Description

I returned to my 85mm lens and shorter exposures:

258 60sec exposures through the Astronomik LPR_CCD clip
298 120sec exposures through the Astronomik Ha clip

I could not find a name for Sharpless 2-151, so I dubbed it the Raptor nebula after the 2019 NBA champions - looks a lot like their logo!
