Start from the tea-pot's handle: stars 34,27,38 & 40 (quite fit in FOV of finder scope)
stars 40-->27--> points to star 22 "the lid of tea pot" or "Kaus Borealis".
From star 22 hop to star mag5 which close to M8,M20 & M21; then hop to stars 13 & 21.
M24 locates at the top of imaginary triangle which has stars 21 & 13 as a babe line.
It couldn't see in finder scope. Center at its expected location and goto eyepiece
,made final adjustment and looked for the brightest path of star cloud. M24 appeared
like very faint s-shape path with some foreground stars. I couldn't observe for
NGC6603 (small open cluster).
Refer to text: a detached portion of Milky way star cloud, size 2-3 times of full moon,
visible to naked eye on a clear night.
