I had some decent seeing for a change in the morning so I went for some Calcium images.  I use a Lunt Ca filter module and an additional Lunk Ca filter stacked behind it.  I tried to tilt the second filter in its cell and it seemed to improve the images or it could just be the result of good seeing.  The first image is of AR 2872 and a surge prom at the bottom of the image.  The spicules towards the bottom of the image look sharp while the ones on top seem to be lost in some noise.  Also, I think there may have been a prom near the top of the image but it too seems lost in the noise.  The second image is of AR's 2871 and 2872 the image is compressed to fit the requirements to post.

 

Telescope used CR-6 @F/14.5 (masked to 83 mm) and ASI178
