... seen one, seen 'em all!     Well, some might say that but I disagree.
When you observe more than just the few big bright ones, you discover that every globular cluster has its own quirks.
In 2009, I set myself a challenge to image all the Milky Way globular clusters possible from my home located at latitude 32 degrees South, in country NSW, Australia. The majority of the clusters were accessible with the exception of a few that were too far north and several that are highly reddened by intervening interstellar dust and are only visible with specialised infrared detectors. My imaging device, the GSTAR-EX CCD Deep-Sky Video Camera, is sensitive well beyond the normal visible light range (400-700 nm) out to 1.1 micron (1100 nanometres), so a lot of the moderately reddened clusters would still be within its grasp. I had already imaged many globulars in my general imaging sessions, so the list was completed fairly soon after on 12th April 2010.
In the initial list I left off two targets because I could not image them from my observatory but in mid 2012, I set up an 8" f/6 reflector in a paddock which allowed me to image very low to the north to a declination of +50. This brought NGC 6229 and Messier 92 within range. After imaging these two, it only left one on the list that was too far north... Palomar 1 at declination +79.
More clusters are being discovered but all are being found with IR detectors and so will be out of reach of my imaging system.

The list I followed contains 157 Milky Way globular clusters known at the time of writing.

The table containing all the data is rather large and would not present well on a mobile phone or small screen device, so just a few examples are accessible on this page.
For those viewing from a PC here is the full data table with a link to each of the object images in a pop-up viewer.
