2013 was sooooo looooong ago, the imaging World
has changed a lttle in 10 years, I guess....not quite as much as when I left the astrophotography game though, for a little over that length of time back in 1988 - 2002, when coming back to it, the changes were astronomical, including a complete change in medium, chemicals/analogue to electronic/digital, star charts and star hopping, to planetarium software and goto!...it was a whirlwind reintroduction....
...but hey, here we are today
Enjoy the re-immersion
