1000mm on an APS-C gives a FOV 78x52 arcsec for a Canon and a couple of arcsec more on other brands.

1000mm on an a full frame like a 1Dx gives a FOV 127x85 arcsec. 2000mm would give you a sun that almost filled the frame.

I used a Sony a200 (APS-C) on an ED127 for a FOV of 85x57 to shoot the TOV.

Yes Baader film gives a grey/white image. I have one for my C8. I also have a couple of Thousand Oaks glass filters for my ED127 and ST80 which give a yellow image.
