What kind of image to you get with an Orion Glass Solar filter?

I bought an Orion Glass solar filter for my 80ED recently (second hand).

It produces a nice white circle.

I'm sure it would highlight a venus transit, if that would occur again in my lifetime, but other than that, it is just a plan circle (I'm mono imaging).

Is there something that I need to know about imaging with this filter that will show me more. I know it's not a PST or Lunt or anything, but I expected to see more than just a white disc.

Do I need to do something different to get more out of it, or are we just living in times where there is no solar activity for the moment?

We're still waiting on Cycle 25 kicking in...until then there is little in the way of white light detail visible.

As Merlin says above,we are waiting for the next solar cycle to kick in,then you will see what are called facula,white markings on the suns surface!
Faculae are the precursor to the appearance of sunspots.
Other than that white light filters don't give you any further detail.
Fingers crossed for some good sunspots this time around.
Cheers
