Thank you all!! I agree that it's most likely a movement of the scope. Good to know!

Hi, thank you for the welcome! Actually I joined Stargazers Lounge because I was very surprised when I found this shape in a photo, and thought that someone could have an explanation. I also think that it's a satellite, but not sure. The shape appeared in just one photo of a series taken every 90 seconds. By the way, I read your great description of Eta Carinae area, I'm also discovering this wonderful region and (in my case) making some photos. Should I join another group to talk about imaging? I'm not sure if this forum "Observing - Reports" is just for visual. Cheers!!

Hello! I'm doing astrophotography just since a few months. My equipment is a Celestron 9.25 SCT, with an f/6.3 reducer, a Nikon DSLR camera and an intervalometer. Yesterday night I made a series of 90-second photos of IC2944 (the Running Chicken Nebula). The brightest star there is Lambda Centauri. When I reviewed the photos a few hours ago, I noticed in one of them a very strange image, immediately to the left of the star. I wonder if someone can tell me what is that. I'm attaching two consecutive pictures, one "normal" and the other showing the image. They are unedited, I only converted the photos from NEF to JPG. Thanks.
