Yesterday I managed to get nearly an hour of lights around antares. 30 second exposures, 5 second intervals with 450D. I have noticed a red glow on the images- is this amp glow? (ISO 800)
Should I allow longer for the camera to cool down between images?
I am using a battery so maybe it's thermal noise from the battery.
NB the actual frame time was longer with the pause for APT to download the frame, but I suppose the camera was still working when the software said "busy" (about 20-30 secs per frame)
Will post a pic so you know what I mean , but not now as in the garden waiting for the clouds to dissipate again
