Elongated stars after new profile/calibration/baseline

[Phil Bordelon]

Thank you for your time and assistance to so many.  I have learned so much from just following this forum.

FYI, logs from the night of the problem and the night before are linked below along with pertinent images and screenshots.

Now my issue:  Due to weather, I've not imaged in over two weeks.  I setup up my rig for imaging on 5/13-14.  I calibrated with PHD2 at DEC 0 using an existing profile.  Everything went fairly well guiding wise.  I generated good stars in all my images that night (see below Dumbbell Nebula screen shot) and then took the rig down as I often do.

I readied the rig again the next night (5/14-15).  This time I decided to do a guiding baseline following the document "How to create a baseline for guiding results using OpenPHD2"

1. I created a new profile named EvoGuide50ED_662_20260514
2. Slewed to DEC 0.
3. Calibration result was "acceptable" Screenshot of results is attached. (I saw "Meridian Flip" but just watched the mount for trouble.  Didn't see any.  Should I have restarted the process?)
4. Ran Guiding Assistant for over 15 minutes and clicked Stop.
5. Applied all the recommendations except DEC backlash compensation.
6. I moved to the Leo Triplets for imaging and I let it guide for over 20 minutes while imaging that target.
7. Resulting images from two 4 minute subs (taken 2026-05-15_00-01-26 and 2026-05-15_00-05-27 respectively) are attached as "ElongatedStars*".
8. Compare to this a 4 minute sub from just the night (with a pre-existing profile/calibration) before the baseline was done. Attached as "GoodStars_20260514.png"  Stars are fine.

Please disregard my previous emails detailing my guiding problem.  Tonight I did a created a new profile using the wizard, ran a calibration, a GA, and guided after that for 15 minutes.  The result so far has been the best guiding on this mount (Skywatcher Wave 150i)  since I started astrophotography a year ago.

After an hour of guiding, PHD2 is reporting 0.45" - 0.56" Total RMS.  Of course, as I write this, RMS has crept up to 0.65" over the last 2 minutes!!

Still very acceptable.  And no trailing stars.

Thank you.
