can anyone please tell me what causes this object to appear in images. I have a 14'' sct meade and attached is a atik 383l, this is in images using hyperstar, 6.3 focal reducer and normal imaging. I have read others have this problem but no answers. any advice would be most appreciated
regards J G
Unlike the normal SCT star shape there's a diffraction pattern affecting the stars, showing as spikes, so maybe the artifact is from shiny wires/cables. Try shifting the cable positioning...
