mount:  AZ  motor drive:  no

Timing&recording:
Sensor:  Visual
Recording:  NTP  stopwatch

Observing conditions:
Atmospheric transparency:  Very good
Star image stability: good
Wind:  1 km/h
Temperature:  +13
Minor planet visible:  No

Commend:
I started the stopwatch exactly according to the NTP clock on the computer and determined my error =0,0"
Observing star poisoning, I rate my error as lag =0,2"
Observing star discovery, I rate my error as lag  =0,3
Having the stopwatch readings I calculate taking int caccount my personal error and the result was given as calculated, i. e. correct.
This is my first positive observation
