EQMOD/Carte Du Ciel - Slews in opposite directions for east and west


Recommended Posts

Hi All

I hope someone can help.

I’m having a bit of a nightmare with EQMOD and CDC slewing my telescope in the wrong direction. I ask it to go east and it goes west and vice versa. However it parks fine near Polaris.

I have just started using a new laptop to run the mount, it worked fine with my old laptop a couple of months ago. I have installed and uninstalled and re-installed CDC, EQMOD drivers etc but still it slews the wrong way !

I have checked the location info, date and time etc.... they are correct and identical in CDC and EQMOD . The reverse RA/reverse Dec tick boxes in EQMOD are un-ticked.

I have a feeling I am overlooking something obvious here ?

Hello everyone

I spent hours scratching my head with this yesterday. Today I woke up looked at it with a fresh head and found a problem and solution (I think ?). I'm posting it here in case anyone has any thoughts (is this the correct solution ?) or anyone else comes across similar issues .

Ok....What I didn't notice in the daytime yesterday was that east and west were actually reversed on the CDC map itself, because it was daylight I was just clicking on things I assumed were on the east of the CDC map to see if the telescope would go in roughly the right direction, it always went in the opposite !

Today I looked again and where I expected east on the map it said west and vice versa. A look through all of the settings and I found chart/transformation/mirror horizontally. I clicked this and the chart flipped, east and west were now where I expected them to be. A quick plug in to the mount and it slewed in the right direction. Problem solved I hope ?

Sure this was just a bit of a schoolboy error not noticing that east and west were reversed on the map itself, in my defence it was daytime and I was just clicking on random stars to see the mounts direction !
