9.2.22

9.02.2022 Lunar imaging.

 *

 

 Late afternoon and the moon was high in the south east. Fast moving, soft edged, orange clouds coming from the west. Thermal agitation of the image. Sky still turquoise.

160mm Baader D-ERF, 150/10 iStar H-a objective, 2x GPC on ASI174MM camera nose. Superficially sharp but the images don't cope well with 100%.

 
16.24 D-ERF still in place.

16.29 D-ERF still in place.

 

 

 

 

 

 

16.45 removed the D-ERF to check for any difference. More and bigger clouds.

18.05 Back out when most of the cloud cleared. Now fully dark. Ghost clouds crossing the moon. High frequency thermal shaking, brightness fluttering and image de-focusing. There is no real sharpness to the image despite repeated refocusing. Weird, considering how high the moon is in the sky.

Typical! I came back in at 19.00 after it had completely clouded over. I looked up and the sky was clear!
