A few from Friday night - M1 & M82

[Ian]

both really. In fact, without that sort of processing you'd not get images from Spitzer or Chandra, being IR and X-Ray respectively. There are many advantages to using a mono camera and filters, but bear in mind, cost isn't one of them

[Daniel]

Just as an experiment, could I change my camera to monochrome mode then shoot 3 images with seperate R G and B filters then add these into a photoshop file in the correct channels?

[Rick]

A colour digital camera usually has a mask on the detector. When you mix that with filters you sometimes get real weird effects...

[Daniel]

I might actually try that then, just to see what it comes up with!
