7/3/2023 1:11AM, SE Portland (near a street light), SharpCap Pro, ASI183MC Pro, Celestron 8SE, w/L-eNhance Dual Band Pass 1.25" Filter, 240 second exposures, 111 gain, 10 frames, FITS file opened and stretched with GIMP, resized to small png.

Had 2 main issues.

    1. Was tired and

    b). PHD2 calibration was sub-optimal.

Also hit some issue with SharpCap plate solving that sent my mount into a place where the focuser was hanging up on the DEC motor (AVX mount). Had to restart the setup and polar align again.  After 10 lights for the Iris Nebula, I was happy to call it a night.  Several things to do differently next time.
