Seeing this week has been quite a roller coaster! Monday and tuesday night the seeing was amazing, and I took some of the finest lunar shots of my life. But as the week progressed, the fronts moved in and the wind increased all the time. Thats bad for seeing and today - Friday - the seeing was a paltry 1.5/5, quite bad actually. I used a method to extract the best from the minute of recorded data. By useing only best 25 of the 1200 frames in each set, I was able to capture much clearer images. We can hope for better seeing soon!
Halpha:
Lets start with the full disk using the .5x Antares focal reducer:
Next, the proms full disk with the same setup, a longer exposure and the gamma set for 150 instead of 40. Whoh - look
at that beauty on the upper right!:
Now to implement the 3x Klee barlow. This "shortie" barlow works optically very well in Hydrogen alpha:
Todays "star" of the show, the active region and nice medium sized sunspot, and gorgeous filament:
Seen here now the same field, but the pressure tuner on the scope detuned to a side band - the Red Wing - of Halpha. This shows more of a white light view, but the tiny white dots around the periphery of the sunspot are Ellerman Bombs, tiny micro flares ONLY visible off band.
Here is another small sunspot group now leaving us on the west limb:
The Prom at this magnification is a bit hazy, but you can see the horizontal spikes and tendrils here:
