![]() Planetary capture is extremely data and speed intensive. You will need a computer with a USB 3.0 port. A laptop might be used for imaging in the field, with a more powerful desktop used for data processing later. Not much detail is visible without processing to bring out the details we’ve captured. Atmospheric turbulence varies, so using data only when it is lowest gives us the best possible results. Not having access to adaptive optics as professional observatories do, the main weapon in our arsenal is “lucky imaging”, a technique that allows us to take advantage of the moments when the atmosphere happens to be relatively still. To achieve the maximum possible resolution, we have to try to reduce the effects of the atmosphere, or at least identify times when it is least degrading to the image. The next release should include some modifications to help with capture on smaller displays and if I ever get my head around it at least some support for filter wheels.The actual theoretical resolution of a telescope is a lot higher than we can usually record through the atmosphere, especially with larger reflectors. Downloads of source and binaries for OSX, 32-bit Intel, 64-bit Intel and ARM (Raspberry Pi) Linux are available from oaCapture downloads where there's also documentation. I don't have any to test myself.įeedback is welcomed. The list on OSX doesn't include the SPC900 and probably only supports the Imaging Source and Skyris of the UVC cameras, but otherwise should be much the same. I believe the Celestron Skyris cameras should also work. USB cameras using the IEEE1394/IIDC/DCAM protocol such as the Point Grey Firefly MV and Chameleon should also work though I have only tested the first. Some or even many FireWire-connected cameras may also work though I have tested none. On Linux the cameras currently supported are the QHY5, QHY5L-II, the ZWO ASI range of cameras, SPC900 and UVC-compliant (or close) cameras such as the USB Imaging Source range and (at least some of) the Microsoft Lifecams. I've just released the latest beta version of my oaCapture planetary imaging application for Linux and 64-bit OSX (though it may well work on 32-bit as well if you were to compile the source yourself). ![]()
