Nasty, snipey lot here, it seems. There have been quite a number
of posts over the years relating to the visibility of the moon and
planets. It does depend on the weather, after all.

Tudor, anyone with any scientific knowledge who takes seriously the
idea that Mars will appear the same size as the full moon hasn't got
a
clue. Gavin is, quote, a Fellow Member of the Royal Meteorological
Society, unquote.

Apart from his irritating habit of posting off-topic, he should know
better than to post that sort of rubbish here.

With all due respect, I don't for one moment think that Mars could
appear the same size as a full moon. I asked for some advice on this,
as this after all is a technical ng, and in moments someone very
kindly on this ng passed on the URL to me, which explained what was
going on. I have since forwarded that URL on to the person who sent me
that email in the first instance, and she has since replied saying
thank you. That's all there is to it. I am sorry that anyone was
annoyed by that:-(
I'll take this opportunity to say that this is be my last posting
on this ng, as it appears that my contributions regardless of whatever
I wish to say, are obviously no longer welcome:-(

Gavin.


I read the first posting and found nothing wrong. I remember that Mars'
diameter is given as 25 arcseconds. If one looks through a 75 X
telescope the angle becomes 1875 arcseconds or 31 minutes, the diameter
of the moon as we see it with the naked eye.

Am I mad or am I?
