Well I haven't been on Astrobin since the crash, so here is the first of many "Catch up" uploads. If you're wondering what I have been up to, I have been primarily posting my astrophotography through Instagram. You can find all of my recent work and blog posts over there.

I can't wait to catch up with many of you guys, feel free to say Hi
