Download		 ※The values of Parking 1 and Parking 2 will be changed through this update. If you have entered any values, please move them to Parking 3 and Parking 4 before updating.

– Fixed a bug where the RA axis suddenly rotated when the mount is pointing the North Pole (or South Pole, DEC value 0 or 360)
– Parking 1 -> Change to “Default”
The value is automatically set according to the mount type and southern/northern hemisphere
Equatorial Mode, Northern Hemisphere-AZI 270, ALT 0
Equatorial Mode, Southern Hemisphere-AZI 090, ALT 0
Alt-Azi Mode, Northern Hemisphere-AZI 180, ALT 0
Alt-Azi Mode, Southern Hemisphere-AZI 360, ALT 0
– Parking 2 -> Change to “Polar Axis”
Only works after mount homing
Pressing the ENT key on the screen causes the mount to point to the North Pole in the Northern Hemisphere and the South Pole in the Southern Hemisphere.
Used when aligning the polar axis with ASIAIR, Sharpcap, Stellamate, etc.
– Change the Meridian Limit input value from two to three digits
