About this image

The 3rd Interstellar comet discovery in a clear sky, with Celestron 11 partly obstructed by the dome wall. I used SharpCap 4.1 plate solve software and goto coordinates (from MPC). For image analysis with Astrometrica, I entered values from MPC (rate and direction of motion). This worked well and the comet was found close to a star trail at magnitude 16.9. I believe it is getting brighter now.
