A pure python3 implementation of skywatcher synscan motor protocol. Tested on SkyWatcher AZ-GTI mount and open-synscan project (https://github.com/vsirvent/Open-Synscan)

SkyWatcher made some of their code public in (https://github.com/skywatcher-pacific/skywatcher_open) even a C# !WinForm python interpreter application exist. See (https://code.google.com/archive/p/skywatcher/wikis/Programmable.wiki) but, been a special interpreter, python integration is limited. This project try to fill this gap.

From sources:

git clone https://github.com/nachoplus/pysynscan.git
python3 setup.py install

From pip:

pip install synscan

By defaults connection parameters are:

SYNSCAN_UDP_IP=192.168.4.1
SYNSCAN_UDP_PORT=11880
SYNSCAN_LOGGING_LEVEL=INFO

This values can be changed via enviroment vars:

export SYNSCAN_UDP_IP=192.168.5.1
export SYNSCAN_UDP_PORT=11880
export SYNSCAN_LOGGING_LEVEL=WARNING

Code sample:

import synscan
'''Goto example'''
smc=synscan.motors()
#Synchronize mount actual position to (0,0)
smc.set_pos(0,0)
#Move forward and wait to finish
smc.goto(30,30,synchronous=True)
#Return to original position and exit without wait
smc.goto(0,0,synchronous=False)

More code examples are in examples directory.

Several CLI (command lines interface) are provided:

synscanGoto 32 10
synscanTrack 0 1
synscanStop
synscanWatch
synscanSync 10 12
synscanSwitch 1
