***caution ***

Don't try to observe so close to the sun with a SCT or refractor, you'll cook either the tube/ baffle or optics!!!!
It's dangerous enough with a Newt, but at least the return beam focusses in free air at the side of the secondary.
If yoy want to do such observing, make up a wide baffle plate which can be held with dowels etc well in front and slightly to the sun side of the telescope and double check NO sunlight is reflecting into the tube before going any further.
Guys, this is very dangerous stuff.....CAUTION
