However, APM (7.7-15.4mm)--approx 66°, and TeleVue (3-6mm)--approx 50°, make zooms with constant apparent fields from one end to the other.
And Leica (8.9-17.8mm) may be wide enough for you (57° at low power, 78° at high).
But I agree with you--zooms work pretty much the opposite of what you'd like to see.
Though, I could deal with a zoom that went from 21mm to 7mm and 80° to 100°, but that won't ever be made.
But only 40° at the long end and 57° at the short.messier 111 wrote: ↑Wed Mar 01, 2023 12:59 am hi jeff ,

I like the eye relief and the field of view.

you are right Don, but I find that for the sun and planets when I travel especially it does the job.Don Pensack wrote: ↑Wed Mar 01, 2023 1:03 amBut only 40° at the long end and 57° at the short.messier 111 wrote: ↑Wed Mar 01, 2023 12:59 am hi jeff ,
