Description

On 6/20/20 I took 14 images of M101 at ISO 1600 and 300 second duration with my Canon Ra camera attached to my Takahashi FSQ-130ED scope. No filter was used for this session. I guided with my 60mm guide scope and a ZWO camera and used PHD2 and APT software. The RAW files were converted to DNG's since DSS does not support CR3 files yet. The resulting stacked image was processed in Photoshop. Again, no flat frames, dark frames or bias frames were used for this session.
