Hickson 44

I have long known about the ARP (The Atlas of peculiar Galaxies) but not known a great deal about the Hickson group of galaxies. 

I was playing with Stellarium looking for a new group of galaxies in Leo when I by chance found the Hickson 44 group. As always I do a google search and check out what the group looks like and found the group to be really interesting. 

The Hickson 44, after Canadian astronomer Paul Hickson, is a group of gravitational bound four galaxies about 100 million light-years away in constellation Leo. Other names include the Leo Quartet and the NGC 3190 Series. The two spiral galaxies in the center of the cropped image are edge-on NGC 3190 with its distinctive dust lanes, and S-shaped NGC 3187. The bright elliptical galaxy lower right is NGC 3193 the spiral in the center lower portion is NGC 3185.

Just 12 x 3 minutes per RGB filters used here, so a little over and hour and a half in total. Very pleased with the result and definitely worth a deeper view next spring.

Moon May 24, 26th & 28th

Taken over 6 nights 24th, 26th & 28th May. What a difference a few days make.

All taken with the 130 EDT and using the 2600mm. Not a planetary cam especially at 6 frames per second. A 2 panel mosaic for each image and an AVI run of 5minutes, Best 65% using Auto stakkert and Registax 6.

 

 

Pillars of creation

Holy smokes, sometimes you just need to stop in your tracks and just behold the beauty, majesty and enormity of space. M16, The Eagle Nebula or more commonly known as "The Pillars of Creation" is probably the most iconic and well known images of deep space and the legacy of the Hubble space telescope. First captured by Hubble back in 1995. The "Pillars of Creation" is a star forming cloud of Hydrogen gas 90 trillion kilometers wide. The tiny section in the centre of my image resemble fingers, stalagmites of condensing clouds of Hydrogen gas and dust forever reaching into the darkness, lying deep within and not visible to conventional cameras are eggs or incubators of newly formed stars ready for birth in a few hundred million years.

The Black & White images here are my own from my 130mm telescope and cooled camera capturing light at the frequency of 656.21nm or the wavelength Hydrogen Alpha.

An ever increasing zoom into my image reveals the Pillars in all their glory. 

Seven hours of data capture this incredible region.

Finally I get to compare my image to the most celebrated of Hubble's images. With Hubble's final cost of around $10 billion and my modest set up around a million times less I don't think I have done a bad job.

M10

Well a first for me I think in the last couple of years. 3 yes, three nights clear in a row and no work, so that means 3.00am finishes each night. Tonight would be night 4 but the forecast is for clouds. Oh well it was good while it lasted.

The plan to continue with the E nebula when it rises high enough so for now just 45 minutes 15x 60 sec RGB on M10. It will soon disappear into the tree so very limited time on target. I have a high fence around the house and a tree at due south so anything this low that rises is only visible for an hour or so.

Not a great result but happy I managed to capture it.

Arcturus

Arcturus

Located relatively close at 36.7 light-years from the Sun, Arcturus is a red giant of spectral type K1.5III—an aging star around 7.1 billion years old. Arcturus has moved from it’s Hydrogen to Helium burning to Helium to Carbon phase. The star cools and changes colour to more orange & red, as it cools it expands and sheds the outer layers.

It is about the same mass as the Sun, but has expanded to 25 times its size and is around 170 times as luminous. Its diameter is 35 million kilometers.

Size comparison.

M12

Not a great deal has changed in the 259 years since its discovery by French astronomer Charles Messier, M12 is a densely packed cluster of hundreds of thousands of the galaxies very oldest stars estimated to be over 13 billion years old, bound by gravity this cluster is 75 light years in diameter or about 435 trillion miles in length in comparison that would be approx. 74,000 yes seventy four thousand times the size of our own solar system of planets.

It took the new horizons probe 9.5 years to get to Pluto so that would mean it would take another seven hundred thousand years before it arrives at the majestic M12.

This image is an RGB combination of 20 x 120 second exposures using all 3 filters so a total of 2 hours combined data, processed in PI.

Considering this for me is very low down and just above the fence line I am very pleased with the result.
