Description

Imaged over quite a number of nights Messier 7 made an excellent target in between DSO's taking short 5sec and 30sec exposures.  The purpose was to try to achieve the highest resolution in the star field I could with the basic equipment I have (hence the 5sec luck imaging sub's) and pull out the bright M7 stars (hence the 30sec sub's).  I did an aggressive cull on the data to remove any poor frames which resulted in a final 1384 sub's, consisting 998x 5sec and 386x 30sec

Title: Revision 2 - Decon

Description: I restacked the raw data with mulit-band blending to get a slightly wider field of view, and implemented a deconvolution step in the post processing to try to tighten the stars of the core, while still retaining a natural look and feel to the M7 stars.
