Such advice applies to all CCD imaging and is especially important for narrowband imaging because of the small amount of signal passing through the filter.

Hi Jase
Thanks for tip #37
Will add to my study list.
Please feel free to suggest more as I still have a long way to go with my studies on Astronomical Imaging.
I appreciate all feedback that is constructive and helps me to get to grips with the complex issues.
Regards
Steve
