Messier 82 (also known as NGC 3034, Cigar Galaxy or M82) is a starburst galaxy about 12 million light-years away in the constellation Ursa Major. A member of the M81 Group, it is about five times more luminous than the whole Milky Way and has a center one hundred times more luminous than our galaxy’s center. The starburst activity is thought to have been triggered by interaction with neighboring galaxy M81. As the closest starburst galaxy to Earth, M82 is the prototypical example of this galaxy type.SN 2014J, a type Ia supernova, was discovered in the galaxy on 21 January 2014.In 2014, in studying M82, scientists discovered the brightest pulsar yet known, designated M82 X-2.

Telescope: Explore Scientific AR127 127mm f/6.5 Achromatic Refractor Telescope
Camera: Full Spectrum modified Canon SL1
3x Barlow tube
ISO: 1600, 1/160 second
Single shot, no stacking.
We were looking for a better telescope to upgrade our 5″ Celestron f/10; something sharper and faster.
We decided to go with Explore Scientific AR152 152mm f/6.5 Achromatic Refractor.
If clouds allow we will take it for a test ride. Stay tuned.
We were having trouble with our Celestron CS5 f/10 telescope, it is not fast and collecting a decent amount of data takes hours.
We have an Orion 80mm f/5.0 Refractor that came with the guiding kit. We decided to give it a try as imaging telescope.
We started with 30 seconds at 1600 ISO and 17 light frames. Since this is just for testing purposes, we didn’t use any flat, dark or bias frames.
Considering this is just a $130 telescope, it works much better than we expected. We are planning to get a better refractor telescope to replace our slow Schmidt-Cassegrain telescope.

Messier 5 or M5 (also designated NGC 5904) is a globular cluster in the constellation Serpens. It was discovered by Gottfried Kirch in 1702. Spanning 165 light-years in diameter, M5 is one of the largest known globular clusters.
At 13 billion years old, M5 is also one of the eldest globular clusters in the Milky Way Galaxy. Its distance is about 24,500 light-years from Earth, and it contains more than 100,000 stars, as many as 500,000 according to some estimates.

What would an astrophotographer do, if he forgets the camera adapter for the telescope?
Connects camera with a lens to the mount and takes wide view shots of the milky way…

We have several fruit trees in the backyard, and we were losing fruit flowers due to lack of pollination. We were doing it manually on lemon trees with a small painting brush.
So we are so happy to see this visitor in our garden 🙂
Finally got a decent picture of the Jupiter with 3 of its moons (Ganymede, Io and Europa). Taken with 8″ Newtonian + 2x Barlow. Jupiter was next to a half moon, so details are a little bit hazy.
