Re: Suddenly stars are dashes with good guiding

No, not ground moving, very solid on concrete or attached to a pier. See other response, most likely loose front ring on guide scope. A while back after an unrelated but similarly vexing but simple problem, I resolved to prepare a checklist of all possible things that could go wrong on various parts of my rig. It would be similar to the one pilots pull out after an engine quits. If I had such a checklist, I probably could have saved a lot of imaging time since, "check guide scope ring tightness" would have been somewhere on the list. 

Probably should follow through with that idea. I'll add "did ground move."

I don't know if it's relevant, but both times it happened at around the same elevation, around 50 degrees under warm, muggy conditions thanks to our current heat wave. I had planned to gather a bit more data last night, shut off guiding to check for obvious drift, save some example frames, and a log file.

I'll bounce this off the PhD forum and maybe the brain trust on Cloudy Nights if necessary. But I wanted to exclude anything obvious other than guide performance that might cause it.

Others will weigh in, but modeling in APCC as I understand it, and it's on my list of things to implement. My imaging set up moves around a lot though, so I don't know how often it will be practical.

Would it not be easier just to move the file to another folder, say /APPM-PNT-Backup/?  Then you do not need to worry about editing and the file could be easily moved back and restored to APPC, if necessary.

Loose front ring sounds like the culprit.

Yes, certainly not the mount. Focuser is tight on both main and guide scope, cables are routed and bundled as they should be, guide camera is tight and focuser/guide bracket are tight. BUT, the front ring on the guide scope was a bit loose! And, yes, I have an off-axis guider on that camera and it works great, but I've been switching between a dslr and the QSI, so using the guide scope is one fewer thing to redo when switching. I should switch, duly noted. 

I suspect it was that slightly loose ring that was causing the guide scope to wobble. If not I'll report back, but I think that solves it. I might have figured that out, but this prompted me to figure it out faster.

Thanks,

Re: Suddenly stars are dashes with good guiding

Hi Chris,
Yes, any slop in the guide assembly, e.g. mounting, camera, focuser, etc., can lead to differential flexure and it can be a real pain to isolate and fix. You mentioned that it appears in the same portion of the sky, so I’d be looking for gravity kicking in at that pointing location, as that may be the straw that’s breaking the camel’s back. Good luck tracking it down.

Have to admit I didn't think of that, but am aware of the problem. I broke everything down and reinstalled the guide scope between the two sessions. I typically tighten those guidescope mounting screws good and tight, but that's another thing to check. I wonder if the mounting screws on the focuser itself or the guide scope mounting bracket have worked ever so slightly loose? That would cause the same issue. I'll check that too. Thanks.

Re: Suddenly stars are dashes with good guiding

If your guide scope is held only in 2 places, you will get differential flex. Needs to be held in 3 places. Take a look how we mount a guide scope:

Re: Suddenly stars are dashes with good guiding

If your guide is good then the mount is doing what it's supposed to. That does not mean that your imaging scope is doing the same thing. Remember, the mount responds to the guider, not to the imaging scope, unless you use an off-axis guide system.

Some things to look for: Focuser moving sideways during an exposure. Cables from camera getting bound up and pulling on the camera. Differential flexure between main scope and guide scope. Guide scope focuser not fully supported in at least 3 spots 92 is not enough). Guide camera shifting during the exposure.

Only way to always have guiding work is to use an off-axis guide system.

So, I have experienced an odd problem, to me anyway, the past two nights of imaging.

I have used basically the same setup for a year and a half since I got my 1100AE and before with other mounts.

Re: Suddenly stars are dashes with good guiding

Geof Lewis
 

It sounds like differential flexure to me. Have you check that the guide scope hasn’t worked loose from the main OTA, it won’t need much and you probably won’t even see it. Guide performance may well be nigh perfect, but if the guide scope is slowly shifting about then you’ll see that in the images taken through the main OTA.

Good morning,

Using my Mach1 and APCC-Pro/APPM I took this image over four nights without guiding.  I used a Takahashi FSQ-106EDX4 and modified Nikon D800e to collect about 7.5 hours of sub images.   The ability to image without guiding is amazing.  Thanks to all the folks at A-P for making such nice instruments!

Re: how to clear APCC/APPM model

 

Thanks Ray

what about the sections

<WestPointingModel>
and
<EastPointingModel>

that follow the <PointingModel> xml?

1. Shut down APCC if it isn't already.
2. Edit the file "C:\ProgramData\Astro-Physics\APCC\settings.apcc" with notepad or other editor.
3. Locate the and delete the lines starting with <PointingModel> through to </PointingModel> (inclusive of those lines).
4. Restart APCC.

Brian,

Ray's solution is probably better than mine, although you might consider doing both. Here is an example of the lines to delete. Yours may differ slightly:

<PointingModel>
<EstablishHome>5</EstablishHome>
<LoadFile>C:\ProgramData\Astro-Physics\APCC\Models\ApPointData-2018-09-11-201350.pnt</LoadFile>
<FormTop>25</FormTop>
<FormLeft>25</FormLeft>
<FormHeight>870</FormHeight>
<FormWidth>1254</FormWidth>
</PointingModel>

Brian,

Is there a way to completely clear an APPM-generated model from APCC?
1. Shut down APCC if it isn't already.
2. Edit the file "C:\ProgramData\Astro-Physics\APCC\settings.apcc" with notepad or other editor.
3. Locate the and delete the lines starting with <PointingModel> through to </PointingModel> (inclusive of those lines).
4. Restart APCC.
