Re: Mach1 Unable to Find Home Position Suddenly


So , to be clear, if I am out in the field and using my CP4 and hand controller with the older firmware (not mach 2 new) and I am using an older atlas that has J2000 coordinates I need to convert them to JNOW before entering on HC? Be kind, you are dealing with a pilgrim here. Tom FIscher, Indy

Hi Mikko,

The mount's coordinates are JNow. And it does make a difference.

Well actually my original issue is still unsolved, meaning the Platesolve not working out of blue after being
flawless for years. What I do see is that the mount coordinates don't match the SG Pro coordinates. Further I don't
know if AP V2 uses J2000 or JNow and if this makes any difference. I've asked the same question from the SGP
developers but didn't hear anything constructive back yet.
