DSLR Imaging Question
Just a quick question, when imaging with a DSLR, do most people add something like a 2" UV/IR filter in front of the camera to protect the CCD sensor from dust?
I have always simply attached the camera to the telescope focuser but now wondering about the dust element into the camera CCD when whether I should get a clear filter to thread onto my nose piece/camera t-adaptor.
