Alan, Mike, Greg and Bojan if you liked the image here is a larger high resolution version. It takes a lot longer to upload it than download it. The 128kbits/sec upload speed limitation is a constant annoyance.

Bojan I spent forty years using my technical expertise to make my bosses famous. I am quoting them. My group leader was once asked by a TV crew (that was interviewing him) what Bert's job was in the lab and he said ' it is Bert's job to use his skills to make us famous!' His tongue was firmly in his cheek.
Now in retirement I can maybe do a bit more for myself as well as passing on any new methods.
This very difficult hobby of astrophotography keeps me as sane as I was last week. I will get bored with it when I cannot further improve. Fortunately this will not happen as there is constant exchange of ideas and stimulation on forums like this that stops us from going stale.
