Processing Details: Maxim DL 5.18/Adobe CS4/NoiseWare, Darks only

Object details:

Centaurus A (also known as NGC 5128) is a prominent galaxy in the constellation of Centaurus.
The galaxy is also the fifth brightest in the sky,[11] making it an ideal amateur astronomy target, although the galaxy is only visible from low northern latitudes and the southern hemisphere
Centaurus A is located approximately 4° north of Omega Centauri Because the galaxy has a high surface brightness and relatively large angular size, it is an ideal target for amateur astronomy observations. The bright central bulge and dark dust lane are visible even in finderscopes and large binoculars

At a distance (10-16 million light-years). NGC 5128 is one of the closest radio galaxies to Earth

Object details:

The Whirlpool Galaxy (also known as Messier 51, M51a, or NGC 5194) is an interacting grand-design spiral galaxy that is estimated to be 23 ± 4 million light-years from the Milky Way Galaxy in the constellation Canes Venatici. It is one of the most famous galaxies in the sky. The galaxy and its companion (NGC 5195) are easily observed by amateur astronomers, and the two galaxies may even be seen with binoculars
At an angular diameter of roughly 11.2', it can be inferred that M51's bright circular disk has a radius of about 43,000 light-years. Its mass is estimated to be 160 billion solar masses

Object details:

Messier 83 (also known as the Southern Pinwheel Galaxy, M83 or NGC 5236) is a barred spiral galaxy[6] approximately 15 million light-years away in the constellation Hydra. It is one of the closest and brightest barred spiral galaxies in the sky, making it visible with binoculars.
It is the southern most Galaxy in the Messier Catalog

Name : Pinwheel Galaxy,M101,or NGC 5457

Constellation: URSA MAJOR

Magnitude: 7.86

Angular Size: 28'.8' × 26'.9'.

Location /Date/Time: Telok Sari/19 th May 2012

Mount/Scope/Reducer/Mount control: SW EQ6 Pro/SW 120 ED, 900 mmFL/Meade 0.63 FR/EQDir/CDC

Guider: WO 80 SD@FL 480 mm /DSI Pro/PHD/ Pulse Guide thru EQDir.
Camera : QSI 583 WS @ Minus 10 Deg C.
Filters: Astrodon Gen II LRGB.

Image details: L: 5 x 600 L/ 4xR/2xBx300/2xGx300 Captured using Maxim DL 5.18. . Total 1 hr 30 min.

Processing Details: Maxim DL 5.18/Adobe CS4/NoiseWare. Darks only

Object details:

Pinwheel Galaxy,M101,or NGC 5457, is a face-on spiral galaxyat a distance of 21 Mil Ly away in Constellation Ursa Major.
To observe the spiral structure in modern instruments requires a fairly large instrument, very dark skies, and a low power eye piece

M101 is a relatively large galaxy compared to the Milky Way. With a diameter of 170,000 light-years it is seventy percent larger than the Milky Way. It has a disk mass on the order of 100 billion solar masses, along with a small bulge of about 3 billion solar masses.M101 has five prominent companion galaxies: NGC 5204, NGC 5474, NGC 5477, NGC 5585, and Holmberg IV.

Wah galaxies galore! I can see that you are also very productive on this trip!

[maguro77]

Very nice! Galaxies in our own backyard -- must really try and make a trip to Mersing and see for myself..

[rcj]

love those galaxies Kochu! It was a fruitful trip for everyone! Didn't expect M101 to be that bright. good job! Might have been additional work setting up and drift aligning, but worth it! See you in June?

[Gary]

Good stuff Kochu! Beautiful spiral arms. Thanks for sharing!

[khurram]

Very nice!!

[weixing]

Hi,
WOW! Galaxies hunting...

Hmm... it seem that the M51 is a bit out of focus... must be too excited and forget to double check the focus...

Anyway, well done and keep them coming...

Have a nice day.

[shirox]

very nice kochu!

[Airconvent]

Nice effort Kochu!

[Mariner]

Nice! Alot of black pixels in M101 though but still nice.
