QHY8 is a color camera.
The Bayermatrix ...Hi Dick!<br /><br />QHY8 is a color camera.<br />The Bayermatrix in the ccd is not a good match with narrowband filters.<br />Exampl. H-alpha is using only Red pixels, so only 1/4 of resolution of the ccd is used.<br />In B&W camera, all the pixels are used, hence the reolution is four times higher.<br />The sensitivity of B&W ccd is higher too.<br />I still have the QHY8, and I'll use it this winter to shoot broad band color images in a dark place, outside of city lights.<br /><br />As you can see, both cameras are very suitable and versatile for astroimaging.J-P Metsavainiohttps://www.blogger.com/profile/17779793358827771439noreply@blogger.comtag:blogger.com,1999:blog-6953966401086641771.post-38924395987945022372009-08-19T12:18:51.982+03:002009-08-19T12:18:51.982+03:00Hi, why do you make a switch to the monochrome Qhy...Hi, why do you make a switch to the monochrome Qhy9 if you make this wonderfull!! narrow pictures with a colour camera Qhy8?
