×1080 at 5 to 30 fps. the framerate is reduced at high resolutions in YUV mode, and there are also a few higher resolutions for shooting stills.
