Whoever told you that the Rokinon was better than the Nikon for star trailing has no idea what they are talking about since star trailing comes form the movement of the Earth and has nothing to do with the lens. If you want to be able to take photos with your camera and a wide angle lens of the sky without star trailing (and longer exposures to get more of the stars in the photo), you need a mount that will follow the Earth's movement. If using a camera and not a telescope, iOptron makes a mount for this. The link for it is below:

Get the rokinon, it is good enough and you will not have spend a fortune, only problem is QC.
I do a lot of Astro and use zeiss 15, 18, and 35mm love them all I have also used 14-24 and am selling it now for 1200 another excellent lens.

Do you think that the OP didn't know the proper terminology for corner aberrations? Technically, I believe its called astigmatism, but there are several types including some that look like trails. And while premium Nikon glass is a tad sharper in the4 central portions of an image, it gets that by sacrificing edge and especially, corner sharpness. Roki has much better IQ in the corners.

Let me give you some other things to consider: since your main target is meteors, that is a numbers game. The more shots you take the better your chances. But you also improve your odds by using a wider lens since it takes in a broader view of the sky. And a 14mm takes in a LOT more sky than a 20 or 24mm.
You can also use your D800's intervelometer, set it on a tripod and let it do it's thing for hours on end. Hope you have some good luck finding an interesting foreground element. Show us your results after, please.
Also I'd recommend you ask the experts in the UHH Astrophotography section.

Great e-book on night sky photography in general and Milky Way in particular. By Royce Bair. Well worth the few bucks for the ebook (pdf).

You have confused what star trailing is. Go back and read my post.

Read my reply. I said I think the OP doesn't know the proper term for astigmatism or coma and is calling it trails.

Photo mark why is the Milky Way not visible at this time?

The Milky Way is present all year but the Galactic Center is only visible March-Oct It rises and sets during daylight hours the rest of the year. The Galactic Center is what you want to photograph

I use both the Rokinon 14mm and the Nikon 20mm F/1.8G ED for astro work on my D800. If I could pick only 1, I would use the Rokinon. It just captures so much more sky.

You're welcome! Mborn's response is exactly right; I should have been more clear in meaning the galactic center will not be visible. You will still get some excellent shots, just try to find a nice foreground subject to enhance them. You might even try your hand at light painting a foreground subject!
