"thanks for correcting the comments!"

"nice photo, and thorough comments"

"Photoshop: Color was slightly adjusted using Color Curve, to reduce red, which gets really obvious when there is light pollution. Also, the tripod was not very good so the starts were slightly off-circle. So I move them a little bit using layers. Lastly, the trails were not continuous because of the saving/processing time of the camera. I minimized it by turning off the auto reduce noise option. But it was still apparent. I eliminated it by using motion blur option in photoshop."

"This method actually gives better result than taking 14 min exposure, because the sky would still be of 60 secs, but the star trail will be 14 min long."

"Using photoshop, I combined all of them using layers, and used 'lighten' blending option. 'lighten' blending option takes the brightest value from each pixel."
