Description

This image of the Cigar galaxy was acquired over quite a few nights between March 15 and April 11th. Total time is 33.2 hours with 22 of those hours being 600 second Ha subframes attempting to show the jets. I used the 8" (200mm) newtonian at F/4.7 to yield ~945mm focal length. The field is slightly cropped. Processed mostly in PI using the NBRGBCombination script to blend Ha into the linear RGB. A superluminance was made from all data using a CLS luminance frame (109x 180sec) as reference. The resulting superluminnce was deconvoluted.
