EQMOD LST not matching local time

[Andrew INT]

Hi,

After (finally) going down the route of autoguiding, I have managed to control the mount via Stellarium, image through Sharpcap pro and guide (reasonably), through PHD2.

However, EQMOD reports the LST as about eight hours out! I have the correct coordinates entered, which also match Stellarium. Not sure how to resolve this.

 

I'm running (the HEQ5 pro) through the hand controller in PC mode.

Any help, greatly received!

Thanks,

Andrew

Andrew,

I use Cartes du Ciel, but the LST in EQMod should match that shown in your planetarium package. Have you checked??

Hi. Yes, the time in Stellarium matches the laptop clock.

OK, but do the calculated LST in Stellarium and EQMod agree?

My longitude is 0 7' 4.6" E so LST is going to be very close to UCT. Laptop clock shows 17:09, Stellarium clock shows 17:09 (not sure where calculated LST would be displayed), but EQMOD is still 8+ hours ahead.

LST does not (often) coincide with UTC. I'm at longitude 1.3 deg W, the current UTC is about 18hr but the LST is currently about 02hr.

Oh, I see. Thanks Seelive. I was thinking that LST was my actual local time. So, I can use the LST to judge what objects are crossing the meridian based on their R.A. (I think)

Thanks.
