    Hello,


    I had been imaging with my STX-16803 for a few months before I swapped it out for a different camera. It had been operating just fine then. After setting it back up on my scope tonight, I have frequently been running into "camera error 17" which I understand to be an issue with the shutter. The shutter had given me no problems before I put it in storage for a bit.

    Interestingly, power cycling everything and re-seating all the cables (with the power off) caused it to "work" for about 5 frames. I don't know how well it actually worked though, as I was chasing focus after re-installing it on my scope (but at least it generated a FIT file). It then started to throw the same "camera error 17" after those 5 test images.

    Additional diagnostics:

    MaxIMDL version: 6.40

    CCDOps give a similar “shutter error”.

    Video of what it sounds like when I try to image a couple of times: https://www.dropbox.com/scl/fi/p6ma...1-PM.mp4?rlkey=xhlpzmf7pmyu48n7a62wns8dp&dl=0

    The buzzing sound is its idle sound (though I don't recall it being that loud), and then the silence is when I hit “Expose – Start” followed by some deeper jittering around sounds.

    Computer restarted multiple times, as was the camera; no issues in the Windows Devices app.

    It's also 10F here at the moment, but I don't know if the temperature would have much to do with the issue.

    Guidance on how to proceed would be much appreciated. Eg. if there's a way to manually, or via software, cycle the shutter to see if the mechanism is at fault, please let me know how.

    Thanks,

    ~David

    Oddly enough, the guide camera also experiences error 17

    And just to add another layer of issues:

    1. On the rare occasion that the shutter doesn't throw an error, there is a weird artifact consisting of a bright line under the brighter stars (Which doesn't go away if I use the RBI flash). See attached.

    2. Apparently I can't use the main camera and auto-guider at the same time. If I start looping on one, the other's option to image is greyed out. Attached is what it looks like after starting guiding: no way to use the main sensor to image. Did I set up the sensors incorrectly? The guide chip is set to "external remote".

    Normally I'd ask for FITS frames... but this looks like very much like a sticking shutter.

    Make sure that the screws used to hold the nosepiece adapter plate on aren't too long - this has occasionally been an issue when people don't use the original supplied screws (or mixes them up with other screws).

    Failing that, you may need to send it in for service.

    Be sure to check "Dual Chip Mode", on the Camera Control window "Setup" tab.

    @Doug, I'll be sure to check the screws; no idea if they are the original, as that's just what it came with when I got it 3rd(?) hand. Two questions: 1. How does sending it in for service work? Any particular requirements, and which address to send it to? 2. Are there fixes that I could try (eg. some tension screw needs adjusting, mechanism oiled, or the like)? I imagine that would be more expedient if it's even just relatively straightforward to fix.

    We have a standard RMA process. @Tim can help you with that.

    Whatever you do, do NOT try to fix an STX shutter issue yourself. They have to be set up very carefully.

    Gotcha; I'm coming from SXCCD cameras, which have a fair bit of user-serviceable parts. I'll be sure not to touch the SBIG.

    I'll wait to hear from @Tim about the RMA

    @Tim , I haven't followed up since I decided to wait until the weather was warmer and try again. Lo and behold, I haven't experienced a sticky shutter once when the weather is ~20F or above. So I think I'll just keep using it as is, and be judicious in trying to image in very cold weather.
