M4 (NGC 6121) a large nearby globular cluster in Scorpius
Sketch and Details by Jorge Arranz
Hello,
Here is my sketch of M4, globular cluster in Scorpius, and second nearest to Earth, just after FSR 1767.
It was done from Bonilla, Cuenca, Spain, on 7/18/2009, using a Dob Lightbidge 10″, with a SWAN 15 mm eyepiece, giving 85x and 51’FOV.
