labtech1122 Posted February 19 Share Posted February 19 Hi, I'm wondering if any one can help me, I've just started imaging through my telescope and keep getting a very strange set of rings on my images with bright stars, the rings move around and change position depending what angle the camera is at. also the stars at the edges look like they are trailing or out of collimation or out of focus or something. im using a celestron nexstar 6slt with antares x0.63 focual reducer, sc -tpiece and canon 650D. 60mm guide scope with svbony sv305pro to guide I've been racking my brain a lot about this and really need help. DSS wont stack them because it cant see stars and when I got it to stack a couple of images it didnt actually align the images it just put them one on top of the other. blue ring (2).CR2 blue ring (3).CR2 blue ring (4).CR2 blue ring.CR2 Link to comment Share on other sites More sharing options...
