BUG - ASCOM Interface Through BYE Not Working - 3.1.18 RC11

JTWaters · November 3, 2019

I decided to test the ASCOM Telescope user interface through BYE Rel 3.1.18 RC11. The DEC slew buttons do not work. The RA buttons work as expected. Everything works through the standard Telescope.NET interface and the Gemini-2 HC.

ASCOM Rel 6.4 SP1
Losmandy GM811G - Gemini-2
ASCOM Gemini Driver 1.0.72.0

Where do you hide the log files?

Hi Jim,

I got your log files. BYE uses the MoveAxis command the move the mount. Looking at your log files your mount/ASCOM driver supports those command. That is good.

Going further, I'm correlating the BYE log file with your Gemini log file. Each time you press a button in BYE (both RA and DEC), I see the corresponding IT:MoveAxis command in your Gemini logs (within a few milliseconds) so BYE is sending the command and Gemini does get them. According to BYE the command was sent and the ASCOM driver has received the command and past it along to Gemini... and Gemini did not return any errors so at this point BYE assumes the mount has moved since no error were reported by ASCOM/Gemni driver.

Do you know if the your tests through the standard Telescope.NET interface and the Gemini-2 HC uses the MoveAxis command to move the mount? If not that may explain why it behaves different.

Regards,

Hi Jim,

Please do not reply to automated forum emails/reply. Post you reply on the forum directly so everyone can see the progress and hopefully benefit from any documented resolution here on the forum.

Thank you.

Don't know the answer to your question.

I played around with it more and it looks like the RA is slewing and the DEC is guiding when it moves.

BYE Speed control 100%

RA moves at slew speed
DEC moves at guide speed per the readout

BYE Speed control at 10%

RA moves at slew speed
DEC moves at guide speed per the readout

Thanks for posting here.

Looking at the log time, BYE does issue a MoveAxis command and Genimi does receive a MoveAxis command and does seem to execute it... at least I think it does because to error are reported.

What do you mean by this? The same bullet points in both cases but 100% versus 10% as headers?

Sorry - It does look like DEC is slewing when the DEC button is pushed but its only slewing at Guide Speed - real slow... Adjusting the BYE ASCOM Telescope Speed doesn't change the slew rates for DEC or RA. The BYE ASCOM Speed control does nothing...

I will just use the Telescope.NET app.

Each ASCOM Telescope driver provides a list of valid ranges of rates that can be used by client applications that use MoveAxis calls. Each axis has a separate set of valid rates. For example, the ASCOM Telescope Simulator supports any rate in the range of 0-3.33 degrees per second and 5-10 degrees per second for both the primary (RA) and secondary (Dec) axes. My Celestron mount supports any rate from 0-5 degrees per second for both axes. Some mounts only support discrete rate values like 16X sidereal, 64X sidereal, 1.0 degrees per second and 5.0 degrees per second for each axis.

I do not know what the valid axis rates for your Gemini driver. I also do know how BYE translates its percentages into valid rates in all cases.

If you download my ASCOM Device Hub application and install it from the ASCOM GitHub site (https://github.com/ASCOMInitiative/ASCOMDeviceHub/releases) and then connect it to your telescope, the valid axis rates are displayed on the Telescope Capabilities tab.

I will pass on installing the above driver. Gemini Telescope.NET functions correctly along with other telescope / imaging apps that interface to Telescope.NET.

There's clearly something wrong with BYE. The BYE Gemini-2 DEC and RA buttons are stuck on the existing speeds above; RA - Fast Slew and DEC - Guide. They should be the Same Speed at a given BYE Speed Setting.

admin · November 4, 2019

The speed setting in BYE is based on the Axis rate astroman speaks of, so this might be a good exercise to try his tool, but I respect your decision not to install it. If my memory serves me right BYE will set it at 10% of that range so if the range varies based on other mount settings, the speed at which BYE instruct to mount to move may depend on it as well.

If there's a weak module in BYE it would have to be the Telescope ASCOM module sadly .

JTWaters · November 4, 2019

"If there's a weak module in BYE it would have to be the Telescope ASCOM module sadly" With 3 other astro / imaging apps working correctly? Update - 4 apps.

astroman133 · November 4, 2019

I made the suggestion to use the ASCOM Device Hub to see the allowed axis rates because while some applications may use the driver's AxisRates values for MoveAxis calls, few apps display them. Since Device Hub does display them, this may provide information that can help Guylain make improvements to how the ASCOM telescope control in BYE/BYN works. Unfortunately each mount can have its own sets of valid rates. Only someone with a Gemini II controller can provide this information to Guylain. That said, I understand that you do have a solution that works for you and so do not want to install something else. Best of luck!

JTWaters · November 4, 2019

Understood - I will install the driver later today and post the info.

JTWaters · November 4, 2019

Here's a dump from the above driver. No issues with +-RA or +-DEC. ASCOM Device Hub works as expected with the Gemini-2.

What else is needed?

Connect to the Gemini telescope driver and select the Telescope Capabilities tab. Paste a screenshot into a reply on this thread. It should appear similar to the one below and shows the valid axis rate ranges.

Thanks for helping!

Using Telescope.NET Rel 1.0.72.0

astroman133 · November 4, 2019

Ok, Thanks!

So you can see that the Gemini.Net driver supports 3 discrete rates, since the minimum and maximum values for each range are the same value. Those rates correspond to 796X sidereal, 20X sidereal, 0.5X sidereal.

Guylain should be able to see how he maps the percentages to those values to explain why you are seeing the movement that you do.

JTWaters · November 4, 2019

Let me know if there's going to be a RC fix to test.

admin · November 5, 2019

Well... I think I may have found the issue. BYE/BYN used 10% for the selected rate.

For the primary axis (RA) it uses the first range (796x sidereal = 79x slew speed) and for the secondary axis (DEC) it uses the second range (20x sidereal = 2x slew speed).

So just by looking at code it seems RA is 79x and DEC is 2x; that is a huge difference and seems to be inline with your reported issue. The offending line of code is the second enumerator.MoveNext() in the code below. I'll comment that second line and then I'll try to upload a new RC later this week for a quick test.

                switch (axe)
                {
                    case TelescopeAxes.axisPrimary:
                        enumerator.MoveNext();
                        break;
                    case TelescopeAxes.axisSecondary:
                        enumerator.MoveNext();
                        enumerator.MoveNext();
                        break;
                    default:
                        return false;
                }

Regards,

Good news... When you are ready for me to test it out send me a private e-mail.

admin · November 7, 2019

Hi Jim,

I just finished uploading RC12 in the pre-release section.

I made 2 changes

DEC now uses the first slew range, same as RA
I added a slew scale property. Default is 100. Reduce to slow down slew speed or increase to speed up slews. This may of may not give you additional control.

EDIT: That new property is in Advance Settings.

JTWaters · November 7, 2019

Just downloaded RC12 and did some quick testing.

Selected Gemini Telescope.net.

BYE ASCOM 'Speed' comes up at 10%.

+- DEC buttons work now. +-RA buttons still work.

ASCOM 'Speed' setting 1% or 100% does nothing. DEC or RA speeds do not change. I am assuming that the Speed setting changes the DEC / RA movement speeds.

JTWaters · November 7, 2019

Why not use the 3 Gemini-2 speeds? Slew, Center, Guide OR ... S, C, or G.

Awesome, DEC is now working.

Let me check the scale property; I may have forgotten something.

admin · November 7, 2019

Ok, I looked at it and I'll have to sit on this one until I have more time to look at it; I may remote the scale property.

In any case, the DEC now slews as expected which was the real issue to address.

Regards,

JTWaters · November 7, 2019

Sorry, the '4' Gemini-2 speeds are SLEW, MOVE, CENTER and GUIDE. In order...

More info - If I set the Gemini-2 Hand Controller to CENTER, MOVE or GUIDE BYE RC12 still uses SLEW speed and resets the Gemini-2 Hand Controller to SLEW.

"Ok, I looked at it and I'll have to sit on this one until I have more time to look at it; " I am OK with this but don't forget about it.

BYE does not issue any sort of reset on slew speed, it issues a MoveAxis command only. It is possible that the behavior of the Gemini-2 does set it to SLEW once is receives a MoveAxis command to perform the slew, I don't know.

The comment about sitting on it is about the optional Slew Scale property I added and is not working...I may remove it as this was for convenience only and I thought it may be of value.

Thank you

JTWaters · November 7, 2019

I will look into this and get back to you in a few days.

"It is possible that the behavior of the Gemini-2 does set it to SLEW once is receives a MoveAxis command to perform the slew,"

EDIT - I need to contact the Gemini-2 Telescope.NET developers to determine how MoveAxis works. Give me 7 to 10 days. The Telescope.NET app below enables the user to set the GUIDE, CENTER and SLEW speeds.

According to the previous screenshot from the ASCOM Device Hub the Gemini.NET driver only supports 3 discrete rates for use with MoveAxis. Those rates are 796X sidereal, 20X sidereal, 0.5X sidereal. That is it. This is why the percentage value in BYE does not change the speed. It then makes sense that these 3 discrete rates map to the Guide (0.5X sidereal), Center (20X sidereal), and Slew (796X sidereal) radio buttons in the Gemini virtual hand controller as shown in JT's screenshot above.

BYE's approach of using a percentage value to alter the MoveAxis speed is fine for a mount that has a broad range of Axis Rates like a Celestron mount where any value between 0 and 5 degrees/sec is valid, but will not work in other cases. Such as when a mount supports only a small number of discrete rates, like the Gemini driver/controller or even when it supports multiple smaller split ranges like the ASCOM Telescope Simulator (see my previous screenshot).

When I wrote the Device Hub, I tried to take all types of situations into account. For drivers like the Celestron driver with an Axis Rate range of 0-5 degrees/per second, I arbitrarily chose values of 16X, 64X, and 2 deg/sec. For drivers like the Simulator with ranges of 0-3.33 and 5-10 deg/sec I use the midpoint of each range, so the MoveAxis rates used by DH will be 1.67 deg/sec and 7.5 deg/sec. For the Gemini the user could select any of the 3 discrete rates for MoveAxis. The user selects one of the rates from a dropdown list.

I hope this explanation is of help.

Agreed, MoveAxis is not a universal approach. MoveAxis may have seemed like a good approached when I first implemented it years ago but in retrospect it's not a one size fits all.

This is the main reason why I thought about implementing the Slew Scale in the latest RC to give more control based on the range/speed variant from mount to mount. It's not quite working yet but more reason to make it work
