Regarding the filters. There were no colored filters used.
Both the 600mm and the telescope had Solar filters of two different types.

The 600mm had a Thousand Oaks Optical Type 2+ Glass filter that belonged to a friend. It was actually purchased for his 6" Newtonian telescope but he was out of town for the eclipse and not using it. It just so happens to fit almost perfectly over the lens shade of the 600mm. It was a bit loose so gaff tape was used around the edges of the metal filter rim to hold it snugly over the lens shade.

The telescope had a 4.5" Off-axis R-G Solar film filter that I own. Purchased also from Thousand Oaks Optical. Part#RG-13750A
