Constellation - Sagittarius
Globular cluster
Distance - 35200 Ly

Date - 8/9/12
Seeing - III with poor transparency
SQM - 21.2 (LM 6.3)

EP - 10mm Pentax XW x 153 TFoV 0˚27

Sketch materials - white pastel and ink

Sketch notes
Very low altitude and poor conditions made this another frustrating object to view, could just about tease out individual stars after 20 mins and changing between 7mm and 10mm EP's.
Bright central core evenly spread out with almost mottled 'arms' very much like a spiral galaxy (e.g. M33).
A little more impressive than M69, worth a revisit again next year.
