Thank you, Markku (and also Alan). I didn't really think this was a bug but it remains true that the CCDCiel program somehow knows to invert the image to right side up, or maybe it's just dumb luck. Perhaps it knows something about the telescope being used and makes the adjustment. Is this a feature worth asking for? For now, I can just invert the camera, I suppose. Now I have to worry about focus which was my original purpose in starting this thread.

Alan:

I feel fairly certain that you are wrong about the inverting being due to the telescope optics.

The reason I can say this is that, with nothing changed about the scope, its focus and what it is pointing at, with the camera in and connected to my Rasberry Pi, I can take a preview with the program CCDCiel and the mountain is shown right-side up. Then, I exit CCDCiel and start EKos and do a preview. The mountain is shown upside-down. This tells me that there is either a bug in EKos, or, much more likely, a setting in EKos that I don't know about which is inverting the image. I would like to know what that setting might be. Or possibly, CCDCiel is automatically inverting the image to make it right-side up, and EKos is not.

Thanks agiain, Juergen.

What do you mean by tracking? If the scope is aligned you can make it go to any visible target the software knows about, and it will stay on that target as it moves. Is that what you mean by tracking?

As for focusing on the donuts, these particular donuts were appearing at irregular intervals on the screen, for maybe five or six previews, moving across the screen each time, which made me think they were airplanes. I could never see any donuts that stayed fixed in location on the screen.

Also, do you know why my mountain picture was flipped upside down? And whether the focus quality of that picture would have been sufficient for alignment?

In spite of my earlier semi-success with obtaining focus during daylight, at night it's still the same mess.

Leaving this focus untouched, I have pointed the scope vaguely at the direction of Mars. But all I get is this grainy indistinguishable mess. Tried playing with gain and exposure settings but to no avail. Every once in awhile I do so see some poorly focused "donut" crossing this screen indicating a poorly focused object but it moves quickly across the preview loop before I have a chance to try and focus it better. I can only surmise it represents an airplane. How do I finish focusing the scope at night and for what exposure?

Okay, time to fess up that I really don't understand any of this. I've been getting by without understanding fully what I am doing.
When I point my browser to astroberry.local/desktop, this brings up a web page that identifies itself as "astroberry - noVNC". What's with this "noVNC"? I've newer understood what that meant. It looks and feels like it IS VNC i.e. a "remote console" . If it isn't VNC then what is it?

How would this setup you are recommending work? And how does it differ from my current setup? It sounds as though it would do what I want. Basically, that's keeping all the files generated on my laptop, not my Pi.

Thanks! Progress has been made!



However, why is the mountain upside down? EKos seems to default to this. And no, it's not that the camera is upside down. It isn't. In fact, I found that CCDCiel, with its larger window was a better way to dial in the original approximate daylight focus. CCDCiel makes the image right-side up. I found the "flip vertical" option but this only worked for completed previews. If I tried that option in a preview loop, it would always go back to upside down. Is there a way to make right-side up the default?

Also, CCDCiel allows debayering in the preview. It's not very good, the colors are off, but there's something. I did not find such an option in KStars.

Anyway, I will be eager to try observing in the night sky with this setup. I hope the focus will be good enough. It's still not great.

I have given daytime focusing a shot and still no joy. The scope is pointed at a mountain 2 or 3 miles away. It is clearly focused in the eyepiece. When I replace the eyepuece with the Svbony-305 I can see no detail whatsoever, focused or not. I can play with the Highlights/ Midtones/Shadows settings to darken or lighten the image but it's always a flat, undifferentiated rectangle, no detail visible. Similarly, playing with the Gain, Offset, etc.You can see the settings I used. Not sure what to try next. There are also some INDI camera settings I could play with. Grateful as always for any ideas.

Thanks.

I don't actually need or want to use SSH which is why I asked in the OP if I actually needed to be doing this. But I could not find documentation about how to set things up with the Pi at the telescope and all the software on the laptop (except, of course, the Indi Server and astroberry). Can someone point me there?

So we come to the first hurdle. How does one do this? I am using the previewer but I don't know what are reasonable settings for this.

I point the scope at the sky, the sky is reasonably dark, but I can't capture anything that looks like the sky to focus on. In the attached screenshot you can see my settings and the preview that is not recognizably the sky. What should my settings be to make this initial preview so that I may focus the scope (must be a manual process, on my Celestron Nextstar 4se, no autofccusing available).

Also, I have no idea what the shadows, midtones, and hightights should be set to in the preview window. I don't understand what these controls are for.

Please help this noob!

I think I want to use Indi remotely. I have a Raspberry Pi at my scope running Astroberry. I want to run KStars on my laptop (inside) and communicate with the Raspberry Pi wirelessly.

Reading the manual, section 7.6.2, I find this:

But running this command only brings a syntax error message on my Ubuntu 22.04 laptop

$ ssh -L 8624:192.168.86.61:8623
usage: ssh [-46AaCfGgKkMNnqsTtVvXxYy] [-B bind_interface]

           [-Q query_option] [-R address] [-S ctl_path] [-W host:port]
           [-w local_tun[:remote_tun]] destination [command [argument ...]]

What am I doing wrong, and do I even need to be doing this to achieve my goal?
