This is the Cinematic Lens Flare, but modified to work well with auto-exposure on or off. All the screencaps were made with auto-exposure.
To install: Re-name attachment 6 to flare.png and attachment 7 to lens_flare.png (avoid things like flare.png.png). Copy both of those into the "data/textures/common" folder. Download attachment 5 (lens_flare.cfg) and place it into the "data/models/engine" folder.
Also included is attachment 8 (this is optional)... this is a pause screen that replaces the SpaceEngine text to the infamous SEOAEJCFESOAKNAGSRATOCIWOIATPSAWASETUFOOWTROOVUARISGTWLRYTBANVC. The file for that gets re-named to eng-menu.png, and goes into "data/locale". Please only download this if you get the reference.
UPDATE GUYS! So I decided to remove the red circle oval ghose, and replaced it... with, well, um a bright oval which I used to make the screen bright when you look directly at a star it's very bright. I also re-positioned one of the ghosts.
The 7th attatchment is flare.png, the 8th is lens_flare.png, and the 9th is named properly. Look at the first post for where to put them.
