Christmas Tree Prom now

Yes I did..
Sadly, it doesn't work too well.
With binoviewers, the light is split in two, so you only get half the light in each eye. This makes the image dim. Furthermore, an optical corrector, like a barlow, is required to bring the image to focus. The 1.6x optical corrector that comes with the WO binoviewer doesn't work with the PST. I also have a celestron ultima barlow and that didn't work either. A 2x barlow which can screm onto a binoviewer or eyepiece just like a filter is the only one that would work for me.
After all that, I found the image wsn't very bright and I preferred the view with a single eyepiece. The binoviewer works very well in larger scopes on the moon and planets but not so well with the PST I'm afraid. It might work better with a larger aperture solar telescope where one has also got more control on the range of focus.

Great sketches, Dee, Jeff and Michael.
I was wondering, were you able to see a series of filaments resembling a river flowing from the Christmas tree prominence?
eg
See a sketch from a guy here that keeps a daily track of solar activity with sketches he makes with Photoshop.

Sadly no , I would have sketched it in if I saw it.
Just saw a filament inline with the prom , which is in each of my sketches
and it changes shape with each sketch. If they are not big enough to see I could upload close up images.

Thanks for pointing that out, I wish it was clear today to do more solar work.

That's an excellent sketch you have linked there Vagelis.
Any idea what scope/filter the person was using?
I only saw a very small part of that filament in the PST. Sounds like that guy has a fairly narrowband h-alpha filter.

I also failed to notice the filaments. They might have been too dim for the 40mm-ish aperture the three of us are using -- or it might just be because we were too busy dodging clouds to notice them.

I have seen a photo image of the filament network on an American site.
Well done to the Greek sketcher for catching it.
