Have you used the z 135mm f1.8 Plena? What do you think of it?

If you would like to post, you'll need to register. Note that if you have a BCG store account, you'll need a new, separate account here (we keep the two sites separate for security purposes).

Has anyone tried Plena for astrophotography?
Yes, does great, pretty sharp corners, colors are good, did great on imaging the comet. I would not spend the dollars to be a primary astro, would instead get the Rokinon, But if you want the Plena for everything else it does great.

Thanks for responding, Commodore. You had nice shots of Comets and Aurora lights, but I mean shooting DSOs (like the Orion nebula, etc.). Is the Plena probably not enough reach? BTW, which Rokinon lens (z) is good for Astro (DSO)? I do have z20mm f1.8 for nightscape.
 
If I remember correctly, there are a number of forum members who use the Rokinon 14mm f2.4 manual focus lens for astro milky way shots, and other wide angle dark sky photography. It's a F-mount lens that is being used with the FTZ. And is very sharp in the corners with little coma. I've never tried it but hope to acquire one.

Perhaps this lens is what was being referred to?

The rokinon 135 is the perfect lens for DSO! Many Astro folks use it. Go to Astrobin website and do a search for 135mm lenses And nebula.

Also, you will not get any DSO with a single exposure. I sent you an image from a friend, used with permission, 135mm length, mirrorless body, but tracked, with Eq mount, and stacked images. Probably 20+ 15 second images including lights and darks. A YouTube search Rokinon 135 Astro will give you hours of info.

Yes, I plan to get a star tracker.
