PHD2 can't be used as guider in KStars 3.4.3 #57734
Using PHD2 with KStars 3.4.3 works fine for me. I see in the error message it's trying to connect on port 0. That is incorrect. It should be port 4400. In your profile editor, make sure the port number is set correctly.

Hi, This happened to me about 3 nights ago. However, since loading the most recent nightly build, (I was using the previous nightly) it is back to normal. I had attributed it to a slightly different start up than I usually do and ended up using the internal guider )after several attempts to connect my mount) which I have to say was very good and made me wonder why I was using PhD2. Thanks to all who contributed to the improvements in the internal guider!!
Tonight I am back to PhD2 and it is all working as expected. Try loading the latest nightly build and hopefully you will have the same result.

If you are using a Pi with Ubuntu just put this in the terminal window and it will download and update your version to the latest nightly build.
sudo apt-add-repository ppa:mutlaqja/indinightly
sudo apt-get update
sudo apt-get install indi-full kstars-bleeding gsc
If you want to return to a stable version the instructions are here including the instrctions for other versions of linux

Yep I like the drift align feature too. But usually I am time poor when imaging from my backyard so I polar align with SharpCap and a DIY "polemaster" . This takes literally less than 5 minutes and gives me 0.6 arc sec/px guiding which for my mount is as good as I ever get.
I will use drift aligning if I am imaging for a few days as it is worth the time invested and is pretty satisfying to get it spot on.
I was just amazed how much better the internal guider was, mind you the last time I attempted to use it was over 2 yrs ago. As you say EKOS refinements have really made KStars really easy to use.
It does need a feature that controls the weather though!

Agree with Paul (phomer60) on drift align and dark library. There are just some instances where a drift align is highly desired. I would like to use the internal guider, but absence of drift align is an issue for me. I guess I could start with PHD2, drift align, then disconnect and switch profile to use the internal guider, but that's a pain I could avoid if Ekos included a drift align feature. I will try this dual/split config during next dark time.
@jcj: re: "The reason I wanted still to use PHD2 is because the GPG RA Guider asks for the Major Period . How do I get it ?"
Open the PHD2 Log Viewer, select a guide interval, right click in the graph and select "analyze selected raw RA". In next pop-up window, select frequency analysis button (top left). The period will be obvious. Use the mouse to mouse-over at the exact location of the major period, and see the value in the bottom left of the GUI.

As Kevin has indicated, GPG RA Guiding and PHD2's Predictive PEC are the same thing pretty much. Like PHD2, you don't have to enter a period for Ekos, you can check "Estimate Period" in the settings and it will do its best to estimate it. The difference might be the initial estimates, but if you set it 200, then you'll have PHD2's default starting point. After you run for quite a while and it seems settled (e.g. after 15-20 minutes), re-open that Options page and take a look at the estimated period, At that point it's probably pretty close to your actual period, and you can just uncheck estimate period from them on.
The reason I wrote that it's best to predetermine your period is just that it will probably make your first 15 minutes of guiding quite a bit better, probably no big deal the first time you do it, but you wouldn't want to repeat that every time you start guiding.
Sorry about the scrolling thing you mentioned. You don't really want to mess with any of the "advanced options" on the bottom of that page anyway. In fact, I believe if you resize that Options pop-up page, the system will remember its size, and there will be no need to scroll down anymore.
