Pub. No. 249 makes life easier as I only need about 10 degrees of Latitude Same Name sheets.  Guess what time of year we sail?

We do mostly Sun sights and Stars using Vol. 1.

The celestaire Vol.1 epoch 2015 stars print out badly.  It always look motled and not sharp like vol. 2 and 3.  You get what you pay for.


Thoughts?

The moon's easy to shoot but does anyone bother with it?

Probably, if it's the only object available- ya got ta' take what you can.

For plotting I use mini-parallel rules and a small t-plotter from some scrap plexiglas.  Works good.

Hey, looks like the Naval academy is going to teach CelNav.

Surprise surprise!

New member here.

Which do you prefer to use during CelNav work- a pencil or a pen?

Me?  A #2 mechanical pencil from Walmart.

Cheap replacement lead can be bought at DollarTree.

Good stuff.

I assume we're all sailors here.

What kind of boat do you have?

What's your location?

I've got Catalina 30 Mk III Tall-rig.

Location- Palm Beach, FLA but I'm selling the boat (with any luck next week) and moving this Spring- North!

Index cards are very handy for writing down shots- it's what I use. 

Maybe there's a quicker and easier way- what do you write the sights down on?

The filters on my sextant are getting dirty/salty.  What should I do to clean them?

How about cleaning the index mirror?

Is there any concern about scratching the filters or the mirror?

Do any of you have pictures or plans of an Artificial Horizon you've made?

I want to make one and it would be nice to see other examples.

What fluid do you use?  Water or oil?


What kind of glass should be used?

We wrote up a method of determining Latitude both at sea and on land.
