Hi Paul
Just double check you have the VISUAL film and not the ASTROPHOTOGRAPHY only film. It sounds from your description that you probably do have the visual, but it is worth a check.
The BAADER AstroSolar™ Safety Film comes in 2 flavours, neutral density 3.8 and 5.0. The 5.0 is for visual and astrophotography; the 3.8 for astrophotography only. I have both for the Vixen 4” f9 refractor and when I fit the 3.8 astrophotography only filter, I first move the Sun’s disc out of the FOV with the 5.0 visual filter, then whilst Narelle shades the objective with a square of plywood, I remove the 5.0 and fit the 3.8.
I then carefully move the ‘scope until the limb of the Sun just appears in the FOV and that indeed is very bright. This way, I can centre the Sun in the FOV without risking my eyes as I then make the finer movements with the keypad whilst watching the image on the computer.
Cheers
