Couple of items: Just got the 5d3 back from lifepixel - both IR and UV cut have been removed. Suggestions for testing are appreciated.

For the solar eclipse I am planning on using the same system I used for the annular eclipse - filter holder w/ solar film. For exposure 'jumps' from from pre to totality and back, planning on using the Custom mode to preset the jump about 10 stops.

Would love to figure out something for the full spectrum 5d3 - have the tamzooka which has a 95 mm thread or the 70-200 with a 2x for 400mm reach and a 77 mm thread. I know a 77mm H-alpha would be pretty spending at these diameters...... IF you could find one and IF it wouldn't result in the sensor being fried. Any thoughts, suggestions, would be appreciated.
