Since the last 50 years Astrophotography has made large steps.
In the 80s and 90s I was still peering 10 minutes through a guiding eyepiece while tracking an image of an object using Fujicolor 400, and now I take 30 10 seconds exposures which I stack using the same Televue Genesis.

Many amateurs have the same experience.

Sensor technology has made lots of improvements. 6400 asa is now becoming commonplace with fullframe cameras.

What will it be in the 2020s or 30s ?
100k asa or even a million ?

I think the SLR has extinct by that time and completely replaced by mirrorless cameras with liveview which shows instantly the sky as if it were exposed 5 mins at 1600 asa by standards of now.

This will allow active observing goggles which have a live view camera in it which show the sky live but amplified at 30 fps ? In urban skies equipped with improved Hutech filters ?

The same equipment easing daylight viewing planets ?

And lightweight travel scopes such as a 10cm apo of only 1kg (or 20cm truss apos of 8kg, or 50cm compact Dobsons with tracking platforms of only 15kg ?).
