Now we are getting somewhere!  Would it be possible to identify the three 
disks with images?  It is a little hard to identify which disk is which, when 
all three are in one image.

What I can see is the blue overlay from the 2102D on top, with the base from 
the 2102D made as a transparency.

What I cannot find is the third disk separated from the base of the unit.

By the way, I have not seen this arrangement before.  Maybe you could show a 
series of images, in a step by step arrangement.

1) Show the base disk, just by itself.
2) Then show the horizon disk, where 71W is visible so we can see how it is arranged.
3) Then adding the sky disk (I think this is a transparency of the base of the 2102D)
4) And then finally the blue overlay disk.

Best Regards
Brad

The set up as shown on my Astronomer. Hope you can read the Base Disk?
You DR. or yard at home. 45N,71W Feb 4 observer GMT 20:56.
There are 3 disk involved 1 Base disk(carries all needed information,)2 horizon Disk, 3 star disk.
Place the horizon disk on the base disk and rotate it to 71w.
Your sky and horizon is set up to your closest LAT & LONG.
Find &Read the GMT at Feb 4= 20:56 off the base disk.  You want to observe at 
GMT 8:38. The outer rim is GMT only.
Add 20:56 and 8:38 together= 29:34 subtract 24:hours  leaving 5:34.
Place the star disk on the disk and rotate Aries to GMT 5:34. Done! your sky 
is set-up.  It that easy and quick. Find the month & day, read the GMT add 
the Gmt that you want to observe, set Aries to that time.
Note the 20:54 is equal to the start (GMT 00 of the day for Feb 4.
Now you can advance time from 5:34 as desired 5:34 is really the observe time 
of 8:38. You can advance to any sky occurrence ,(rise set what ever you 
desire ) read the time off the base disk at Aries and subtract the Month and 
day time to get the GMT. Each degree equals 1 day and 4 minutes of time.
This simple use, was made to educate and attract the young.
The Astronomer was mad to teach Celestial Navigation.
The instructor if he looks close will see every item of his course of instruction.
