Description

My first time of "Electronically-assisted Astronomy" (EAA),
using EOS Utility and AstroToaster:
1) EOS Utility for remote operations: camera settings and remote shooting,
    self-timer/intervalometer;
2) AstroToaster for "Live stacking" and image calibration. 

A very bright Moon (65~66%) was present throughout the session,
but seeing the galaxy take shape "live" was a lot of fun!
