Nice photos! I love the colors of Andromeda galaxy.Heres the image of M31 I took last year. and M42 at late winter.

I'm just amazed of what my mobile just did!
I've captured from Madrid the Orion constellation near dawn with my phone. I putted ISO to 1600 and obturation time to 1/2 sec. This is what I got:
After that I used the digital zoom of the phone and took this close-up of the orion belt:
Do you see that in the middle of the frame? Have a closer, look zooming in the same image:
That blob is the Orion Nebula!!!!
I really couldn't believe it, so I took several pictures like this one to see if it was just a random fluke a little stronger than the sorrounding noise of the image but the same structure apperead in all the photos. Also the position is perfect match if you compare with a celestial chart.
I've imaged the orion nebula hand helding my phone, without telescope nor any extra component. Just my phone
Maybe is not that amazing but for me it has been an emotional rollercoaster.
I think the lower blob in the image is Iota Orionis and the upper the nebula itself
nopeWow, is the last photo HDR?
The meteor must of course be higher than the ice layer to make a halo like that. Noctilucent clouds form between 75-85km altitude, and the meteor's explosion might very well be higher than that. But since the light source is quite close, the rays coming from it are far from parallel when they hit the cloud layer, compared to sunlight or even moonlight. Correct me if I'm wrong here, but I think that means it should decrease the size of the halo.
The halo is formed when light gets deflected through countless ice crystal, and the minimum deflection is just under 22 degrees, regardless of the distance to the light source. Like the rainbow, distance to the light source doesn't matter. But I think the ice crystals of noctilucent clouds are different. Perhaps such halos wont form through these crystals. Perhaps we don't know. I'll ask an expert for his opinion.
