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.
Hi... Hope this is ok to post here.
I've built an app to create star trail images and videos using an iPad or an iPhone and i'm really struggling to find beta testers.
Check out the photo and video I've added to the post to see what it can do and and click the link if you want to try it out.
https://sites.google.com/view/starstackerforios-beta/home for info.
https://testflight.apple.com/join/7iLGfVDG to get the beta.
It's free to have early access to the beta. I'm just hoping to get a bit of feedback before it releases.

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.
A week or so I good I did some preliminary research for a decent 32mm eyepiece. Looking at my results today I went for budget but decent.
I have ended up with a shortlist of: -
Revelation 32.0mm Plossl Eyepiece 1.25"
Celestron 93323 1-1/4-32 mm Omni Series Eyepiece
Baader Planetarium 32 mm Classic Ortho Eyepiece
My query today as I recheck my findings is the Revelation one. That is coming up at almost half the price of the other two (at www.telescopehouse.com)
But this eyepiece made my shortlist due to positive comments about the GSO build.
So, finally, my question, does the purchase price suggest this 32mm isn't a GSO?
No rush here. It's a wish list not a need list - as I remind myself... lol
So the little circular bubble level is weak.
But how to improve the levelling stage a head of the alignment stage?
A traditional level like this one
Or a simple multi purpose one like this one?
And we do this on the tripod before adding the mount & OTA?
The mount looks gently curved. How do we check that for level or do we trust the ‘fit’?
