This is old data but reprocessed using separate layers for DSO and stars. A definite improvement I think, considering it's just 16 minutes. This is back in the day (all of 8 months ago) when I couldn't get longer than 60 second subs no matter how hard I tried. Having said that, I haven't pointed my kit at the equator for a while, so we'll see! Looking forward to having another crack at this this year. :)

I'll probably re-do this object with a smaller refractor 'scope later - that will give me a sharper image and a wider field, more suitable for this large object.

2010-02-07 Orion Nebula - Third Attempt

 

12 x 45 second exposures and 3 x 30 second exposures stacked into one image using Deep Sky Stacker

 

One of my first attempts at stacking expsoures. They aren't very long exposures and not a big total exposure time but I'm happy with the detail captured around the core of the nebula.

 

Shot with a Canon T1i at prime focus, ISO 200 with automatic dark frame subtraction on a 10" Meade SN-10-AT telescope. 1016mm F4.

My very first astrophotography trial

 

I took 5sec exposured images, aligned and stacked. I tried to use DeepSkyStacker but then when I find some better ways on GalacticFool web page I did by myself at Photoshop.

The heart shaped Heart Nebula (a.k.a. IC 1805) is an emission nebula approximately 7,500 light years from Earth in the constellation Cassiopeia and is part of a large star forming complex in the Perseus arm of the Milky Way galaxy.

 

In the middle of the heart lies the open star cluster Melotte 15 and the bright knot at the lower right is separately classified as NGC 896 (it was the first part of IC 1805 which was discovered).

 

I have imaged it using narrowband filters, mapping Sulfur-II, Hydrogen-Alpha and Oxygen-III to R, G and B respectively to reveal its details in the Hubble palette.

 

The overall integration time is 6 hours (distributed over 80 subs) - the data has been collected in Kist (close to Würzburg, Bayern, Germany) with a Class 4 Bortle sky.

Messier 3 (aka M3 or NGC 5272) is a globular cluster in the constellation of Canes Venatici. At 34K lights years from Earth, it is about 8 billion years old and contains about 500,000 stars. Nice.

 

Clusters really ain't my thang - I took this whilst waiting for something interesting to get into position (i.e Cygnus). It's not in a great position for my unguided kit, particularly being a cluster, so I had to ditch almost half the subs I took, resulting in 31 minutes total exposure. Nice to see a fuzzy in the top right - NGC 5263 apparently :)

After years of dabbling with astrophotography (with little success), finally rigged up my old Meade 8" LX200 classic with an autoguider, did some serious homework, and came out with this image of the dumbbell nebula taken from my backyard in Austin, TX.

 

The autoguider (orion SSAG) made all the difference as I could get my exposure times way up w/o any tracking errors. It was awesome and tracked perfectly! I used the autoguider and phd running on my netbook to guide the scope and eosbackyard to capture the images (great piece of software). With the scope autoguiding, all I had to do was tell eosbackyard how many images I wanted, duration, and iso and I headed inside to wait it out. 2 hours later all the images were captured and only the processing challenge remained (which I still have much to learn / very different in astro)!
