Entering A Minus Value On Synscan


Recommended Posts

Hi all,

This is my first post on here and need some help. I have a skywatcher skymax 127 synscan az goto scope but have trouble with entering the GPS coordinates. Mine are 57.66 and -4.34 the problem is the minus value I'm not sure how to enter this on the keypad. Any help would be great.

Thanks

Minus us west. Plus is. east. You're 4.34 degrees west

You'll need to convert that into degrees, hours and minutes to be able to enter it. So it 4 degrees. 20 minutes and 24 seconds West

57 degrees 39 minutes 36 seconds north.

Hope this helps

With the Synscan handset you drop the seconds component so the coordinates become 004 20 W , 57 40 N

Perfect, thanks for the replies.

Your welcome. If I hadn't been a hill walker I too would have struggling with the minus number. But I still navigate with a map and compass, not a GPS unit. I'll leave that to my friends to guide us into the bogs. Lol.

Hi, another beginner here. I was trying to do exactly the same as the initial question regarding the minus value. I now understand that the minus value equates to West, thanks for that. What I don't quite understand is how 57.66 N & 4.34 W finishes up as being

Sorry, still learning.

There are 60 arc minutes in a degree (and 60 arc seconds in an arc minute) so...

57.66 N = 57 degrees, 0.66*60 minutes = 40 minutes
 4.34 W =  4 degrees, 0.34*60 minutes = 20 minutes

...forgetting the fractional minutes (which could be converted to seconds in the same way.)

For anyone else reading this needing for location input help.

If you find your location on googlemaps and right-click on it your long/lat co-ordinates will be shown, copy those and paste it back in the google maps search location box and it will show you the long/lat co-ordinates in both formats.  And for those who don't read manuals you swithc between W & E using the scroll up/down keys next to the numbers.
