Good work Nic !
The last day or two showed amazing clarity of the sky, not sure if the seeing was perfect as I did not check the seeing indexes on meteoblue.
I was wondering about the filters you use, maybe it is too much ? Not sure if uv-ir filter is needed.
Christian Viladrich says the Oiii filter (narrowband) gives the best chance of revealing the granulations. He posted that comment on one of the recent posts. Also if you see his book, Solar Astronomy, he mentions the Oiii filter many times in the book.
Just the cost of the Oiii filter is a consideration though !
If only we can borrow the use of this filter for an inexpensive amount, for when you can image ! That would be great.

Re: WL two spots York UK
Thank you all very much indeed: I’m thrilled to bits to achieve SPOD!
James yes it’s a Skywatcher Evostar 80
Thanks Magnus I’d read that a combination of uv/ir and solar continuum filters worked well in a Herschel wedge and seen photographic comparisons so went for that before I bought the Solar Astronomy book! In this one post there’s a further 2 filter suggestions… however do we keep up 🤯😂
It’s great fun getting to ‘know’ you all,
Cheers,

Re: WL two spots York UK
Magnus,
It’s an OIII filter like used for nebulae, right? Screws into an eyepiece? I read somewhere in the past they could be used with satisfactory results. I hear TIO filters are good too.
