Fisheye and astro

I'm going back and forth on what I want in an astrophoto lens. I really like the idea of ultra-ultra wide - even wider than the handful of 14 to 20mm lenses I am looking at - but going much shorter than that gets me in to fisheye territory, and fast. Does anyone have examples of fisheye astro they can share to give me some guidance? My camera is a D850 if it matters any.

I have two nikon Fisheye lens...the 16mm for FX cameras and the 10.5 mm for DX. I have done Time Lapse night videos with both..... but these lens cover so much real estate you are going to be including (absent a crop) trees, roof tops, and stuff that will not be wanted.

But, rent one! Give it a whirl before you jump. I am assuming you are primarily interested in the entire Milky Way.

I haven't found much that like in using extreme wide angle lenses for astrophotography. They tend to distort in the corners. And they don't gather much light. For example, a 10mm lens at f2.8 would only be an aperture size of 3.6mm which is rather small, and not collect much light.

They also pickup every tree and rooftop, and light source, all around them.

My fisheyes have no problem gathering light....but you are correct on the fisheye distortion that is present in all fisheyes ...I personally wouldn't waste a clear night of imaging dickering around with them.

They are good for pics like this - taken before ACC BB tournament....and weddings. During a reception I will use two cameras both with fisheyes walking around firing both randomly at people and things without looking through the view finder........you get a lot of crazy photos...most are worthless but a few are wicked good. They end up being some of the brides favorites. But that is when we were doing weddings - nada mas!
