Thanks Trevor,
Yeah, still risky holding it this way as one slip and the sun could shine through unfiltered and blind them, but I kept a very very close eye on them.
It is pouring rain again now, we only had a window of about 10 minutes total to do this.
Rain with no cloud, that would be good
The sunspot was remarkably clear and easy to see through these little 'Andrews' knockies. But I would've preferred to image it through the ED80. But it was great fun.
