Hi All, well with my tree line this may be the last chance I'll have to image it for quite a while. Went a bit deeper with 6 x 300s exposures with the Canon 40D at ISO800 and via IDAS-LPS filter and 0.8reducer in the YO ED80 at F7.
It's a slight improvement noise-wise on my last attempt with the ED80 at least
Comments and advice welcome.
