    Hi Mike

    You do not need to justify your interest in CN.  No one has ever been required to do so.  There has never been a string of sworn statements, indicating why it is permissible for them to participate.

    Perhaps you misconstrued David's question.  It appeared to me that he was asking why you were investigating the direction of the pole with respect to the ecliptic, not why you were interested in CN.  At least, that's the way I read the question.  Your milage may differ!

    There are several wobbles that the pole takes.  The Chandler Wobble is worthy of a look.  The effect on CN?  Zilch!  Still fun to look at, to tease the brain cells.

    Another deep time consideration, since that appears to be the question, is where the stars will be in 26 thousand, 26 million or indeed 26 billion years.  They all are moving with respect to each other of course.  The stars are not fixed in the firmament, they all have 'proper motion' from our perspective.  The Almanac will neccesarily change over time to reflect the actual positions, should anyone need this arcane data in 100 years, but it is worth consideration

    The numbers may not lie but I would like to be aware what they are, I would like to have a better understanding.

    Why do I care?

    My family has probably the worst record of dementure on the planet, from both sides of the family. I have 7 close relatives that have or are suffering. Grandmother, mother, uncles and aunties and 1 cousin. I naively believe if I keep my little grey cells active I might just delay the inevitable. I have had boats for 40 years and have worked at sea but have never had the need to study Celestial Navigation. I happen to have chosen something to study which is related to my interest. Many people of my age choose to pass their time watching TV but this is not for me.

    Currently I have a little gaff cutter and enjoyed 140 days sailing in 2019, adding up all the hours in my log I spent just under a month at sea, sailing, fishing and filming whales, seals and dolphins. Usually sail all winter but mast down for repairs at the moment. Keeping active - another vain attempt to delay the inevitable.
