Maximum useful aperture for (HA) Solar Scope?

[Macavity]

One can dream...

But without cost limit, I had heard (at some time) about the notion of
a maximum useful aperture for (HA) solar scopes --- Under UK skies?

Is there such a limit? I note claim for "better results" by stopping down
e.g. a 100mm Lunt to lesser apertures --- In conditions of poor seeing?
And why exclude the same question re. White Light solar, I suppose?

Imaging is my primary intention, but more responses are likely here?

have a Quark chris go on you know you want too . the stars the limit mate you could have one of those 150mm monsters with a front mounted ERF of course. charl.

My day to day solar telescope has a 150mm aperture, it's always useable but in the Winter months the low Sun does suffer image stability. By contrast, low setting Sun in the better time of year can produce stunning images. More and more solar imagers are successfully using up to 300mm apertures. For most of us, finance is more of a limitation.

I remember the S@N review, hard to use images to convey visual experience.

As Charl said doesn't look that much better than a good Quark for a lot less money.

Is that enough counterweight

Ah, Charl... A while later, and I might have been "Quarking it" too? It is
undeniable that a Quark + ED APO or long Achromat  yield great stuff.

My "leisure budget" deals in *Astro Pounds*. (£1 Astro approx. UK £400).
But mostly these are dispensed in "ONES" - Except for a Lunt50/B600!

For the moment, I will be concentrating on (my new ED80) based ideas.
But I still have the 90mm Baader ERF filter... Who knows re. the future?
Was there more activity, I might be thinking of a Lunt CaK diagonal...

Still have some ideas (wrigglings?) remaining for my ultimate dotage!

For UK skies the Max useful aperture is about 20mm now, it used to be so much better 2004,5,6 I recall good seeing Day & night 

but then something changed ! , now I max out the odd good day at 150 with a quark , more likely 120 or less but as always 

it’s quality over quantity , give me a good 40mm PST (with some real finesse) over anything really.
