This is one of my first images of Jupiter, and an overall first attempt at astrophotograhy. I believe that is Io's shadow being cast in the northern hemisphere of the planet (up is south and down is north). I used the following equipment to create my image:
Celestron Edge HD 11" SCT
Baader Click-Lock Star Diagonal & Visual Back
Canon T5i DSLR (Gary Honis Full-Spectrum Modification)
Best of 700 images - Stacked in Registax / Wavelet Filter Applied
My image was taken on June 10, 2017 If you have any questions or suggestions, please let me know. I am eager to improve my skills, in this exciting and rewarding hobby!
Thank you in advance.
