Lagoon Nebula - M8 - Two Edits

Good Day To All
Lagoon Nebula -M8
Really bad coma spoiled what I thought to be fairly good data
86 x 300 sec ,ISO 400 ,Dark's & Flats +- 60
Exposure used 7.10 hours , deleted 3,45 hours LP related.
Experimented with different approaches to editing this one , with mixed feedback off course.

I bought a coma corrector last week ,as exited as can be that my coma woes are a thing of the past , only to discover that my SW200P can not accommodate 2" inserts , now I have to save up for a new low profile focuser a real bummer, in the mean time I going to attempt smaller scale targets with the aid of a Barlow to avoid most of the coma errors.
(The Lens Correction Tool in CS6 sorted 75% of the coma errors but unfortunately it does distort the whole image to the extent that it can not be plate solved.)

Thanks for looking.
