interesting improvement in 5 years

 

 This guy only mention the equipment changes and much longer exposure times. 

Only "upgrading" the camera, the equatorial mount etc, won't make all the quatum leap change.

Something is missing....

He didn't mention LRGB or narrowband imaging, stacking etc

He didn't mention the post processing improvements.

Which is about 50 % of astro photography ( maybe more than 50%) 

btw, the elephant trunk only occupy 1 /25 of the field ( new setup) vs 1/16 ( old setup)

2.12" x 2.12" per pixel (new) vs  1.31" x 1.31" per pixel (old) 

and there is a lot of cropping.

anyways, all of this show his dedication to astronomy
