You need an front end ERF and I would also use a full cutoff UV-IR cut filter like the Baader either between my eyepiece and the prom filter or between the prom filter and the objective. You will also need a telecentric before the prom filter and have the system running at around F30.
Also, the four little doo-dads are occulting disks of different sizes for use when the solar distance varies throughout the year. The block the suns disk, all but the chromospheric limb.
Thank you. (sigh) So much to learn, so little time.
