FIxed. I had not upgraded the firmware on the R-Pi and/or enabled the camera module.

Hi!
I'm trying to get a Raspberry Pi camera to work with my Stellarmate. I have installed the camera and when connecting with Ekos all looks fine (I think). However, when I try to take a picture, I get the following error:

[2024-02-20T09:11:06.657 CET INFO ][ org.kde.kstars.indi] - V4L2 CCD : "[ERROR] Failed exposing, the absolute exposure duration control is undefined, and stacking is not ready. "

[2024-02-20T09:11:06.714 CET INFO ][ org.kde.kstars.indi] - V4L2 CCD : "[WARNING] No exposure or streaming in progress "

Any ideas what I am missing?

Full but short log is attached.

Hi!

Yes, there is a lot on Aux on CN :)

The CGE-Pro does not have a USB port. It has 2 Aux ports and one PC port. I do have the specific "programming cable" mentioned in the text you cite (article no 93922). That is the one I also tried to use with Ekos and Celestron AUX driver, where Ekos identifies the mount but can not move it.

What does work for me is connecting to the hand control (either USB-USB or standard RS232-USB depending on which version of hand control I use - I have 2 different).

I hope I am not confusing things?

Hi Joaquin,

Good to hear you share my interest! As for the HBG3, I actually managed to get a PCB so I believe the hard part is solved.

But: as I wrote before: the AUX driver and the PC port does not work for me. Should it...?

Hi!

I have a CGE-Pro mount and am currently using the Celestron HC driver, with a cable to the handset connected to the mount. However, I'd like to get rid of the handset and the need to align the scope before connecting Ekos.

This mount has a PC port and I have a cable that works with Windows and the Nexremote controller. I can also use this cable with Ekos and the AUX driver, and the mount seems to be recognized. However, nothing else. I can not slew the mount, not control it at all. Is this to be expected or am I missing something?

So I was planning on using the AUX port instead. As I understand it, I then need some kind of adapter/converter (not a standard RS232- USB), and found the Homebrew version 3 on Cloudy Nights (www.cloudynights.com/topic/854327-homebr...-wifibtgpsmusbrelay/). Is that what I need?

Grateful for any advice (I do find these Celestron ports and various modes of connecting confusing)

Hi!
I solved my issue by buying a new filter wheel - turned out it was a hardware problem. Can you verify that the filter wheel works correctly using ZWO own software?

Hi!

Not sure this helps but here's my experiences:

I have 2 QHY cameras and have occasionally had similar issues. For one of them, the issue seemed to be solved by having a separate USB cable from the camera - not running it through any USB hub (I have a powered USB 3-hub for focuser, filter wheel, and guide cam). For the other one, swithchg USB cables and hub seemed to solve the issue.

Moreover, at times my QHY 268m simply hangs and does not respond. I disconnect both USB and power, and reconnect, and it works again. This is typically when starting up, and then it will work the whole night.

Hi!

And I can now confirm that the problem seems to be solved, after upgrading the handcontroller to the very latest firmware.

Thanks a lot for the help!!!

Hi!
No I had not seen that... thanks, that is a very precise explanation... :)

Will upgrade as soon as I am home again.

And hi again!

I can now confirm that this happens when I platesolve and sync with anything with a negative DEC, regardless of how close to the meridian. I live at 55 degree latitude so there is not so much sky with neg DEC values here, at least not if we take the neighbours houses into account... but there is some sky.

So: how come this is all messed up when there is negative DEC values? What on earth can I do? I wanted to capture spectra of UX Ori for a pro-am project....

Hi again!

Here's another one. I moved around, closer and closer to UX Ori, and then finally did a plate solve and sync at UX Ori. Then it happens again - scope seems to be at Polaris. THis time the log says "Pierside U"....

Hi!
So tonight it is clear here and I am experimenting. I did as you suggested, Toni, factory resetted the mount, and then started with "last alignment". So I have not done any alighment with the handcontroller. Then connected it to Ekos and ran a number of plate solves and syncs, all worked well, both sides of the meridian.

Then I imaged for 2.5 hours.... (CQ Tau), and then slewed to UX Ori. And NOW things are weird again. Suddenly, without doing a meridian flip (since UX Ori now was on the same side of the meridian as CQ Tau) I did a plate solve and "Slew to target". And suddently the mount in Kstars is placed on Polaris. I think (I am not sure) this is what happes at line 81382 in the attached log.

I will keep experimenting for some time. Could it be that the area around Orion does something particular to the mount? Or the switch to negative DEC values....?Magnus
