Good job Bob

Just some thoughts since you're very interested in celestial navigation..........As I’d mentioned previously, FN probably would have used stars at an azimuth of between perhaps 30 and 210 degrees and an altitude of between perhaps 6 to 60 degrees while taking shots out the windscreen and right side window. The Electra didn't have an astrodome like planes developed later, where the navigator could look around 360 degrees and even dircetly overhead, so he was probably restricted to both azimuth and elevation of the stars, planets, sun and moon that he used. Although the moon was available up until around 1400GMT, since it set in the west, most likely they wouldn't have turned back for a moon shot.
Here are a couple of shots I’ve taken during test flights at 1700 and 1800 UT (GMT) using the planet Venus and the star Achernar.
Celestial Navigation Data for 1937 Jul 1 at 17:00:00 UT
For Assumed Position: Latitude S1* 03.0’, Longitude E175* 35.0’
Object, Hc , Zn
VENUS +12 52.7 , 71.7
ACHERNAR +28 11.2 , 160.0
Second Star shot 1800GMT Celestial Navigation Data for 1937 Jul 1 at 17:50:00 UT
Latitude S0* 40.0’, Longitude E177* 10.0’
VENUS +26 29.1 , 70.0
ACHERNAR +31 20.8 , 167.6
These two star shots fit the criteria for acquiring a fix by being near 90 degrees apart, which is what we’re looking for. Notice that the vertical and horizontal lines are nearly crossing each other perfectly. That’s what we’re looking for when taking more than a Single LOP shot.
I wonder if you've tried Teson1's RE (realengine). I believe it can be used to modify the Electra in FSX as well as FS9
I hope you are having a great time at Oshkosh
