This globular is almost as big on the sky as M13 and a delight to observe visually, as well as to photograph.
Taken in April 2015 from Austerfield with the ODK12 and an M25C in a series of 60sec frames unguided. This was during the setting up of the ODK, so not a bad overall result looking back on the log. A re-processing of the subject to favour the colouring of the stars, in Photoshop. No flats or other calibration used.
