I was more focused on White Light today but did get a few snaps with HA using the Esprit 150.

Terrific series, Simon.
Beautifully contrasty surface and delicate, wispy proms.
Cheers

I did indeed. Looks like a lot of places all over the US over the next couple days have 5/5 seeing according to Clear Sky Charts

Simply gorgeous, to resolve all those fine wispy spicules and proms is such a delight to see :bow :hamster: it happens rarely in the UK :(

Great results, and beautifully processed.
Can you remind me what's the Hɑ filter used?

I remember read somewhere Simon uses a Gemini. Sorry if I am wrong.

Is the Proms etalon redundant? Since I do see proms quite well with the Quark chromosphere

Not specifically, there is a trick to using a prom version or should I say if the bandpass is 0.9 angstroms and above.

The idea behind it is, fainter proms are more.... prominent. :mrgreen:

I find I get much sharper results, especially when going for prom animations at the expense that surface details will just look off band. There have been 1 or 2 occasions where for some odd reason, the surface has come on band.

Generally speaking, I dont push people into getting one for proms if you dont have a specific use for it.
