Stacked and blended in Photoshop , contrast with Curves

Delta Aquarids meteors shower.
These meteors were capture between 23:55 till 01:17 , and I took 193 shots and only the 9 featured in my picture left a visible trail to be stacked.
On the other hand during the observation period , I captured lots of like small explosions , all over the sky but leave no trail at all , just a with point that vanish in the next frame but those frames are not included in the picture above as they look like a ordinary star.
Best regards
