Yes i tried various configuration....but It seems It doesn't receive any signal. I tried also different stepper drivers like drv8825, lv8729 and tmc2130. Nothing. It doesn't move

My purpose is to replace the basic hand controller. I would use it only with planetarium software. Right now I am visual observing only. It would be used to fine tune the goto after slewing. Other functions would be accessed using the Android app.

Speaking of the Android app. It would be nice if I could use it in a "demo" mode without any connection. Having it lock up when it doesn't find a connection prevents me from previewing the screens and functions.

The microstepping for Axis3, 4 and 5 is not set in the configuration.
It is determined by jumpers on the driver in question on the board.

You may need to adjust other parameters such as microns, ...etc

P.s. i connected focuser motor in the same way i connected axis 1/2

Another note about this gamepad ...

The number of keys match what is on the SHC, though in different placements.
So in theory everything the SHC does can be mapped.

But the big obstacle is that it has no display, and therefore you need to rely on
some other component such as a planetarium. Even simple things like starting
and align, or slewing to an object will be challenging.

Mount now finished final pictures added on Stargazers.
https://stargazerslounge.com/topic/337103-vixen-porta-mount-ll-onstep-install/
I have now used the mount at two sites and making level and pointing north works great . The battery that I have at the moment starts to loose steps after about an hours use and results in stalls as the voltage drops slightly ,  so I will get the next size up .
Very happy with the final result.

Thank you, I thought I saw something but I am definitely suffering from information overload at this point. Enough of my hardware came in to breadboard my MaxESP2. Got it working but the servo wire order seems weird, I'll start another thread.

I have read some of your warnings about the Bluetooth library issue. I am forewarned. This is the reason I chose the MaxESP2. Two cores means one can handle the Bluetooth (in theory). Your using the Wemos mini wifi offloads that function nicely. My idea is to connect my laptop and planetarium program (not settled on one just yet) using wifi and use the Bluetooth for the gamepad.

But first I need to get the existing implementation (using the ST4 wired basic hand controller) working on one of my scopes.

No one that I know of, I thought about it before the SHC existed but never did anything about it.  Watch that MaxESP2 and ESP32, the built in Bluetooth only ever worked for me with the Arduino ESP32 libraries version 1.0.0 and then only when the patch I outlined is used.

Haha, I'm taking a break from tinkering on this thing. It's been non-stop for 3 months. Now that I can actually gather light with it I'm going to put the few things I still need to do to it on the back burner. I somehow bent my coma corrector by over tightening the focuser on it so that's the next must-fix issue. I'm still on the journey, just going to slow down a bit.

Very nice image.

Also 20 minutes on the elephant trunk to see if it would show up. Should be able to do a good job on that one too.
Is that a single exposure or a stack? Looks from the graininess that is the former.
Is the camera modified for Hydrogen Alpha?

Don't forget the Crescent Nebula while you are in that area ...

Hmmm ...

That is not how it works. You need to get with the program ...

For us, the journey is more important than the destination.

We get to use our rigs for 2 or 3 days a month. The rest of the time? We keep tinkering with it,
be that updating the firmware, trying different configurations, checking used equipment on
various classified ads, post here and on Cloudy Nights, ....etc.

It is like that neighbour that keeps busy tuning his car or motorcycle, adding features to it,
buying parts, ...etc., only to drive it occasionally.

Or maybe that is only the subset of us who have polluted skies and lousy weather ...

Nice images by the way.

Re: 2-3 star alignment.

Khalid Baheyeldin
 

I don't have a specific answer for your question, which is vague. Are you asking specifically
about when the mount is not leveled correctly?

But here is some info:

The first star alignment just brings the celestial sphere and the internal coordinates
together.

Internally, OnStep calculates the following errors:

  ax1Cor=0;  // align internal index for Axis1
  ax2Cor=0;  // align internal index for Axis2
  altCor=0;  // for geometric coordinate correction/align, - is below the pole, + above
  azmCor=0;  // - is right of the pole, + is left
  doCor =0;  // declination/optics orthogonal correction
  pdCor =0;  // declination/polar orthogonal correction
  dfCor =0;  // fork or declination axis flex
  tfCor =0;  // tube flex

The altCor and azmCor are the errors in Altitude and Azimuth (mount not perfectly
aligned with celestial pole). To calculate these, you need at least a 3 star align. So,
this is the minimum number you should use for accurate gotos.

The more stars you align on, the better the alignment. All boards offer a 6 star align,
and you can increase that in the Config file (at the expense of a couple of minutes
of slowness while the calculations are being done).

Re: Some bright alignment stars don't show up in the Onstep app

simingx@...
 



In other words, apart from starting an alignment, I don't use the Android App for the actual alignment.
Oh! I didn't know that Skysafari could do that too! That simplifies matters greatly, as I don't have to look up where the stars are :) in fact I just tried it and indeed the App proceeds from the 1st star to 2nd and so on after I click "Align" in Skysafari :)
