Ok, let me know, I'm curious! It also happens that if I use the automatic dark flat generator after the flat shooting the dark flat shooting fails after the 5th retry, so I have to delete the dark flat sequence and manually add a dark sequence with leght determined by flat: does this happen only to me?

Valerio created a new topic ' Making flat: debayered or not?' in the forum. 4 months ago

I have a 294MC and so far I had the automatic debayering disabled and I could make flats with automated flat function in Ekos setting 31000 ADU and 4 second automatic duration with a dimmable led panel.

Yesterday I enabled the automatic debayering for seeing color images in preview but when I started making flats, with always 31000 ADU as target, the exposure time ramped up to over 15 seconds and whas yet to 15000 and I stopped it.

Now my question: what is the correct way of taking flats? I suppose to have debayer disabled and have 4 sec flats

When I use the Polar Alignment in the Alignment module, after Ekos takes the 3 pictures and shows the error triangle on the picture and values in "Measured err" fields, even if I check the "Update PA Error" and click on "Refresh" the triangle stays the same and the error is not updated, even if I make adjustment to Alt and Az. Is there any way to get this working?

I don't know what can be the advantage for ST4 or pulse guiding but for me there are real problems on slewing. Anyway there are people that suggests that ST4 is better but so the contrary...

You're right Jim, that's it! If the mount is tracking, there's actually no real problem or consequences, except that you're forced to use the ST4 cable instead of pulse guiding, but if the jump happens during the slewing that's a real problem becase the mount movement goes out of control! It happened a lot of times during plate solving, and that's a problem because instead of micromovements done for correcting very small arcsec the mount starts slewing on larger distances, or also if it happens during near the meridian flip it can trigger it. What can be done?

Things you don't expect to happen: I had a good opportunity to upgrade the mount and got a wonderful HEQ5 with Rowan kit that came with a brand new EQMod cable and guess what? Still jumping!!! As I just tried to take some pictures, I didn't turn on the debugging log and decided to have a full reinstallation that I'm running right now, etching the SD for a lot of unexpected problems that still happen, such as the ASI 120 mini switching to 8 bit for no apparent reason.
As said, I'll try with a brand new install, anyway any suggestion on how to tackle the issue that is still here?

Little update: I received the new EQMod cable. At first it seemed it solved the problem, as in the cold run there were no errors in the log, but I'm trying it right now on actual shoooting and I still see jumps... so cable is innocent!

Ok, so at least what is wrong on Ekos is wrong on Ascom too. I'll wait for the new cable on monday and will try again!

I followed your instructions but logging does not start and I don't know why. When I click to "ASCOM Connect" it creates a file in the log folder named i.e. "ASCOM.Serial.1803.204490.txt" but the content is only as follows:

Nothing else is written or added.

I tried to save the comms trace log in the EQMod window that I disable first in your instructions, at least there's some info in it, that I attach. Am I missing something or doing something wrong?

the person I contacted knows Windows system, so it would be good to see if there's any way to get these log under ASCOM, do you know if there's any way to have the same activities logged under Win so to get the error?

The mount works fine both with handbox and with Windows software, as said I usually polar align with NINA/ASCOM on Win10 as it's much faster and reliable than the Ekos one, but I never guide or take pictures because using the laptop near the mount would be very uncomfortable for temperature and cable lenght, that's why I turned to Astroberry. It's about two weeks that now I get very weird behaviour in NINA too: the mount (on ASCOM) randomly disconnects, I get messages that the mount didn't move the expected 10° but only 6° or the mount always moves eastward even if in the plugin I set to move westward.

Just to clarify, I get the reading only on a way, if I invert the polarity reading on the meter I always get a 0. I don't know if it's normal, but just to be sure.

It's a transformer made by the famous technician / repairer that made the EQMod cable.

Well, I don't know if this can matter, but at this moment most probably I think it does: I bought this mount used and I firstly used if with a 3A transformer that had no ground connection; on the very first use probably by a very unlucky event, the mount phisically burned the controller and also part of the handbox. The person I bought the mount from works for a very very famous european webshop and gave me the contacts for the technician that works with them but also on his own and he's very famous, at least in the italian astronomical community. He changed the controlled, as it was burned beyond repair, but verified that the other electronics, including motors, worked fine; he made the 7A transfomer robust enough to withstand any electrical problem and the EQMod cable. Since then the mount works absolutely fine, except for these errors I found thank to you, but I don't know if there were before the accident and if this event relates to the errors
