Bob,
Yeah, I expose for the best surface histogram then another exposure to pick up the fainter proms (without washing out the brighter prom portions).
Run the SER files through AS3! and tweak a bit in Registax6.
I then bring the surface image into Corono (
http://sweiller.free.fr/Softwares/Corono/) to crop the exact surface edge. (You can do the same with the proms if needed)\
Finally in PaintShopPro open both images (the surface and the proms) -select the surface and copy as a new selection onto the prom image - centring as best you can. At this stage you can use PSP to flood fill the surface to give some colour.
Save the final image - job done!
I regularly use the Continuum filter on my white light set-up - definitely improves contrast. I've also tried the OIII filter, which actually works very well.
The Ha DSO filters can also be tried (when you have a full aperture solar filer or Herschel wedge) they see to give a steadier image in the red seeing conditions.
My seeing down here at the coast is marginal at the best of times (OK for spectroscopy but a PITA for imaging). Full disk solar imaging is all right, but zooming it with the PST Mod gives below average results.....such is life.
