Hi!

Most interesting! I have a CGE-pro, also with home sensors. I am, however, not very familiar with the different Celestron mounts. Would your changes to the driver be helpful also for this mount, the CGE-pro? I'd be happy to test but I am no developer.

Hi!

Is there a way to restrict the range of movement for the focuser, not just in terms of maximum position but also minumum? If not, could that be added? To be specific: My focuser has a focus point somewhere between 1000 and 1100 ticks. I would like to say to the focuser that it can not move outside of that range. 

What happens at times is that when for instance a cloud passes by, the focuser ends upp in a very different position, like 145 ticks. I don't know why (after failure, it is supposed to go back to starting position). What I do know, is that if it goes too far off, it might catch onto a part of the doughnut produced by my SCT, and then progressively go out of focus. When it has gone that far off, there is no chance that it will find the focus point again, and the rest of the night is lost. 

I use Linear algorithm and that is highly stable - until the above happens....

Anyone recognizes my scenario, and/or have suggestions on how to strictly set the limits for focuser movement?

Hi!

Jasem, how can we check that? The logs still gives very little information.

Hi!
Good idea! In that way, if I get it right, the indi driver is not at all used, right?
I tried last night - so far not freezing - however, being a very intermittent problem, much more testing is needed!

Hi!

So I have checked the checkbox for camera NOT supporting streaming - but I still get the errors - I've had twice tonight. And just as before, I can "restart" the camera by taking an exposure from the Indi control panel for the guidecam. 

And I still get no more info from the logs, except error, that is. 

Any other ideas at all?

Hi!

Haywire: last night, the scope seemed to point to Cygnus, all looking fairly OK (I had not yet aligned in Ekos), I could not focus because the mount seemingly did not track - hence no stars but trails. I slewed a short distance, to see if that made a difference. THis caused the mount to perform what it called a meridian flip - meaning that in crazy speed driving the scope all the way into the mount, pointing down into the ground. I turned the mount off, manually put all in place (nothing broken, thank God), turned on, performed all the steps with the HC, and after that, connected to Indi, and then it worked flawlessly until midnight, when I turned all off.

Hi again!

How do you upload a cvs-file of stars to Kstars? I just can't find that.

Hi!

I trying to make sense of how I can have my CGPpro time and site updated by Ekos. However, if I connect Ekos before searching for home (HC says: searching for home sensors, then asking about time - which is correct, Daylight saving - which is correct, and time zone - which is correct) and then last align - if I do this, mount goes haywire after first or second slew.... 
If I do the whole align process (search home sensors, check time, check daylight saving, check time zone, then last align) BEFORE connecting Ekos, all is fine. Except, of course, time, which is slightly off. Doesn't matter much but a little bit. 

Do you do something differently? Oh and this time I did with recently updated HC.

Hi!

Why would you want to do it inside the sequence? I have more and more favoured setting a new scheduler job for changes, so that the scope also re-aligns. This to minimize the risk of failures affecting the whole night. For instance, if something happens that makes the scope drift (clouds...), I don't want that effect to last for too long. So I prefer spending some time on re-aligning to safeguard and in the end, get more out of the nights. So I would set up each filter as a separate Scheduler sequence (or even split them into 30 subs per job). That said, the filter offset is really helpful.

Ah, OK, thanks! I'll try that. Do you know what it does specifically? And has it affected your guidecam in a similar way as mine?

Hi!

Not sure what you mean. There is a streaming-tab in the Indi-controls, now I have turned streaming off there. Was that it?

Hi!

I've upgraded to an ASI174mm mini as guidecam, guiding primarily through PHD2. And I have some very intermittent issues with it: it simply freezes and does not produce an image. PHD2 tries to reconnect, but fails. The only output I get from the log file is this: 

ASI174MM Mini :  "[ERROR] Failed to get data after exposure (1936x1216 #1 channels) (ASI_ERROR_TIMEOUT). "

I have switched USB cables, now running an USB 3-cable directly from the guidecam to the USB3-port on the Raspberry Pi. Interesting, if I go to Indi control panel and manually click on Exposure there, it capturs one frame and then, it works again!! But Ekos can seemingly not "restart" or reconnect. 

Anyone recognizes this?

Hi!

Maybe this is going slightly off topic but....

When using my (borrowed) CGE-Pro, I can not sync. I do as you with your CGX, choose "last alignment" to make it easy, but after that, Indi control panel just tells me that sync, or update of time for that matter, is not needed since the mount is alrealy aligned. Maybe this is caused by my Nexstar hand control being not updated recently or it might have to do with the mount (??). Is there anything you do in particular with the CGX to make sync possible? And do you use the Nexstar driver? What version of Nexstar HC?

Hi!

Since I asked, there has been the development of a way to search for objects on the internet, both in Kstars and in the Scheduler. So now I just type in the name (or copy-paste) and if it is in GSVC, it will be found. Not so far ASASSN-variables, CSS and the like - still needs typing in coordinates (as far as I know). 

But: it would be good to hear how you import that CSV-file. I produce csv-files as export from VXS, would be handy to just import them, for variables less easy to find the other way.
