Some more fun with the Nifty Fifty and Vixen Polarie. I kind of went absolutely nuts with Carinae before full moon comes around the corner hehe 😁. The new darksite really opens your eyes to the nightsky! Had to discard afew subs unfortunately, every darksite will have the odd cloud floating about but nailed at least 36x2mins. This little polarie tracker sure still stands up to its name as a no fuss portable tracker and plan to mod it up abit more later on in the near future like I did the star adventure I used to have.

This is a wide field capture. I really like this subject, has a lot of interesting features/structures. Captured with LRGB, Ha and OIII filters. NGC 2359 (also known as Thor’s Helmet) is an emission nebula in the constellation Canis Major. The nebula is approximately 3,670 parsecs (11.96 thousand light years) away and 30 light-years in size. The central star is the Wolf-Rayet star WR7, an extremely hot star thought to be in a brief pre-supernova stage of evolution. It is similar in nature to the Bubble Nebula, but interactions with a nearby large molecular cloud are thought to have contributed to the more complex shape and curved bow-shock structure of Thor's Helmet.

Today's post is on 'Starquakes'
We've heard about Earthquakes right? A star quake is quite similar.. Well what happens in an earthquake is that the surface of earth shakes due to sudden release of energy in the Earth's lithosphere that creates seismic waves.
A star quake is a phenomenon that occurs when the crust of a star undergoes a sudden adjustment, analogous to an earthquake on Earth.
As of now we've only heard of quakes on Neutron Stars.
The causes can be of two types :- (1) As the neutron star loses angular velocity due to frame-dragging (an effect on spacetime, predicted by Einstein's general theory of relativity, that is due to non-static stationary distributions of mass–energy) and by the bleeding off of energy due to it being a rotating magnetic dipole, the crust develops an enormous amount of stress. Once that exceeds a certain amount, the shape adjusts itself to a shape closer to non-rotating equilibrium: a perfect sphere. (2) Huge stresses exerted on the surface of the neutron star produced by twists in the ultra-strong interior magnetic fields.
How dangerous would it be for Earth?
Scientists detected a star quake in 2004. The quake, which occurred 50,000 light years from Earth, released gamma rays equivalent to 1037 kW in intensity. Had it occurred within a distance of 10 light years from Earth, the quake would have possibly triggered a mass extinction.
Astronomers have found five new supermassive black holes in the centers of galaxies. When galaxies collide and merge with each other, it can force their supermassive black holes close together. While models predict this would happen, it has been very difficult to find these giant black hole pairs until now. The combination of data from Chandra, WISE, and the Large Binocular Telescope led to this bumper crop of black holes. This discovery could lead to a better understanding of how giant black holes grow.

SH2-104. Is a small structure seen (in the upper left of center) With a lot of nebulosity around it that can be picked up with a field telescope. I struggled a bit processing this as there is a great deal of stars in the field! But I think I am pretty happy with the end result! Tell me what you think?
