Meridian Flip issue Mac EKOS - Me too!

Glad you like the site! A few things to check. This is solved for me now. I'm running 3.3.3 Kstars/Ekos. Once installed, make sure your geography setting is correct. In KStars, it's the globe icon towards the left. Previous versions this location was not saving, which meant the clock was not in the right time zone. Then press the update time button right next to the globe icon to update the clock to the current computer time.

After those things, make sure that you set the meridian flip to >.5 past meridian, and not right at the meridian line. Some mounts will not flip if they can operate past the line. Also, make sure that the meridian flip option shows the Time to flip. This is in the newer version of the software. It will show you a count down timer to the flip (after you select the meridian flip checkbox), and it should reflect the exact time the object is passing the meridian. I sometimes don't see the count down timer when I first press it, and have to check and uncheck it until the timer shows up.

With those things set, the flip should happen. I know that EQMod has a meridian flip button in its settings. you might also want to be sure this is activated. Hope it works! You can test it inside your home. Just send your mount to any object that is near the meridian at the time you test it, and set it to take some images until it crosses the line and should execute a flip. (it doesn't matter if your scope cover is on, since you're just testing indoors.

Where can this option be found because I searched for it and couldn't find it in KStars 3.3.3... Thanks!

It appears directly below (or to the side) of the check box to turn the flip on. (This is not the same as the scheduled park command). I sometimes have to check and uncheck it several times for it to appear. It was in the 3.3.3 betas, I haven’t looked again at the final 3.3.3.

Wonderful, thank you so much! This looks very promising, I'll update and try it out tonight. Much appreciated! It didn't occur to me that I might not be using the most recent version. =P

There was indeed a bug in the calculation of the meridian flip - see this thread . The problem occurs when you are pointing to an object with a small RA value. This is why this bug has not been discovered for a while, since these objects now start to appear during the night.

As said in the thread, the fix is already present in the upcoming v3.3.4.

Thank you Wolfgang, I hadn't seen that thread. Forgive me if this is readily visible somewhere, when do you think v3.3.4 will be available officially? I'm not savvy enough to "build" the files as they are now, I have no idea where I would even start, lol.

And Andrew thanks again for the suggestions! I'm glad yours is working, sadly after updating and testing with a near-meridian object several times (even with delay set to >0.5) it starts off telling me what time it'll flip which is great and looks accurate, but then still just perpetually says "Flip planned.." when that time comes, and then nada. It does seem to accurately predict the exact time to flip will be, it just doesn't do it. So for now until v3.3.4 is released, I can use that time prediction to set Auto Park to be on the safe side, then if I don't fall asleep I can get back on and plate solve it to one of the previous captures and keep going until morning.

I think it's a matter of days until the next release is published. Btw.: if the mount remains on "meridian flip planned", you stepped into the bug. Then it only helps to deactivate the meridian flip for this target.

In other cases, it seems to me that your mount either cannot execute a meridian flip (maybe deactivated somewhere) or the mount time or location is different to that set in KStars.

You mean in this screen?



Because no matter how often I enable and disable the checkbox, I don't see that appear. Unless of course the Telescope Simulator doesn't support it but then why would the checkbox be there in the first place?

Yep, that’s where it appears, right below the checkbox in that open space. I’ve not had any time to hook up my equipment again to see if it’s there in the final 3.3.3.

The mount has to be tracking, otherwise the meridian flip is disabled. Slew to a position east of meridian, then activating should show the remaining time until meridian flip.

Btw.: there was a bug in the meridian flip calculation for targets with low RA values. It is fixed with version 3.3.4.

Here's a screen cap of what it looks like.

Thanks Andrew. I have seen this now as well. The meridian flip time indication only appears if currently an object is being imaged and if the "Flip if HA >" box is ticked.
