Here is just under 2 hours integration (116 x 60s) on the owl and surfboard using a TS quad at 460 mm. APP again doing a wonderful job knocking away effects from three LED street lights pointing at an angle to the scope. After HSL tool, I did treat the background in PS afterwards, and reduced stars a little since my APO has oil filling between the objective doublet causing sever spikes on bright stars and has to be returned. I'll be curious to see how the star reduction works in APP when it comes, one less thing left to do in PS! These are 12 bit OSC data, no flats, no filters (aside form

UV/IR cut on the camera itself).
