Description

This is my first venture back into astrophotography for 7 weeks since I had hip replacement surgery. I set up my Star Adventurer tracking mount with the Canon DSLR and m1nual 180mm Nikkor telephoto lens. The hardest part was trying to stand up again after kneeling under the tripod to polar align the mount..!! I captured 32 x 30sec exposures at ISO800. These were stacked twice, once aligned on the stars for sharp stars, then again aligned on the comet nucleus to get a cleaner comet image. The stars from the star aligned image were then combined with the comet only image after running StarXterminator on both images with a mask on the comet nucleus to prevent it being treaed as a star.
