Thanks Raymo and John. Camera sensor colour response no doubt makes a difference. I can see the flame nebula clearly in both of John’s shots as well as the red background nebulosity of the Horsehead in the first shot although the JPEG compression has distorted that a little.
I’ll give it a go myself over summer and see what I get with different exposures, f stops and focal lengths on both fixed and tracked platforms with a couple of different cameras. I never quite caught the astrophotography bug although I did dabble with film in the late ‘80s for a little while.
