Equipment:

Processed with PixInsight 1.8.6 from data provided by Terry Robson which he describes as over 18 hours of imaging on a "small telescope in an undisclosed location in the Southern Hemisphere."

Description:

NGC 1698 is a very large (about 74 light years in diameter) open cluster/emission nebula located 158,000 light years from earth in the Large Magellanic Cloud (constellation Dorado), which is only visible from the Southern Hemisphere. The data used for this image was provided by Terry Robison, who gathered the data with a small telescope, which he describes as being located in "a very dark site in an undisclosed location somewhere in the Southern Hemisphere." His total imaging time for this data was over 18 hours and took several years to accumulate. The image that you see here was processed by me using PixInsight 1.8.6 astroimaging software and is part of a workshop of the Astro Imaging Channel (theastroimagingchannel.com).
