Hi David, Nice image, the spiral arms are quite visible.  Your 136-5sec subs equates I think to a total exposure of 58 sec. the square root of 136 multiplied by the exposure, so not bad.

Thanks Peter. I’m learning all the time about the surface brightness of these objects and what it means for imaging. I will return to a few of my favourites and do longer runs comprising longer subs. I have just bought a new mount for this.
