Hi. I'm still learning with my DSLR.

I need to know why is there a glowing reflections in the sky with this shot. How do i avoid it?

Tq.

Post the EXIF of the photo, and it would be easier for us to tell you.

My guess is because it's over exposed.

EXIF data would be nice, as stated. What aperture were you using? Also, did you use your lens hood when you took the shot? A lens hood is used to avoid glare from light sources. When not using the lens hood, it is possible for bright light sources (yes, even at night...especially at night) to cause lens flare and anomalies. I'm not sure this is the case here but was trying to rule it out.

Sorry. I forgot about the EXIF data. I've updated the post.

I never knew about using the lens hood at night.

Always use your lens hood. The lens was designed to use it and will yield better images when it's installed. The only time you should not use the hood is when using a filter that won't allow the hood to be attached at the same time.

While in many shots the difference with or without a hood will be minor, it will prevent many little anomalies from spoiling an otherwise beautiful shot. It can even affect the sharpness.

If you can, return to the spot and try the same shot with your hood installed and see if the problem goes away. If not, try a smaller aperture...say around f/8 or so.

Hope that helps!

Thanks navcom. Very grateful.

With the aircraft moving left to right or right to left, you would only see one color...red or green....not both. Both are only seen when the aircraft is coming directly at you....in which case the lights would appear blurry but relatively stationary.

If you look closely, it is possible they match up with light sources on the ground via lens flare...but it's not certain.

I had the same problem, and I found removing my UV filter fixed it. I think it is to do with the light reflection of the light from the front of the lens onto the inside of the uv filter back into the lens. Here is a picture I took where the same thing happened, look at The Ritz and the reflection of that

yup, that is because of the flare. Attaching a lens hood will solve the problem.

I don't agree, about the lens hood, yes a lens hood will help for bright light sources from the side but not for light from the front. If you look at my picture you will see that it is a reflection cause by a longer exposure that gives the bright light enough time to bounce as explained previously and cause a reflection. That would also explain why the ghost image is upside down
