Will there be a continuation in HST?
Please, kindly provide the approximate focal length.
This is clearly not 360*2.9 = 1044 mm! More like >2000 mm?

The mirror's focal length is 1050mm, and with a 1.15x paracorr, we get a focal length of 1207mm according to plate solvers. And just by looking at the frame shape, you can tell it was cropped.
