- Hubble Space Telescope Turns 20
Our Hubble Space Telescope is turning 20 this Saturday on 24th April. To mark the anniversary enjoy these incredibly beautiful images taken by Hubble. Spiral Galaxy M81 is located 12 million light-years away in the constellation Ursa Major. Bubble...
- The Firehead Supernova N 63a
It is estimated that the progenitor of the supernova that produced the remnant seen here was about 50 times more massive than our own Sun. Such a massive star has strong stellar winds that can clear away its ambient medium, forming a wind-blown bubble....
- The Rosette Nebula In Monoceros In Ha
The Rosette Nebula with NGC 2244 star cluster in its middle is beautiful. The mass of the nebula is estimated to be around 10,000 solar masses. The cluster and nebula lie at a distance of some 5,200 LY from Earth and measure roughly 130 LY in diameter....
- The Center Of The Nebula Ngc 281 In Cassiopeia - The Pacman Nebula
The NGC 281 Nebula in Casseopeia - The Pacman Nebula, is quite hard to get. The field of view in my picture does not quite cover the whole nebula. I will have to come back on the target with larger field of view using my refractor later. The Nebual...

Messier 52 Open Cluster and The Bubble Neblua, NGC7635
The M52 in the upper center of the image is an open cluster in Cassiopeia with about 200 stars.
The Bubble Nebula in the middle right of the image has a very distinct 'bubble' emmison nebula.
The image is a crop from in the upper right coner, thus some coma in the picture.
