Hi all,
A fairly active prominence was visible along the south western limb of
the Sun today. Unfortunately, this means it's rotating out of view but
it was fairly dramatic nonetheless.

What did you do to get a pic like that from a PST?

In the usual way :)
PST + Barlow + planetary camera (Lumenera SKYnyx 2-0M in this case).
For the 3x Barlow shots the extension piece on between the blocking
filter and main body of the PST is removed - something I wouldn't
recommend doing as mine is an old PST and newer versions have an erf
fitted in the extension piece. In order to get around this, a 2.5x
Powermate works in the PST without any issues. Just in case you're
wondering why there would be an issue anyway, the 3x Barlow (in its
original barrel) won't allow the camera to come to focus on a native
PST.
Here's a mosaic compiled from the PST in normal configuration (i.e.
the extension piece left in) using the end of a 2x Barlow screwed into
the nosepiece of the camera...

Thanks for the heads up--I'll see if it's still visible tomorrow.

According to one report I read this morning, it's bigger if anything.
The prom was also remarkably visible and intricate in Calcium-K...
