Bright white dots (4 pin heads) coming up in a vertical line from ground level northwest approximately 3/4" apart traveling southeast.

Very distinct bright white solid lights which appeared slightly vertical, rectangular to horizon (4 pin heads; larger than planets, stars, aircraft) coming up individually in a very straight diagonal line from ground level approximately 3/4" apart travelling northwest to southeast. Approximately 8 in number. Within the course of 3 minutes they each disappeared sequentially at the same point roughly 1/3 high in the sky to dead center above me. I was observing stars in the Flint Hills when this occurred (i.e., no one else present). I took pictures with an iphone7 (i.e., obviously an old model) as they sequentially came up but unfortunately flash was on (i.e., can't see black sky/white objects; may be able to photoshop though I tried a couple of techniques with no success). Hadn't intended to take pictures on outing.
