M8 Lagoon, M20 Triffid and M21 Cluster in Sagittarius
A narrower widefield of the area around these objects.
The image was captured with the older Canon 55-200mm f4.5/5.6 zoom lens operating at 200mm F5.6.  The lens is really not up to the job, 4mm play in the lens assembly when racked out for 200mm has affected the image badly.

Capture details: 20 x 300s ISO 800 Canon EF55-200mm F/4.5-5.6 II USM 200m@f/5.6
