Saturday 12th sunshine all day again but gales from the SE have made it impossible to image for days.

This blog has become my ATM design, build and imaging diary. I have recently built several new telescopes, a large equatorial mounting and a raised 10' [3m] dome on an octagonal building. Be aware that I deal with building solar telescopes. Which are potentially VERY dangerous! I can accept NO responsibility for any action not directly supervised by myself. You are NOT entitled to blame any other person for your OWN lack of skill or ignorance. You copy me at your own peril!

Tuesday 8th overnight frost then sunshine.
11.54 [CET] First image. Rotating the Lunt B1200 BF relative to the PST etalon.
The light bridges are absent after processing. Fleetingly see on the monitor. Very soft image.
12.04 A more gentle processing. Heavily cropped to avoid PST etalon brightness in the corners.
15.14 Afternoon session. Slightly steadier seeing.
15.44 A disturbed area without spots. The PST detail is badly offset on the upper right. If only it were evenly spread across the entire image.
15.50 The seeing has gone to mush!
Wireless Internet from indoors was at 33Mbps today. Fastest yet.

Monday 7th 39F Struggling with the PST sweet spot/ring. Keyboard playing up. Changed the batteries. Still misbehaving.
11.37 [CET] first reasonable image. Very localized detail. Particularly top left. [NE] The seeing conditions are becoming highly mobile. With short periods of being completely out of focus.
I carried on until 13.00 but the seeing became worse. I kept rotating the Lunt BF1200 and re-tuning the PST etalon without obvious improvement.
15.09 Back again with 2x GPC instead of the 2.6x.The wider field of view just exaggerates the PST's sweet spot ring.
15.27 Changed to 16 bit in SharpCap. An improvement considering the poor seeing conditions. Frequent defocusing of the image.
15.40 Still trying to fight the poor seeing conditions.
The delicate light bridge across the largest umbra was completely lost in processing. I was pushing much too hard to drag some detail out of the mush.

Thursday 3rd March. 32-38F. Frost and mist cleared to sunshine.
Seeing conditions remain awful. Difficult to focus and processing is a waste of time. I tried varying the number of frames captured and stacked with no difference. All mush! I have checked the optics and they are clear of dew.
