Ships' Clock: Astro

[Danny Jo]

I'm sure some computer geek will give a better method, but you could click the reply button and the whole thread will be below the reply window without the annoying pic's and avatars; select the lot, copy and paste into word.

There are a couple of options in the Thread Tools menu: Printable Version will give you something you can cut and paste into Word. email will let you send it to your mailbox.

Thank you.

Both of the above are a whole lot better than trying to copy the whole thread as displayed and pasting into Word - my steam age PC spent the best part of seven minutes grappling with its overloaded "notepad" before presenting me with a Word document of planetary proportions.

Postscript: "printable version" produces at 44 page document, replacing double line breaks with paragraph marks reduces it to 35 pages; "email this page" simply emails the page's URL. Now all I need is a macro that goes through a document converting tables to text.

we find WINASTRO www.winastro.co.uk very good accurate and easy to use.

Don't know about "common practice" on a recreational yacht, but I suspect not.

Volume 1 of AP 3270, Selected Stars, makes planning and reduction of star sights a doddle, although the actual observations can sometimes be a little more demanding than sun sights. The main problem with AP 3270 is its sheer bulk and the fact that Vol 1 is only good for the current epoch.

It is possible to buy AP 3270 or the US equivalent, HO 249, in reduced format, but the print is so small that it is a bit difficult to read. You can also download just the (full size) pages you want, for free.

If these bulky volumes are difficult to stow on most boats, there is always the calculator option, freely available software for your laptop or my personal no-battery-required choice:

The Complete On-board Celestial Navigator by George Bennett.*


This slim, spiral bound volume is a compact and simple to use set of tables and long term almanac. Unfortunately the long term almanac in the current edition is only valid to 2011, so perhaps a bad buy at the moment.

* no connection, commercial or otherwise!
