After another long break with very little solar activity, I'm back. Slightly different setup now, I'm using the camera a prime focus without the dispersion prism, but with the nose piece cross threaded to create a tilt effect to remove the Newtons rings. Also just a single frame so the small blocking filter and small sweet spot is visible in the image.
Lunt LS50 THa & Altair GPCAM2 130M.
