NGC7023-F7

I decided to remove the Hyperstar for once to try my hand at some prime focus imaging with the 11" Celestron EdgeHD. I was after some planetary captures (Venus), but I had software issues(Sharpcap). Unitl I had them fixed, Venus had set in the West. So before the clouds moved in, I decided to capture some quick Luminance filtered images of NGC7023, the Iris Nebula
