The 56mm 2" soup can, coupled with the 90mm refractor provided a wide field and plenty of space around the solar disk just hanging there - good for imaging. But I preferred the 26mm 2", which filled the FOV nicely and brought in the sunspot activity well.
But, when I allowed curious students to peer through the Seymour filter at the Sun, I guarded the unfiltered scope, blocking it. At one point, I placed my hand by the eyepiece, and within moments, felt the burning sear of magnified Sun.
