Cactus Patch Observatory / 14" LX200
"The four points of the compass be logic, knowledge, wisdom, and the unknown. Some do bow in that final direction. Others advance upon it. To bow before the one is to lose sight of the three."
Quote:This might also be of some interest to you and others. The new hardcover edition of "Explanatory Supplement To The Astronomical Almanac". Always wanted to buy one of these but wasn't sure if it would be helpful to an amateur astronomer without much mathematical background.
First and foremost observing love: naked eye.
Last but not least, telescopes.
And I sometimes dabble with cameras.
Quote:Tony,Would you explain? I'm not familiar with the "Supplement". I've always used the Almanac just for accurate positions of objects, mostly planets. What's in the Supplement that makes it valuable to the math-literate?
Quote:For those of you so inclined, this book is now available from the U.S. Govt. Printing Office. $40 delivered. If you wait until the end of the year, they'll be out of them. I buy one every year. I don't use it very often; but I love having the information handy when I do need it.
Quote:I got my Astronomical Almanac for the year 2013 today via postal mail. I was going through the tables and I find that dates given for all the planets, also includes December 32nd. Are we going to have 32 days in the month of December in 2013? Are there any changes to the calender in offing?
Quote:It doesn't much matter, what with the world ending on 12/21 and all.

Quote:What can this book give me that the "Observer's Handbook" from RASC - or Sky Safari Plus - can't?
