I did some code cleanup. It would be great if you test the current version.

Detecting slewing and tracking state was still not right. The problem was, that guiding signals - which typically show up as motor status 4 - resulted in a state SCOPE_SLEWING, which was definitely wrong. As a result, PHD was interrupted frequently.

I changed it now that way that ReadScopeStatus() never sets the state SCOPE_SLEWING on its own but it detects, when a slewing state has finished and results into tracking, a parked scope etc.

Please pull the latest version of the ken-self-sync branch.

OK, the fix is published, please pull the latest version of the ken-self branch .

@kengs: I had forgotten to commit the changes for the info messages. Now everything should be in place.

Ouch, you are absolutely right. I will fix it today.

That's right, this message was missing in your branch. I did some changes on top of yours. It found that parking/unparking wasn't behaving correctly and that I could slew a parked scope. This should be fixed now. And I re-introduced the messages about a slew complete which I find an important message.

So it might be that the mistake was introduced by my latest changes, right.

Hi Ken,
here comes the log file. Please take a look at the entries after 2018-10-03T20:36:10.872, where I started the EKOS polar alignment routine. After the first solved frame, the scope is sent to RA: 07h 59m 17s, DE: 88° 19' 45. At 2018-10-03T20:37:16.470 CEST, the telescope reports that the slewing has completed and a new frame is taken.

What we cannot see in the log file is, that in fact the slew wasn't complete. We can see it only indirectly in a failed solving attempt, which comes from star trails in the taken image.

Currently, my M-zero is in action. I will investigate this tomorrow.

Cheers
Wolfgang

Folks, I found an error last night in the ken-self-sync branch that the mount does not correctly report when it is slewing and when slewing is finished. This leads to problems in EKOS where a plate solving for example is started too early while the mount is still slewing to the expected target.

Please use stargo_work , which does not show this behavior.

Ken, many thanks for your changes. Meanwhile I found the time for a first test, everything seems to work properly.

I introduced an intermediate branch to ensure a safe merge into the main branch. For those interested in the latest changes, please use the ken-self-sync branch .

@DrGkill: I am already in contact with the Avalon development, so let's use this channel.

Sorry folks for my bad responsiveness. I was on holiday and I have a massive pile of frames to digest. Still not finished...

@DrGkill: could you please upgrade your StarGo firmware to the latest version (now I know how Microsoft feels :-P) .

Sure. You can get the sources from Github.
github.com/sterne-jaeger/indi.git
Please checkout the branch named "stargo_work". In this branch you will find the sources under 3rdparty/indi-avalon.
You need to compile the sources as described in Readme.md in two steps:
- build libindi and install
- build 3rdparty (I would do it entirely) and install it.

Hope that helps
Wolfgang

Sounds good. It would be great if you create a pull request - or simply send me your modifications directly.

Have you already turned on logging to file? With debugging turned on for the Avalon driver, you could find the entire LX200 communication in the log file under ~/.Local/share/kstars/logs

Wolfgang Reissenberger replied to the topic 'Re:Precise autofocus' in the forum. 2 months ago

The FSQ-85 has an integrated flattener. The problem is, that the flattener requires a perfect focus. A minor de-focus leads to oval stars. But with exact focus, the result is impressive.

OK, I will give it a try with longer exposure times. The problem is - exactly as you describe - finding an acceptable low tolerance with the given seeing. Currently 5% works fine on my TSA-120, but this scope is much more tolerant.

Wolfgang Reissenberger created a new topic ' Precise autofocus' in the forum. 2 months ago

My FSQ-85 is very sensitive in terms of focusing. Even slight defocusing ends up in oval stars in the corners. Fortunately, the direction of the ovals indicates in which direction I need to shift: tangential ovals are shown in the extra-focal position, radial ovals indicate the intra-focal position of the focuser.

Currently, I use the autofocus routine only for coarse focusing. Afterwards, I need to correct the focus manually until I see round stars in the corners. With the autofocus routine I am not able to reach a focus point that is precise enough.

Any hints, which parameter setup I need to choose for the EKOS autofocus routine so that I can avoid a final manual fine tuning?
