About this image

I captured this data on Thursday 14^th July22 when the comet was at it’s closest approach to Earth and close to M10.

The comet is approx 168 million miles for us – M10 (in the Constellation of Ophiuchus) is approx 14,000 Light years from us.

I used a different combining technique than the one of K2 that I shared here on 10^th July. This current image is made from two files i.e. stacking for the comet and stacking for stars in DSS then both are processed in PixInsight but instead of layering them in Photoshop I used Pixelmath to combine the two files. Plus, final touches in Photoshop & Topaz DeNoise. I like this one better than the previous version because you can see through the comet i.e. the stars ‘behind’ the comet show up better.

Every time I image a comet I learn more – happy days.

Clear skies all.
