Start from Fomahaut (alpha Pisis Austrini) confirm its position by four stars
nearby-->hop to stars 18-->star 17-->stars 15 & 14-->star 12 then long hop to
star 41 in Capriconus (during long hop, I lost 2-3 times due to dim guide stars
and low transparency, I think the bigger 8 x 50 finder scope will be better)
confirm the position of star 41 by bright stars 36, 34 & 35 that can be seen in the
same FOV. M30 far away from star 41 just about a half degree in the direction toward
star 34. At eyepiece 40x, M30 appeared as very faint smudge of light. At 100x
still unresolvable and can't see nucleus.
