Mmm, interesting. I now tried the HA>0.1 and the mount still didn't flip, just continued imaging. Same things in the logs using an AZ-EQ6 and EQMod driver.

So I'm trying a couple of other things and found that manually selecting a fairly small star works much better. Can I make Ekos not select the big stars? When I centered on Dubne it actually started focusing on it, being way too bright I'm not sure that was the best choice. :)

I'm guessing it's not going to use 100% of the CPU for 2 sec, so that wouldn't affect the rest too much. This method, as far as I read, is also not meant for the Pi perse, if it would work it would be nice, but it's not the goal I believe. And why would you want to guide much faster than 2 seconds? I always guide at 3, lower and I'm just chasing the seeing.

I will try that maybe tonight yes, it must be some setting that differs between the two, SGP has a optimization workflow for getting it right with all kinds of calculations to optimize set-size etc. Maybe that also helps.

Well, in SGP the star-sizes go up in predictable ways on both focus in and out, getting a symmetrical V-curve. In EKOS I get sort of a nice straight steep slope on 1 side, on the other side the slope is much lower as if the focuser isn't getting out on that side with the same amount as in. True, EKOS doesn't do an entire V-curve, but still the points on 1 side should be rather similar as on the other.

Maybe, but the 15 meters (or 49 feet) were chosen at random. :) It happened to be about the distance in between the devices. I know of someone running a 30 meter Lan cable just fine as well, I guess with an active switch or so.

Yes I did notice that, but even then, when it takes the first big steps, the points are pretty off in comparison to SGP. I wonder if it's due to my optical train, but it looks like it's not the best method for it.

I'm not sure if option #2 is that problematic, I have pretty fast success with SGP doing it like that. Granted it takes 10 sec per picture, but I'm not focusing all the time, just once or twice in a night. I do notice a big difference in my routine for EKOS and in SGP, maybe it's because of settings, but in EKOS I can't get a nice V-curve, focusing outward looks ok, inwards it's staying rather flat until it rises. In SGP I get a very nice symmetrical curve... not sure what the difference really is, but I now use SGP for focusing.

So this is actually not a problem for successful guiding, but I'm getting a grey image in the guide-module with no stars to be seen when I use 2x2 binning and the High-Pass filter. Ekos itself does see them though as guiding is fine.

Yes indeed, variable stars are a good way, though not necessarily the most exciting bit of astronomy. Important nonetheless. :)

Well, as amateurs it's rather difficult to really get extra valuable science into todays astronomy. However, as professional astronomers don't have a lot of time behind the super expensive telescopes out there, it's sometimes an amateur who discovers a new supernova or even a type of nebula that wasn't picked up before. These are, however, a bit rare I think and it requires a lot of analysis and knowledge. Would be very cool though to be able to add some, sometimes they ask the public to help with something.

Excellent choice, you won't regret it. I have a 7 meter cable feom my telescope to the outside socket in the garden, than a 15 meter cable under the house to a powered switch from TP-Link. From there another 15 meter cable to my internal network (+internet) which is another powered switch. From that switch the final 15 meter cable goes to my computer inside. Ping times are about 0.7ms with 0% packet loss and I can stream live video from my 6D at around 5 fps. Downloading a raw file takes 2-3 seconds, and the USB over IP now stays connected during the night if I want to use that. All of these things either didn't work or were way slower before. After a year of fiddling with wifi extenders, I gave up on it. I had great sessions on wifi, but it was more the exception than the rule and this is now reversed. ;)
