Orion 135mm Widefield
22

A fairly wide view of central Orion shot with a Nikon D750 + Rokinon 135mm f/2 lens at f/2 and ISO 1600. 22 x 180" exposures. Shot in the pre-dawn hours of 10/24/19 from my home in rural central Pennsylvania, USA under Bortle class 4 skies. Many of Orion's well-known nebulae are captured including a lot of the surrounding dust.

M42 is blown out...I should have captured a few shorter exposures to blend in.  Oh well - next time.

Clear skies everyone!

Yes, it's a pretty decent performer wide open.  I've heard that bad copies exist that have bad aberrations wide open, so I guess I must have a good copy.

Thanks!  I should have shot some shorter exposures and mixed them in to capture the core but unfortunately I forgot.  Sadly I don't think I can do much about it now.

Re: Orion 135mm Widefield

Good Evening!
Fine Orion widefield...no problem with the blown out core, maybe a bit to contrasty overall.

best regards,

I love the details- is the light pollution there similar to what you can find in the Poconos, a county north of Allentown? I am going there and want to see if it's better than what I have on western Long Island, just east of NYC!

Also, what's the right focal length lens to use to include Betelgeuse and Sirius in the same FOV?  And what about just for the entire constellation of Orion?  Thanks!

In the councils of government, we must guard against the acquisition of unwarranted influence, whether sought or unsought, by the military industrial complex. The potential for the disastrous rise of misplaced power exists and will persist. We must never let the weight of this combination endanger our liberties or democratic processes. We should take nothing for granted. Only an alert and knowledgeable citizenry can compel the proper meshing of the huge industrial and military machinery of defense with our peaceful methods and goals, so that security and liberty may prosper together.
-Dwight D. Eisenhower, 1961

Re: Orion 135mm Widefield

Wonderful and dramatic widefield image David, I'm always amazed at what you're doing with a stock camera, old lens and the modest Astrotrac! Great work!

Cheers,
Rudy
