hi sonotaco,
spending half time in Marocco with 2 stations I can't use ufoanalyser because there is no map of the Nord Africa. could you as for the precedent request from Ceres prepare a map.
The center point is AGADIR.
The last test with ufoanalyser and the ISS as target show a difference of magntitude value between the annoucemnt from heavens above and the value calculate by Ufoanalyser.
Have you an idea to correct, or is it possible to check stars magnitude with ufoanalyser ?
thanks for your help

It is pleasure for me to make new maps
Wait a few hours.

This is a difficult problem.
The definition of the magnitude of moving object on video cannot be uniquely decided.
Appearance (the image) on the result media of moving object depends on the object's velocity, exposure time, back ground level handling, color sensitivity...........
UFOAnalyzerV2 measures the light sum of both stars and moving object on a field image (1/60 or 1/50 second exposure time frame) by assuming they are stopping in the image. It will be defferent from its of still picture (with long exposure time) or peak hold image.
I don't know what definition Heavens above is using, anyway it should be carefully discussed.

thanks ypu for your quick reply,
for the magnitude I'll make more test as the sky is clear again
