Wednesday 22nd 60F, blue skies but cloudy from the west. 

I spent some time evening out the coverage of the GRP shutter covers on the ribs. Trying to move them by hand just didn't work. 

So I used long lengths of 2x4! The resistance was provided by pairs of 2x4 clamped together. These were placed with one end against the shutter rib and the other braced against a paving slab. After a few [noisy] bangs, with my battering ram, the overlap on each side was even. I had to slacken off the nuts on all the slotted brackets first. Then wallop the edge of the shutters near the top with a 3m/10' long length of 2x4.

11.28 [CET] Imaging. Not bad detail but the PST etalon sweet spot ring is harsh this morning. I have aligned the BF with the focuser drive rod. It hasn't helped. 

Nor has the sheer quantity of cloud. I am not having enough time to re-tune during the brief bright periods.

12.22 After much tuning and tilting and rotating the BF relative to the etalon. Just for a change I relaxed the Noise and AP settings in AS!3.14. It actually seemed slightly better than the tighter settings.

 

12.22  The same image but further processed in PhotoFiltre7. Auto Levels + Gamma + Contrast + Histogram. These are my standard steps with most Solar images.



 

12.49 Still experimenting. Hovering the cursor over any image should bring up the details hidden in the image name. 

 





 

 

 

 

 

14.33 Back after lunch. More fiddling with the etalon and refocusing.

 

 

 

 

 

 

 

15.28 The wind is blowing the telescopes around.
