Lagoon Nebula (M8) at 3 F-Ratios

Hi All,
Well with this welcome period of good seeing and clear nights Ive taken M8 at three different F-Ratios 1. 10" SCT at F-10 (with an F-6.3 reducer would have been a better choice) 2. with the ED80 at F 7.5 3. With the ED80 + reducer to F-5, all 6 Min. Exp. at ISO800 with the Canon (modified) and using CWB (will do the same lot using AWB for a comparison, weather permitting, close-up and wide views each have their interesting points, I like the F-5 best but would be better with the other nebulosity to the east of M8 showing, still trying to get it without overexposing M8.

cheers........Jim
