That is very good information!
I have a SW ED80 and ED120
I have a full aperture filter cap that I can use on both scopes - Thinking to replace the film with OD 5.0 film.
The dust caps on both scopes allows me to place film inside them to have an aperture of 50mm - Thinking to put the OD 3.8 film in these.
Native
ED80 FL600 @F/7.5
ED120 FL 900 @F/7.5
With the 50mm Aperture
ED80 FL600 @F/12. with reducer F/10.2
ED120 FL 900 @F/18 with reducer F/15.3
Camera's will be a mix bag. ASI294, ASI462 or Nikon D600 (APS-C)
