Changing Targets didn't flip my calibration data on am5n

[Sushant Acharekar]

Hello

I was out shooting this weekend and some challenges like poor seeing and wind gusts but for the most part had relatively clear skies. I had set two targets the Jellyfish Nebula and the pinwheel galaxy . I ran the calibration assistant and started shooting the Jellyfish Nebula.

I use N.I.N.A and phd2.

When I started my sequence and it slewed centred and rotated to the Jellyfish Nebula  I noticed drifting in phd2 couldn't understand what was going, it never happened to me before so I restarted the mount did the calibration again and ran the sequence again and it started guiding as expected . However once it moved from the Jellyfish Nebula to the pinwheel Galaxy it started drifting again. I couldn't figure out what was going on . It looks like it failed to flip my Calibration data . I am suspecting something went wrong with the handshake between the mount and phd2. But I am not sure it would exhibit this kind of behaviour. Since then I have cloudy nights so I have no chance to test this again. But I for now have reinstalled the ascom drivers and have updated to the latest version of the drivers which were a version older. 

Any insight would be really helpful to know if I was doing something wrong .

I think we need to know more about your configuration, both the imaging scope/camera and the guider.  I'm suspicious that you've configured a rotator as part of your PHD2 guider configuration, yet the guide scope apparently has a focal length of only 200mm.  Are you using an OAG on the 200mm scope?  If not, the guide camera isn't going to move when the rotator orientation has changed - therefore, you wouldn't want the PHD2 calibration to change at that time.  I notice that in your last two guiding sessions - one on the east side of the pier and the other on the west side - the guiding results are consistent.  But in that case, the rotator didn't change its position.  Netting it out, if you are using a separate guide scope, you shouldn't connect PHD2 to the rotator.

Hi

Bruce

I don't use an OAG , my main rig is a 560mm and I use a different guide scope that is a 200mm with a zwo 220mm mini. I do have a rotator connected to the main rig. I'll check in my phd2 settings but I think the rotator was never connected to phd2 since I use a different guide scope. But I might be wrong. My other issue is I made a mistake buying a zwo 2600mm duo and I have to always ensure I am using my dedicated guide scope to be sure it's guiding using that. Is there a way to permanently keep that as my setting or disable the guide camera on the duo or rename it . currently zwo calls both the guide cameras with the same name. I'll contact zwo and see if they can release a firmware update with a name change on the guider for the duo? At the moment I have to put the cap on my main rig or switch to a narrowband filter to ensure my guide scope is what phd2 is using .

You don't need to check your settings regarding the rotator - it was absolutely connected to PHD2.  That's one of the reasons we insist that people submit their log files, the log files record what actually happened. As far as distinguishing between the ZWO cameras, open the gear connection dialog in PHD2 but don't connect anything.  Just to the right of the camera selection drop-down list, there is an icon that looks like a branch - click on that and it will show you the details of what cameras are available for connection.  If you can figure out which is the guide camera you want to use, select it.  This should be a one-time operation, PHD2 will remember the choice.  Of course, if the cameras aren't clearly identified, there's not much PHD2 can do. While you have the gear connection dialog open, click on 'more equipment', find the entry for the rotator, and change it to 'None'.
