Description

I last imaged M5 in May 2020 using my old DSI II OSC (8.3 micron pixels 0.4 Mpx), compared to the resolution of my new Altair 183C hypercam (2.4 micron 20 Mpx).

Seeing was not the best, resulting in poor guiding ~1.5”/px, and I'm not sure my focus was spot on either. Nevertheless, it is better than my last, and deserves to be posted as part of my journey. 


My lies 25,000 LY away, and the majority of the stars are thought to be ~12 billion years old, although younger blue stars are also visible, 'straggling' amongst the old red giants.
