Here are a few more images taken with my c9.25 with a Quark Combo on a 3X telecentric with an Orion 0.8X focal reducer.

Re: On the sun's limb on July 25
Hi
I was doing a first test of a 90mm F6.7 with a 4x Barlow and a straight through PST Etalon on the 25th late morning in the UK.
I could see a region, sort of hedge prominence, on the bottom right for me, about twice the height of the spiricules.
Does that sound about right based on images taken?
Andrew.

Re: On the sun's limb on July 25
Hi, Andrew
If I remember correctly, what you are describing sounds like the prominence in the 3rd image down which I spotted in the lower right of the sun's disk on my screen. I often reorient my images right side up no matter where they actually are on the sun. Did you take any images of that prominence?

Re: On the sun's limb on July 25
Hi
I am still in modding mode. Mainly baffling out stray light as I like good contrast.
I have a little QYH but failed to find focus in one try on the PST some time ago.
I might try sketching.
As the Sun is dynamic its just nice looking.
My one bodge try on the 127mm at F30 what I could see was comparable with an image on here, maybe a little more contrast.
When the first cheap Chinese refractors came out lads were web-camming the planets.
You would look through the scope one week and see the images the next.
They were less sharp, contrasty and colourful than what you re-called seeing.
