The Spiral
A clear night last week let me sample the Spiral Planetary Nebula NGC5189 with the brand new 98% enhanced coating on Zamar's mirror after faithful duty of the original for 23 years. Thanks to Wayne Sainty in Foster.I kept an unusually high number of subs (around 70% ) as the tracking seemed pretty stable. So 492 Subs @ 5 sec ISO 2000 stacked in DSS and edited in Star tools and Gimp. Cheers W
