Boring Omega Centauri due to jet stream blues..

Hello,

Tired of waiting for the jet stream to pass, I had a play with the Pentax *istDS, WO 80mm Megrez II ED Triplet APO and Vixen GPDX mount to grab Omega Centauri (NGC5139) on 16th June.

Capture: 200ASA, 9 x 30 sec exposures.
Process: Align/Combine in ImagesPlus. Cropped, down sampled and Curves applied in Corel PhotoPaint 12. Saved as jpg with 30% compression.

There seems to be slightly more chromatic aberration than a similar image taken previously with my 2 element Vixen 102mm f9 ED Apo, although at f9 the Vixen is slower than the WO f7.

Cheers

Dennis
