The rotation of Jupiter
In this sequence of 4 frames of Jupiter on the night of 9-10 August 2021 in a time span of about 30 minutes it is possible to see the rotation of the planet.
The north pole is at the bottom left.
This is M 27 or NGC 6853, also known as the Dumbell nebula.
It is a planetary nebula in the constellation Vulpecula, a rest of a supernova explosion.

My first photos of Jupiter
Here are some photos of Jupiter, in black and white; if I had a color camera, the vision would certainly more impressive.
The first two photos were taken on June 27, 2021 at 01:18 and 02:07 Italian time and it is possible to see the rotation of the planet which takes about 10 hours.
M 57 or NGC 6720 is a planetary nebula in the constellation of Lyra and it is what remains of a supernova explosion.
At its center there is a white dwarf which is what remains of the supernova core.
M 13 or NGC 6207, also known as the Great Globular Cluster in Hercules, is an object made up of hundreds of thousands of old stars and it lies in the halo of our galaxy.
It has a diameter of 145 light years, a distance of 22000 light years from Earth, and an apparent magnitude of nearly 6, so it is almost visible to the naked eye.
M 100 or NGC 4321 is a spiral galaxy of the Virgo cluster at 55 milion of light years from us.
In the photo near to M 100 you can see NGC 4323 and NGC 4328 that are two satellite galaxies of M 100 as highlighted in the second photo.
M 66 is a galaxy in the Leo constellation and it is a spiral galaxy with a weak bar.
It is located at a distance of 31 million light years and is moving away from us with a speed of about 700 km/s.
