NGC 7006 or Caldwell 42. Globular Cluster in Delphinus. This is one of the most distant Milky Way
Globular Clusters at about 135.4 kly from the Sun. L subframes were 45 seconds and taken Aug 18,
2006, while the RGB subframes were 30 seconds and taken Sept 10, 2006 with a DSI Pro II on a C8NGT
(8" Newtonian f5 and ASGT mount). The total exposure in L:R:G:B (in min) = 18:17:15:11. Color
balanced achieved using G2V star and correcting for exposure times. Captured with Envisage,
calibrated and sigma combined in Iris with other processing using PixInsight LE and Photoshop CS.
