Just started getting into widefield only having a 35mm previously that had a fast focal ratio, I went for the Samyang/Rokinon 14mm f/2.8

My question is has anyone struggled with flares from artificial lights in their nightscapes, say in an urbanized environment capturing a starfield.  Is the Rokinon good or overall bad when it's comes to flaring compared to other fast focal ratio wide angles out there.   Not a great photo only a quick test of the deck first week I owned it, smudgy stuff is clouds but there are these orange rays streaking outwards from street lights.  I tried behind the tree thinking if was shielded should eliminate most or all.   Direct on it's horrible you just see 2 fanned out radius's.    x2 15sec ISO400

Sorry Dave I know nothing of night sky photography though I suspect the issue you described and that which appeared in your pic was perhaps down more to localised atmospherics, thinking clouds smog fog or whatever to a level not much above the roof tops..?

Yeah there was clouds in the distant was about 20% cloud cover night, my regards is to the orange streaks of light radiating out from the center tree there is a LPS street light right on other side, we haven't switched to LED's yet.

Yeah, I picked up on the flaring, though that would seem a lot for a lens to handle before it can capture a clear sky...?  I suspect that light pollution combined with all other possible atmospherics are hard to defeat, though keep trying..(-:  Thanks for posting.

Hmm that's strange. I'm doing a lot of night photos from the city center but have no such streaks of light on any photo.

 

It looks like it it cropped. Would you post the full image? I'd like to see if any of lights was caught at the bottom.

 

On my photos light pollution gives me overexposed part of image just above the city but I can see no streaks. But the difference is I'm taking my photos from over 40m above the ground :) So if I see any light it is way below me, not above. Maybe that's the reason. So my advice would be as follows:

 

The only solution to this high pollution is to point the lens right above the fence to shoot the sky the highest high and then f#&@ those lamps which makes these stamps!!! B)

 

:D

In other words try to to point camera above the highest lamp to minimize the chance for any light streaks or any other artifacts on photos :)

That is pretty interesting. I can't tell if its dust/smog/etc. scattering light towards you, or if its clouds of something reflecting light. Either way, looks surprisingly cool. It is definitely not flaring directly from those light sources though.

Tried off a neighbors balcony and got the tree to completely block that street light and those strange orange streaks are not present.  Not sure what was going on with the first image that street light is on next street over which is about 40-50 meters from the back side of our building.  No stars as it was completely covered was only some heat lightning above the clouds.

rospondek if I knew I wouldn't get in trouble.  I would hacksaw down at least half of those damn street lights, these towns are lit up way to much.
