David,

The best option for your problem is to make your own “Local Latitude” Starfinder.
After making it and using it you will see, that this is the best homemade Starfinder that
is ever published on Navlist.
It is the Starfinder of Tibor Miseta, from https://sites.google.com/view/misetatibor/celnav#h.5pz9aojzt8bu

It is very simple to build, only a paper base and a rotor printed on transparency film.
For use on board laminated the paper base, it is the then waterproof.

It is a real analog computer.
How it works?
Turn the date to the 180° to mark on the outer degree scale.
With a alcohol based fine line pencil, mark a dot on the analemma.
Draw one line, about 3cm long, from your longitude to the center of the Starfiner.
Now you can use the Starfinder for that specific day.
For a later date, wipe out the pencil marks with a drop of alcohol and a tissue and
make mew markings.

You can read of:
The UT time ± 10 min for:
Morning Nautical twilight
Morning Civil twilight
Sunrise

Noon and the Altitude of the Sun at Noon for presetting your Sextant.

Sunset
Evening Nautical twilight
Evening Civil twilight

GHAAries for a specific UT time for entering HO249 vol1 if you need that.

It shows the Altitude and Zn of the Navigational Stars om your Latitude for specific UT.

It can also give info about the Moon and Planets but you have to mark them first with
info from one Almanac.

The only drawback (that has every Starfinder) you cannot use it as a planispere, because
it shows the view from heaven to earth.
For the rest the most perfect Starfinder I have ever seen on Navlist, and you can make it yourself.

Regards,
