Solar Activity 23rd July 2021

[Merlin66 (Ken)]

The current activity in CaK and WL

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......

Just a quick Ha image to show some of the activity!!

[Tropo-Bob (Bob)]

Nice images Ken!

[Merlin66 (Ken)]

Thanks Bob, appreciated.

[Eris (Gerard)]

A very nice comprehensive set of Ca K and WL images Ken. Looking forward to viewing your Ha images when they come through.

[Merlin66 (Ken)]

Playing around with different processing, so bear with me...
Not the "usual", but interesting.
(I think I'll go back to the AS3! and ImPPG)

[h0ughy (David)]

SoME nice stuff there Ken, and some pretty ordinary results as well.

[Merlin66 (Ken)]

Yeah, I have to agree David.
Next time........

[Eris (Gerard)]

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?

[Merlin66 (Ken)]

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)

Onwards and Upwards.

[Eris (Gerard)]

Yes. So many variables to contend with Ken. The results were worth the effort.
