Poor goto's when using eq mod but fine with syn scan???

[White Rabbit]

Hi guys.

Wow, Have I been having problems with my set up of late.

My latest is poor goto's when I use eq mod on my heq pro 5 (wonder why they put a pro in the name ,) but fine when I use the hand controller only.

Goto's are out about 3 deg, but in some parts of the sky it's fine. Polar alignment is good so it's not that, it's not the cable as I got a new one on the weekend. I've even reinstalled all the software. I've checked the day light saving is correct, time is set via the Internet.

I have a lot of Dec backlash but it's never been an issue before and it guides fine (after a lot ot faffing around during the week) I'm stumped. Can anyone shed some light???

Thanks
Sandy

I once had similar problem and it was due to the lat/long entered being different in EQMOD and planitarium software.

Thanks I'll check that.

If that doesn't work check to see if any alignment points are getting loaded when you open EQMOD. You might have a bad point or two.

Were you using the same alignment stars as the HC? I think (but don't quote me on this) the algorithm used is different between EQMOD and the Synscan controller. Assuming they are different, one would expect a slightly different result? I know I wouldn't expect that but it could be possible. When I was using EQMOD a couple of years ago, I found one star alignment enough when the mount was properly aligned.

If you are a member of the EQMOD yahoogroups, have you put the question forward to them?

Good point. Do you use the H/C at all? If you do, don't. In my case mine is back in the box, and I use CdC and the EQDIRECT cable only, nothing else. Like Andrew, normally one star is good enough.

There are some good tutorials on youtube:

And this one in particular that goes through alignment:

Had a similar problem. Eq5 eq mod stallerium. was sending me crazy. Wasted all night at Wiruna one night trying to get goto. Out about 3 deg every time. Finally figured it out. Once you unpark your mount you can hit "reset sync" and " reset align star data" in eqmod. Then perform your goto on two stars. Should be fine. Remember to only reset AFTER you unpark!
