In this image both the Trifid and Lagoon nebulae are framed together, indicating just how very close they are to one another in the night sky (appx 1.5 arc-degrees separated). Because they are located in one of the richest and most dense star cloud structures in the Milky Way, the background behind them appears as a dull brownish "sea" of dust, gas, molecular elements and stars. Located adjacent to the core nucleus of the Milky Way, they are a truly beautiful sight to see whether by observation or by astro-imaging. These objects attract many amateur astrophotographers year after year.
From North America, these two (2) are considered to be summertime objects. They first become visible in March in the early morning hours (just before sunrise), then progress to full evening views beginning in July and continuing through September. They then retreat into the dusk of evening sunsets in early October, and finally disappear toward the end of that month, not to return until the early mornings of the following March. For observers in the norther hemisphere, viewing of these beautiful objects is somewhat shortened by the fact that they reside in the southern celestial hemisphere. They quickly pass from east-to-west each evening on a low trajectory toward the south.
Look for the images, "230625 M20 Trifid nebula", and "240628 M8 Lagoon nebula" to see each with better detail and to read about each ones' astronomical heritage.
