Hi fred,
in fact, I'm still trying to understand, with an alt-az mount, the station is set up, starting in the south and horizontally.
We perform an alignment on 2 or 3 stars
.
I realize that I do not have the same coordinates on the software and the SHC.
so I checked the GPS coordinates in the software and the SHC, I am therefore wondering if my reduction calculations are correct.
I have a nema 17 with a 1/30 reduction and a 20 tooth pulley and the large one with 320 teeth ( 320/20 x 30=480 )
if anyone has an answer?
Best regards
Vincent
