I installed the 16 inch Newtonian over the weekend with Keith's help and tonight I was able to get it on the moon.

Jupiter

Same Data, better processing



6/22/2019

This is my first Jupiter, taken last night with the 14 inch RC-Cassegrain telescope. The seeing was not very good.
It was taken with three 1 minute movies of over 1000 frames each. The 3 frames were taken with Red, Green and Blue filters respectively.
Then the each of the movies was stacked, removing the fuzzy frames. Only 20% of the frames were kept.
Then I did some image enhancement (image sharpen). This is where I need more work and need to learn more about how to use the software to bring out the detail.
Then the 3, stacked and sharpened images where then merged into a color image.
The GRS (Great Red Spot) is clearly visible in the lower right.
