Hi Bert,
My friend (Ritchie-I) reported issues with tracking, he indicated tracking is too slow.
It seems I have similar problem with my Dobson after upgrade from Bartels system (which was running perfectly OK for the last 20 years on Fujitsu Stylistic 1000) - I decided to change because OnStep is somewhat simpler to operate (using mobile as handpad)... tracking speed looks like 1/2 of what is required, objects (Sirius) is visibly moving westwards.. I suspected wrong local time was set during init, but my phone says correct time was sent (GMT+10.. and we still have Dls).
Did you do something else we should be aware of?
Thanks in advance for your help
Bojan
