Coma and distortion just too much for me.

Re: Coma and distortion just too much for me.

Ya, was more of a tip than a review. Apoligize for that. I will try stopping it down but at that time I couldn't afford the loss of light sensitivity. I bought a vixen star tracker and that should enable me to stop down with longer exposures.  I'll try to get a photo example of the horrible coma I see in some of my starfield shots. I am new to astrophotography so bear with me in my learning curve.  Other than that this lens performs magnificently.
