Stellar Shot of the Week
SVX90T - Lagoon and Trifid
Tony Hallas caught this mind-blowing shot of M8 (Lagoon Nebula) and M20 (Trifid Nebula) in Sagittarius with his SVX90T. Both of these objects are emission nebulae and sit somewhere between 4,100 and 5,200 light-years away from Earth. M8 was discovered by Giovanni Hodierna in 1654 and M20 was discovered by Charles Messier in 1764.
