31.08.2021 Imaging AR2860

 *

Tuesday 31st 60F, bright sunshine, clear sky.

10.17 [CET] First image. Seeing conditions look different from yesterday. Much more thermally mobile. With a "greasy filter" effect.  I may need to retune the PST etalon.

 

 

 

 

10.26 Over-sharpened for detail but with blocky artefacts.

10.37 Using 1.6x GPC for larger ROI.

Exceeds PST etalon sweet spot. With brighter areas on the left.

 

 

10.47 Back to 2x GPC.

 10.53

 

 

 

 

 11.49 Tried the 2.6x GPC but the seeing is shaking too much. 

Back to the 2x but reduced the frame size form 912x912 to 800x800.

 

 

 

 

 

 

 

12.02 Tried with and without PhotoFiltre7. [ImPPG only.]

 

 

 

 

 

 

 

 

 

12.15 Cloud has arrived from the NE! 

12.21 Sudden steadiness.

 

 

 

 

 

 

 

 12.41 Getting shaky again.

 

 

 

 

 

 

 

 

 

13.00 The seeing has gone bad. Pause for lunch.
