Sunday 4th 64F, bright but rather a lot of slow moving cloud. 

10.00 Set up for H-a imaging. Fairly steady seeing so I have changed to the 2.6x GPC for more scale. 

10.15 Still waiting for the cloud to clear. Have reversed the PST etalon. A cool breeze.

10.23 First image today. Over-sharpened due to thin, high cloud streaming across the image.

 

 

10.48 Transparency and steadiness prompted change to the 2x Barlow. Now lots of thermal shaking and defocusing as well as cloud crossing. What an optimist! 800x800.

10.56 Cloud has cleared for a while. 912x912.

 

 

 

 

 

 

 

 

 11.13 Retuned the etalon and refocused!

 

 

 

 

 

 

11.31 Still capturing away as the seeing comes and goes. Trying different settings in Autostakkert and ImPPG.

 

 

 

 

 

 

 

12.00 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 12.27 2.6x GPC for a wider view:

 

 

I have been experimenting with "full frame" 1216x1216 and up to 3000 frames.

 

 

 

 

 

 

 

Thin high cloud i spoiling the fun.  I have never had the seeing last until mid afternoon.

 

 

 

 

 

 

 

 

A crop of the previous image: 

 

 

 

 

17.30 I was hoping for steadier seeing but thin, high cloud took over.

18.00 Still obscured.

18.06. A lucky clearing.

 

 

18.54 Last image before the trees intervened.
