I've made those changes too, but unfortunately no, the issue still remains :-( I can't get it solved even on a simulator profile. I have just the same errors.

And to be honest I can't understand how those infos are written into the header - so I could change them. Maybe it is something fundamental on my profile that I do not know, cause till the previous version, everything was working properly.

And my setup is pretty simple : SkyGuider Pro, DSLR, ZWO.
My profile:
Mount = iOptron SkyGuiderPro (tried with Telescope Simulator too)
CCD: Canon DSLR
Guider: ZWO CCD


PS. Yes, it was my first and only session that night.

So really you don’t need to change the information about the telescope position in the header of the image that was taken, that is automatically taken from KStars and the drivers knowledge of the telescope location. When you first start up, your mount should probably be in the position looking at Polaris and then once started up, you should slew to your first alignment star and take a plate solve. Then do a couple more in different spots before you go to your target.

The.one exception to this is that some mounts/drivers have a warm start mode where if you have the scope still in the same spot as a previous run, you can just start right back up

The other part about what you said about getting a simulator plate solve to work, are you using the internal solver or ASTAP? And whichever one it is, do you have the right index files or catalogs?

My steps are quite usual, just PA and then "slew" (manually of course) to my target.

I've tried all the available solver combinations but none of them work. I have all the required index files (and even more).

Right now I can see that even the individual ASTAP installation can't solve the image (on my RPI4 and my Mac)

Try unchecking use scale and or use position and make sure that the alignment logging is turned on in ekos. Also when you say the index files are installed, please go into the ekos index file downloader and make sure it can find them .

When you say you “manually “ slew I hope you mean using the hand paddle and not just pushing the scope (unless there are absolute encoders)

Also this manual slewing happens after you turned on ekos and not before?

If I can recall correctly I switch on the RPI after I slew (yes not pushing) to the target, I am already polar aligned so I proceed with the PHD2 and then start my Ekos sequence.

Tried with unchecked both, no luck :-(


Please ignore the "Current CCD FOV", it is just the simulator. I've already tried also with the actual real FOV, with no luck.

Ok, looks like your index files are probably good, this is on the same machine you are trying to solve? That won't help ASTAP of course, but I assume astap already has its files.

In the second screenshot, you show that the "use position" and "use scale" are unchecked, which is good if solves are not happening certainly, though you won't want them unchecked later on once we figure out what is going wrong.

But then I note that there is a lot going on in the log you pasted below and I'm not sure I'm following it clearly. It looks to me like you tried the different solvers in quick succession is that correct? But in looking at it, it looks like the scale and position were still being sent?? I thought you had disabled the "use scale" and "use position" settings? Were they or were they not disabled? if you had disabled the settings before trying to solve, we should see the internal solver or local astrometry starting a bunch of parallel solvers, but that is not what I see here. I also noticed in the ASTAP command that the RA and DEC were sent. So based on these two pieces of evidence, I don't think "use position" was turned off when these solves were attempted. Maybe you turned off this setting later?

But then I noticed something else odd, it said you were loading this M45 image with the incorrect headers in it, in the middle of solving? Are you trying to do load and slew or are you trying to solve a simulator image? Sorry I am a bit confused.

Another note, if you are trying the Simulators and solving, please slew away from the pole before trying to solve. Solving tends to work better away from the pole with the simulators.

Ok let me one moment to step back and ask, so we could avoid further confusion : I have those M45 subs with the wrong fits header.
I know that I can solve them successfully on the Astrometry website, already done that.
I am right now into my RPI, with Ekos, indoors due to rain. Is it possible just to load them to Ekos and plate solve them? If yes, how?

Sorry, I tried to respond to this last night, but for some weird reason I couldn't get on the website.

I was about to say yes no problem, just use "load and slew", turn off "use position" and be sure to not use ASTAP because it doesn't do as well as the others with blind solving. BUT, then I just tried it and I think I found a bug in KStars. It just went ahead and used the information in the FITS header again even though I unchecked use position. I had thought we had set up "load and slew" to work the same way as the "Capture and Solve" feature. Unchecking the "use position" button worked perfectly in "capture and solve" I just tested that too to make sure, but apparently it ignored it when using "load and slew". I am sorry if I led you astray on that one, that is a bug I think. I will ask if somebody changed that behavior for some reason or if I did it wrong in the first place. I think there should be a way to tell it to ignore the FITS Header information, even if it is not the same setting. I will ask. We should be able to resolve this quickly.

But anyways, that doesn't really affect the issues you were reporting before. The main issue you had in the field was that your telescope, the driver, and KStars thought your telescope was pointing at Polaris when you were actually pointing at M45. So when you tried to solve with the "use position" option checked, it caused all solvers to fail. I think the reason for this is probably that you set up your telescope, sent it to M45 and then you turned on KStars/INDI with the options selected that sent the computer information to the telescope which told the telescope it was pointing at Polaris again. My recommendation is to turn on KStars/INDI while setting up your gear and THEN to slew to M45 so that they both know they are pointing at that..

I think you had also reported some issues with the simulators solving. So, while it is raining, what I would recommend, is that you try playing around with the solver and the settings using the simulator inside the house with different options and scales inside the house until you perfect everything. Then when you go back outside you will be ready for it. Please let me know if you have any issues with that and we can resolve it all before you go out.
