hi everybody. i bought a digital setting circles system from astro devices (thanks serge) had it around 3 years now but it seems to of lost its accuracy when using skysafari pro version 5 on android, i also bought originaly skysafari pro version 4 and its the same with this. had a phone call from serge at astro devices and he suggested that i use the astro devices utility to check that all is ok with my system.
the test was. set the scope up 20" f4 dobsonian and use some kind of indicators to mark alt and azy i used sticky paper and marked a line on each section so i could return the scope back to exactly the same postion and check that my encoders were correct.started the utility and zeroed the encoders. spun the telescope in all sorts of positions for around 15 mins came back to the original rest place and everything is perfect. tried lots of times and each time it returns the same answers. perfectly aligned with all markers and zero on the utility.
but when i align using sky safari any version the alignment is out within around 10 mins of use, the only way i can explain it is. the night sky is moving wrongly in sky safari. can somebody please help. this has been very frustrating over the last 6 months and frankly embarrising when i endorse both products so much. thank you and sorry for the long message
