If you are anything like me, if someone states they have an image with five galaxies visible in it, I immediately think of either part of Markarian’s Chain or Stephan’s Quintet in Pegasus. The latter fits in a field only 4 arcminutes in diameter. This image is a little different, spanning more than 250 degrees of azimuth.
Taken last year while on holiday on Benguerra Island in Mozambique, this is a stitched panorama of 10 photographs using a Canon 70D at 22mm focal length, ISO 3200 and F/2.8. The images were combined in Microsoft ICE and processed in Adobe Lightroom. I am quite pleased how this turned out given it was only my second attempt at an astro-panorama.
So how many galaxies can you spot? Three are simple, one is a little trickier and the final one might require a closer inspection of the photograph.
The reality is there is far more in this photo than a quick glance first reveals. Rather frustratingly, Astrometry.net refused to work on either the Panorama, or the individual frames, so I sat with iPad in hand and Sky Safari 5 Pro, and worked my way across the image, tracing out the constellation patterns (rather tough with so many stars to pick from) and picking out any DSOs I could find. Turns out there were quite a few!
The table below runs from left to right on the image listing each of the identified DSOs. I doubt it is fully exhaustive. If you spot one, let me know and I will add to the list.
