Profile was lost

[Ed Chavez]

I must have not saved my profile when I made a new profile for a new guide camera.  I think my settings may have been deleted.  In any case, I got multiple settling failed messages.

So, I had to put my old guide camera on after my new one failed.  I attempted to restore the old profile so I would not have to run calibration again.  But now, something is going very wrong with both the DEC and RA way off.  Please help.

If you alter the guider hardware in any way, a fresh Profile must be created. So, removing and later replacing the same guide camera means the New Profile wizard needs to be used again.

Yes, you can simply create a new profile and re-calibrate in less time than it would take us to pore through your log files trying to reconstruct what you did wrong.  In the end, you would just have to build a new profile and calibrate anyway.  Use the new-profile-wizard to create the profile and then use the Calibration Assistant (Tools menu) to get a calibration.  Don't give up on the calibration process until you get at least an 'acceptable' result.

Good luck,

Bruce

I didn't alter the guider profile, I simply swapped the new camera(with it's own profile), back to the old camera and re-imported the saved profile for it.

The reason I do this is because calibration is a major hassle for me as I don't have a view of the southern sky.  I order to get a view of the southern sky, my whole setup has to moved downstairs and to the other side of the house. So, no, it would take much more time.

Ed you don’t have to calibrate at exactly that sky position. It’s ideal but you can calibrate rate elsewhere provided you avoid the poles. The closer to the meridian/celestial equator the better. You can just slew the mount to where you do have visibility to stars and then click calibrate in the wizard

I'm sorry but that’s the way it is.  You can do a calibration wherever you have visibility unless it’s only at the celestial pole.  The accuracy may be sub-par but you can try it. You can’t switch equipment around willy-nilly in the same profile and if you do, you will always have to recalibrate.  PHD2 doesn’t “lose” profiles or delete them unless you specifically tell it to.  I'm afraid you’ve gotten yourself into a mess here and I think you will have to get yourself out of it, there’s no magic way to repair whatever it is that got fouled up.

OK, I guess I was aware of that but under the mis-impression the accuracy would suffer significantly.  I would guess if I calibrate to the North where I can see, if I am close to the meridian, I will be within 30-40 degrees of the celestial pole. 

[Ed Chavez]

Bruce,

As I said, I am not switching equipment under the same profile.  So, are you saying I'm in a mess by looking at the log I provided?  I will try to create a new profile and calibrate under the less than ideal circumstances but I worry this will not solve the issue, unless you are telling me the log says my calibration is the source of my issues.  Thanks. 

[Bruce Waddington]

The log shows that PHD2 couldn't control the mount effectively on either axis, the errors are huge.  One possibility is that the camera is now rotated relative to where it was the last time you did a calibration (5+ months ago).

>>>   I would guess if I calibrate to the North where I can see, if I am close to the meridian, I will be within 30-40 degrees of the celestial pole. 

it sounds like you are in a bit of a pickle. picking up and moving your mount to calibrate, then (presumably) moving it back to image is probably going to compromise your calibration. 

But it also sounds like you have limited visibility in general. 

Do you have a horizon map you can share?

When you calibrate, the most important thing is to avoid the celestial pole or being near it. If you can point east or west away from the pole but at a reasonable altitude that can work as well.

I have a custom horizon file for NINA but not for PHD if it has that ability.  But yes, I'm very limited in my horizon due to where I live.  

Thanks for the tips on calibration.  I will have to calibrates about 20-30 degrees away from the meridian to a reasonable altitude I think.

The horizon was more to get a screen shot to see what your open sky looked like
