28.09.2021 Imaging.

 *

Tuesday 28th 57F, clear and sunny. Steady seeing but transparency poor.

10.46 Large disturbed area on the western limb. My clumsy attempt to bring out detail has lost the limb in darkness.

 

10.48 New AR on eastern limb.

 

11.03  Dreadful image. Opens from AS!3 as pre-sharpened in ImPPG. Yet no sharpening applied. Struggling with the PST etalon sweet spot again.

 

 

 

 

 

14.07 Back after lunch.  Better than this morning.

 

 

 

 14.15 The AR on the eastern limb.

 

 

 

 

 

 

 

 

 

 I seem to have spent the entire day trying to tune the PST etalon. Rotating the BF relative to the etalon went on for hours with nothing to show for it. Each, small rotation required optimizing rotation and tilt of the etalon. I also tried lots of settings with AS!3 but it made no difference to the sharpening once opened in ImPPG.
