I reworked a bit on the image, noticing that there were excessive noises in outer regions. It turned out to be over weighting of new Ha with only so many subs (25) when fixing stars. I also added a bit Oiii in centre region in luminace bringing out a bit of radiants of Oiii. Earlier mount errors would also have affected overall details but it isn't possible this year now to repeat such massive hours when the weather was so good a couple of months ago.
