M8, M20, M21, M28, M22
It has been a long time since I observed the Sagittarius area at Dunford. Today the teapot is still behind my neighbor's building until about 10 o'clock.
My first target is the long coveted Lagoon nebula, M8, which is roughly equidistance as opposite of Sigma to Lambda. I saw apparent nebulosity around the area about half a degree with open cluster NGC 6530 on the side. Going northwest about 1.5 degrees, Trifid nebula is an easy target,
Continue going north is the open cluster M21,
The next area of interest is around Lambda, 0.8 degrees northwest is the M28,
Going northeast until meet the line extend Tau & Sigma, the magnificent M22 locates. It overwhelms M13 if it locates at zenith I believe.
Oops! it passes 11, I have enough! tata!
P.S. I was wondering why everything looks dime until I realize I forget to remove mirror clip in front😡
P.S. I dig out a OIII filter, seeing Lagoon and Trifid through OIII filter are just amazing!
