I just wanted to point out an error in your letter. I know that it isn't very important by if the reader of the letter see it then he/she may not take as much notice.
The brightest star in the sky is not Vega.
It is Sirius.
The stars are as follows:-
Star Apparent Magnitude
Aplha Centauri A -0.01
This shows that Sirius (and three others are bighter than Vega). I don't like to nit-pick but the reader of the letter may (like me) spot the mistake immediatley and it looks better if the letter appears to be written by a profesional. I'm not saying that it does not but some people take the smallest mistake and assume that it was written by an amuteaur.
I'm not sure about the spelling.
Hmm, that really was a stupid mistake, don't know what I was thinking. I'll put that right.
