Thought I'd start a thread all about my time with a Heliopan 77mm TEN STOP NEUTRAL DENSITY FILTER bought from Amazon. Got it today.
Went down tonight to the seaside - weather very overcast and dull, also in failing light (wrong conditions to try it really) and this is my first poor effort.
I'm going to add images to this thread to document my 10 stop journey.
