the camera is a starlight xpress SXV-H16, its a black and white camera designed for astro imaging. The colour comes from imaging through separate
colour filters, the data is put together in photo shop to produce the colour image that you see. A lot of people think they are false colour images,
mostly they are not, only the ones taken using sulphur, hyrodgen alpha and oxygen filters, these show a map indicating what elements are where. Here
are examples of the same object taken in both true color and narrow band light they can look quite different when compared

the light from these objects are so faint our eyes arent sensitive enough to see them so they often appear as a slight colourless haze or nothing at
all when viewed through an eyepiece....that was one reason wyh i took up imaging, i was quite disappointed when i looked through a telescope.
many hours of exposures and many hours of processing each image takes around 12 hours work some much longer....i love it when someone calls them
snaps!
a lot of the news papers said my kit cost £20,000 thats not true, ive actually spent £20,000 on the hobby over the years.....i suppose inaccuracies
are to be expected when you are dealing with the press
