About the Lunt Solar Systems - Lunt Solar Imager...

We get asked all the time which camera is best with the Lunt Solar Telescopes and Lunt Solar Filters, and now we can say ours! Below are the details of the Lunt Solar Imager (LSi). Lunt will provide full support and instructions for Solar Imaging.

The Lunt Solar Imager camera uses a 2/3" format CCD which is ideally suited to fit the whole of the sun on to the CCD in one image. It also has larger pixels which have larger full-well depth and incredibly low read noise which allows the CCD Camera to produce a very high dynamic range. It uses a 16bit A/D converter giving 65,536 grey levels compared to 8bit (256 grey levels). To get the best image from an 8 bit camera you need to take lots of over exposed images and average them together to build up the good data on the prominences and then take a lot of images, under exposed, to get the surface detail, and then add all the frames together. Because this LSi camera has such a large dynamic range, you are able to capture both the prominences and the surface detail in one image and with the exposure times so low, you can almost freeze the seeing conditions.
