The W47 filter finally arrived and I tried an exit slit (gaffa tape 1mm gap on the window of the camera.
Had to remove the ND0.9 filter to get enough light!!
The set-up certainly seems to have potential - there's a significant reduction in parasitic light.
sunspots AR 2905/6/7, Proms and filaments visible
I'll do further trials to see if I can refine the set-up further.
Onwards and Upwards.
