Can you help solve this mystery, please? Star Sense camera will not hold calibration with OTA after mount is rebooted.By StarGazingSiouxsie
Can you help me solve this mystery, please?
I have a 2020 Celestron 8" Edge Evolution Ltd Edition 60 Anniversary model. The OTA is carbon fibre and some of the artwork is different but for in tents & purposes it's a standard 8" Edge Evolution
The problem is, when the mount is switched off. the telescope will not maintain its calibration between Star Sense (SS) camera and the OTA. Please not I am not talking a SS alignment here - I'm talking about the calibration between the SS camera and OTA.
This is what happens - I will do a SS Auto Alignment and the goto will be out by some margin IE. way outside of a 25mm eyepiece. So, I then calibrate the SS camera to the OTA, re-align, and everything is working perfectly. The goto is more or less in the middle of a 12mm eyepiece. Next time I reboot the mount, I do my SS Auto alignment and the goto is way off again and I have re calibrate the SS camera to the OTA. Once I do that, everything works fine again. And so the cycle continues.
Have you experienced this problem yourself or do you have an idea of what may be happening? Before you offer your suggestions, please read this list as what I have done to try and solve this issue:
1. The tripod and OTA are absolutely level before booting up the mount.
2. Once I have booted up the mount, I enter time and my location, using GPS co-ordinates. I am extremely precise about this and am entering the correct time (and daylight saving as needed) to within 2 seconds. The GPS co-ordinates of my location as absolutely spot on as well - they are the same co-ordinates I use for all my telescopes and they are working perfectly. So this is defs not a time, date or location issue.
3. The SS camera is mounted perfectly It does not move at all. I have the calibration problem even after rebooting without moving the telescope's position at all.
4. I have even tried a new SS camera and handset. Exactly the same issue persists.
5. The handcontroller, mount and camera have all the latest updates.
6. The battery is working fine and holding it's charge perfectly.
As I mentioned earlier, once the SS camera is re calibrated, everything works fine and the goto is accurate. The problem only arises after rebooting the mount.
Any ideas, suggestions or sharing of similar experiences gladly welcomed, thank you.
I am hoping someone here may be able to offer some help or advice. I have submitted a support ticket with Celestron but I am still waiting for a reply and would really like to get this working ready for the next clear sky!
I recently brought a starsense but have not been able to use it because it comes up with the following errors,
Err: Model Num
The telescope model could not be read and initialization cannot proceed.
An unexpected error occurred that may cause the HC to not opperate normally.
When updating the controller and camera it finishes succesfully but when I check for new updates it proceeds to install the same one again and again.
I can still control the mount and I think the camera tried to do an alignment in my room.
I have a Celestron Nexstar 6SE.

I’ve been using my 8’ Edge HD on an Evolution mount for a couple of years now and I added a wedge to it a few months back. Using SkyPortal with StarSense I’ve never really had any major issues getting it aligned.
Last night I was setting up to photograph Mars and went through my normal procedure. StarSense took its images but, after confirming success with the third plate, instead of just winding up a bit and parking it proceeded to pitch the ota towards the north well below the horizon.
Fortunately nothing snagged. I skipped the ASPA and instructed it to goto Mars and was surprised to find it was spot on (better than usual actually).
Anyone any ideas why it took that nose dive? Thanks.
Q. When using Star Sense, why does my telescope go all around the houses on some of its GOTOs? I'm sure I set 'Cordwrap' to 'OFF'??!! A. Because Star Sense reset it to 'On' after you did your alignment.By StarGazingSiouxsie
Now, I know that Cubble likes to keep fit. I try to keep all of my telescopes healthy and feed them only the best planets and DSOs.
But - why is that Cubble just LOVES to go all around the houses on some of his GOTOs?! Talk about taking the long way home!!! I could have sworn that I had 'Cordwrap' set to 'Off'.............
I have set Cubs up with a totally cordfree / wire free system and therefore find this going 340 degrees around to an object that is 10 degrees away incredibly annoying and time wasting.
Well, I think I may have found the answer today. Some of you may already know this but for those that don't, I hope it helps relieve some of your frustration.
What I disovered is that the Star Sense hand controller resets the Cordwrap setting (MENU>>>TELESCOPE>>>CORDWRAP) back to 'ON' each time a new alignment is completed. So, one can spend time seemingly making sure that it is set to 'OFF' (if that's the setting you want, of course) only to find that once you have completed an alignment, the hand controller defaults the Cordwrap setting back to 'ON'.
So, if you don't want or need Cordwrap set to 'ON', make sure you change the setting after completing each new alignment.
