About this image

This was a stack of 5 * 180s guided exposures with a Nikon D800 iso 640 with noise and long exposure reduction. Telescope was Celestron CN-8 f5 Newtonian. A Baader field flattener was used. Mount was Skywatcher EQ6 Pro.

Used to do a lot of astrophotography years ago on film, guiding by eye, so now getting back into it using digital means and auto guiders. This was one of my first images. Stacked manually and processed in Photoshop.

Amazing. so much nebulosity! Wow. Are the diffraction spikes all natural or augmented? A great capture. well done.

Thank you. The diffraction spikes are real, courtesy of the secondary mirror vanes. Some people like them, others don't!

I live in a dark sky site, so it was good to see so much nebulosity come out.
