Five defined AR visible: AR 2842/46/47/48/49. AR 2846 is the prominent small sunspot group to the north east of the meridian.
Ha surface and proms to follow......
Ken you have included some very interesting results from your experiments some of which are striking in a positive way. The Ha features really stand out in some of your images. What programs did you use to go down this path?
Gerard,
I basically went back to processing with Registax 5/6.
AS3! seems to work well for me, I'll stick with it.
ImPPG has a bit more "finesse" and the results may not look as crisp (due to the seeing) but they never - to my eye - looked overcooked as sometimes with Registax.
(The visibility of the filaments/ filaproms comes down to etalon tuning - just off band and contrast adjustment)
