Peter Kennett created a new topic ' Strange result during Polar Alignment' in the forum. 3 weeks ago

I have been using the Polar Alignment tool for months without any problem.
But tonight, something strange happened. I am using the same version of KSTARS over the last month, and had no problems until tonight - even though I have not updated KSTARS recently.
I started the Polar Alignment routine, and it came back and told me I was off by a couple of minutes. Nothing unusual there.
But the SCREEN was showing me being WAY off - almost out of range of the tool. I selected a star as usual, and the amount I needed to adjust was appropriate.
I did this three times, getting closer to perfectly aligned each time, but the screen was not zeroing me in. Very odd.

Only works for me on my MAC when I have images also saved on my Mac. If I keep them on the Ubuntu box at the scope, then I will not see them in the Summary Screen.

Peter Kennett replied to the topic 'Off-Centered - While Dithering' in the forum. 1 month ago

I wonder if this is a problem with polar alignment. I have been making sure my PA has been within a few Arc Seconds and noticed my drift virtually went away.
Last night I let my system run for 4 hours, taking images every minute and dithering every 4 frames. Four hours later the target was no more than a minute off.

Yes! This is what I have seen over and over. It seems to work well the first time auto-star is used, but then after that it usually fails after I move two a new field.
This happens of course after a meridian flip, but also happens when I just slew to a new target field.
The guide star box seems locks on to the same area from the previous search, even when that area is now devoid of stars. It should have searched the whole field again, but it doesn't.
The meridian Flip video I made was one success after three previous fails. It's random if the guider will find a new guide star, even when there are tons of stars. That little green box just doesn't seem to look in new areas after the first time.

Peter Kennett replied to the topic 'Re-alignment in Scheduler - is it possible?' in the forum. 1 month ago

I've noticed this for the last two years. It used to be worse, where I needed to re-align after 20 or 30 frames.
Now I still need two after 60-80 frames. The drift is certainly there (with as low as 2 pixel dithering every 4 exposures).
I currently use a wide FOV (348mm F/L) but I know once I jump to a narrow FOV this will be a serious issue.

No Mac vs Windows fight. I use both.
I just don't use Windows on my own time in my house.

I’m in a similar frustration boat, in that every new update breaks something else that worked before.

But I hate using MS Windows and while I put up with it at work, won’t have it in my house. The Mac OSX version works better than the Linux version so once I finish my observatory I will bypass the Linux machine I use as a bridge and direct connect a Mac to my equipment. My new mount (CEM120 EC2) will make that easy with its built in USB ports right at the dovetail plate.

In the Linux version of EKOS, when I click on "Options" from the CDD window, the CONFIGURE window does not open to the front, but instead it stays behind the EKOS window.
This is not a problem with the MacOSX version, but has always been a problem with the Linux version on my Ubuntu OS machine.

This is what is strange, because last night mine was successful again.
Ever since I made sure the "solve and slew" button was set, and that I turned off "Subframe" in the guider, my success rate went way up.

Peter Kennett created a new topic ' Had a good automated Meridian Flip last night' in the forum. 1 month ago

Here's the video: www.youtube.com/watch?v=3n_PK-J49WE

I was lucky in that a guide star was found. That is normally the biggest reason for failure.
I used to have the flip fail a lot until I realized that EKOS does not reset the ALIGNMENT module to use "SLEW to TARGET" option if I had left it on "Sync" only.
To me that is a soft bug, or at least a usability fault. In order fir the automated flip to work it MUST slew to target, but if that option was not selected in the Alignment module, then it fails and only syncs.

This happens to me almost all the time. The only time the SUBFRAME and AUTO STAR options together works, is by pure random luck. I can't see any cause and effect as to why it fails.
And not just with automated flips, but anytime I try to use these features. EKOS just seems to pick a random spot, usually with no stars in it, and tries to guide on it., This is with UBUNTU and its my MacOSX versions.
For the life of me, I have no idea how others are getting it to work. It has not functioned for me for almost two years, and I keep my software to to date.

When I do use the automated meridian flip, I have better luck if I turn off the "Subframe" option. Then I get about a 75% chance of finding a guide star. Otherwise it's about 10% with the subframe on.
