Onstep total beginner question #EQ3 #bluepill
Francois94
Hello all ,
as a total beginner in Onstep , and generally speaking in goto , i have certainly a stupid question : Assuming my onstep conf is ok , north hemisphere, lat/long , utc offset , date&time correctly documented , mount tuned to the good angle and pointing the north ,home position set . If i stand in front of the mount , counterweight just in front of me , and i push the right button on the SHC , should the RA axis turn clockwise or anticlokwise ? Same question for the DEC , if i push the up button , should it turn clockwise or anticlokwise ? This question may looks stup for lots of you , but on my side , doing a lot of tests during the day as the weather is really horrible , i'm often changing time to simulate a later one and match with stellarium and sometimes , pushing the same button on the controler launch the mount in one direction and sometimes in the other so i'm a bit lost . I've understood that for goto , it will calculate the "shortest" path to the target , according the current position so i can start on one side or opposite , but for manual operation , i don't really know . Thanks in advance for reading me and answering my newbie question .

There is no answer for this other than "it depends." It depends:

Here is my setup and indeed , if i stand south of the mount , pushing the 3 O'clock button , the RA axis is turning CCW:

Looks good. Your RA drive looks well designed. Are you using a printed motor mount?

Yes , design comes from Frank in that topic : https://onstep.groups.io/g/main/topic/my_skywatcher_150p_on_an/83327227?p=,,,20,0,0,0::recentpostdate%2Fsticky,,,20,2,120,83327227
I just made some minor changes to improve stability as the RA mount is only fixed
