There seems to be a few different versions of this book, aside from the second edition, Can someone lucky enough to own this book please post the isbn for me or let me know the best place to get a copy.
I recall back in 1969 when I was a cadet engineer in Sydney haunting the various second hand bookshops in George St, Sydney. Hartung's "Astronomical Objects" must have been in the window of one of the bookshops for a couple of months at least but at a cost of $6.75 it made a fair dent in my $30 a week pay packet. I gave in to temptation and can honestly say it is the most memorable and satisfying book purchases I have ever made. It has been used on countless occasions, lent out to various fellow amateur astronomers over the years yet is still in quite excellent condition. I bought the 2nd Edition in 1995 from Melbourne University Press at a far greater cost of course and while it is a great book it did not evoke the same feeling I had for the 1st Edition. These days both books sit in the bookshelf except when I read this thread, now it is time to re-acquaint myself with a couple of old friends.
A word of advice, cover your books with a good quality plastic sleeve/dust jacket in the first instance, it will keep them in perfect condition for many years. I have attached some scanned pages of the 1st Ed for people who may be interested.
I was in South Africa in the 1970's when I heard about Hartung's book. I was lucky enough to be able to contact him and request his help to find a copy; he did better than that, he sent me one of his copies which he had annotated with corrections.... certainly a wonderful piece of work.... will always be in the library.....
Unfortunately by the time I came to Oz, he had died and the bushfires wiped out the observatory; I did go up to Lavender Farm just to see..............
