Hi Micko, glad to see you got some observing in last night as I also did, obsrved till 23:30 then the mist rolled in so called it a night.
You must have the original Hartungs, published in 1968, Ngc 5102 is on page 197 of the Malin Frew revised edition published in 1995.
Ngc 5121 has a given mag of 11.5 and Ngc 5121A mag 14.7, I have observed Ngc 5102 heaps of times ,but never Ngc 5121/A, next time i'm out with the 40cm I will give them a try.
Clear Skies Ron
