Let me know what you guys think. This is a stack of 13. This was my first attempt at stacking and really my first real attempt at Astrophotography. All CC is welcome
This was shot with
Canon 6D
ISO 6400
30 sec at 2.8
13 frames

I like your second image best . WF captures sometimes show alot better detail . Also there is a bright blob to the far right in your image i am trying to figure what it is . Looks like the LMC but the SMC isn’t in the picture and i think you have to be way south close to equator to capture those . Whats your location ?

I think it did not stack well. It may be Antares. On a different note Is there any techniques to remove the greenish tint at the horizon line. It seems to be on all my photos but I am having trouble cleaning it up.
Thanks

Anything on the horizon is probably distance light pollution if your pointing towards a city area . But that blob i'm talking about looks pale gray and too large for Antares . So it maybe some type internal flare or reflection of something from your camera or lens .

That spot moves in line with all the other stars as I flip through all 16 shots. If it was a flare I would think it would not move with the stars but could be wrong. Here is a un edited shot from the stack

The bright spot to the right is Jupiter. Saturn is on the left edge of the Milky Way, and Mars is a bit further out to the left of the Milky Way.

Forgot to comment on the green glow before. It's something called "Airglow", and is caused by oxygen and nitrogen atoms that have been excited by the sun's rays during the day. It occurs all over the world, not just near the polar regions like the auroras, and is one reason the night sky is never totally dark. I've had photos where the green glow dominated the entire sky, and thought something was wrong with my camera or white balance or something. Before I found out it's something that's actually in the sky, I tried lots of post-processing adjustments to try to get rid of it, without much luck. It's something that's actually there, not a problem with your camera or technique. (But I still don't like it!!! -?)

If you want to find out more about it, just Google, "airglow in astrophotography" and you'll find lots of links to sites that explain it.

No dumb questions just dumb answeres sometimes. It was shot at 2.8. They were 30 sec exposures and a stacked 13 of them
