Thanks guys
Hi Zubenel and Rob_K. The only filter I have is an old "Deep Sky" filter I bought years ago from Astro Optical. It works reasonably well on emission nebulae and planetaries, but kills starlight. So, even though it gets rid of skyglow and adds contrast it tends not to work on galaxies, and colours what you can see of them a nice shade of blue. If anyone knows of a filter that helps bring out galaxies I would be interested to hear of it.
I will have to be more systematic and start keeping a notebook. I am sure I saw more galaxies than the ones I mentioned. They are only the ones I remembered. The wife tends to collect my scribbles on bits of paper and not all of them survive cleanup mode!!!
