Celestron Evolution mount pointed ota below horizon.

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.

Eeek, a scary moment! Have you updated the handset for the change from BST to GMT?

Just a bit! 😬 Using SkyPortal on my iPad the date, time and location are always current, so maybe not that unless they can clash somehow?

Has Skyportal updated recently? There was a bug in CPWI recently that cased a Starsense alignment to do the exact same thing. I wonder if Celestron have managed to replicate the same bug in Skyportal as well.

Ah, maybe, although I can’t recall when the SkyPortal app last updated. Sounds plausible.

Are you on the latest firmware?
There was some mention of "SSA Camera causing short run away slews" that was fixed in the latest (Sept 2020) release.

Must admit, I last updated the firmware towards the end of last year. I’ll get onto that as I should’ve been on top of it anyway. Thanks.

I’d certainly make sure the handset is correct. You might also check the official teamcelestron forum (free to join) for beta firmware

I’ll certainly be checking it out before I use it again, along with updating the firmware. Thanks.

      Celestron SkyProdigy 6 Mount lose part, disassembly guide anyone?
      By stevebty
      Good evening everyone
      I am looking at a SkyProdigy 6 telescope for a friend. the mount had a rattle/lose part. I partially unscrewed the casing and the plastic cylinder pictured below fell out. Anyone got any idea what it is or where is comes from. Looks plastic but can feel metal in the centre.
      Does anyone have a service manual or disassembly guide?
      Many thanks in advance
      Steve

      Can you help solve this mystery, please? Star Sense camera will not hold calibration with OTA after mount is rebooted.
      By StarGazingSiouxsie
      Hi,
      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
      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.

      C9.25 or C11 Scope difference? Advice?
      By Quetzalcoatl72
      I'm after a cassegrain reflector but I don't know which one to buy,
      I have a celestron c5 and it worked wonders for all fields, I now want the same but twice as powerful as my final upgrade
      I am looking at a c9.5 for £1350 or a c11 for £2000, My question is an extra 2.75" focal worth it for £750 more?
      I will likely purchase one this week

      WiFi problems with StarSense and AZ_EQ 6
      By Bigwings
      WiFi problems.  Cant get Celestron SkyPort WiFi  working
      Equipment
      New  Skywatcher             AZ-EQ6
      New  Celestron SkyPortal WiFi adapter
      Celestron  Starsense 18 months old but as new and just first installation.
      2 year old SkyWatcher WiFi module.
       
      Mount plus  Skywatcher works  perfectly well with SynScan pro.
      Will not work with Stellerium, or Sky Safari trying multiple settings get connection to wiFi but messages ….telescope not responding.
      Added  StarSense for Skywatcher which works with the AZ-EQ6.
      Advice received was that any Celestron plugged into the StarSense  aux ports should work so add the Skyportal dongle into an aux port on the Skysense  -Skywatcher adapter box
      Get the following error.
      Connection failure
      Celestron Skyportal can make a wireless connection to the scope but the scope is not responding. Make sure the scope is powere on and connected correctly. Also make sure you selected the correct scope type.
      Use Direct Connect………is selected.
       
      Any Ideas Guys?
