Eta Carina

Posted By Greg Bradley
Eta Carina is the 2nd most beautiful nebula in the night sky after M42. One day that star is going to Supernova. It will be quite a view when it does. One of the most massive stars known.

3 x 30 seconds. Dark sky site, Nexstar 11 at F6.3, Nikon D70, ISO 1600. Images Plus, Nikon Capture Editor.

NSW Australia in Jan.

A very dense area of the Milky Way with lots of stars in this region and Caldwell 091 huge open cluster nearby as well as the Southern Cross and the Jewel Box open cluster.

I intend to get better shots as clouds moved in and interrupted a beautifully clear night.

Omega Centauri

Posted By Greg Bradley
A favourite target of mine. Quite a spectacular sight in the Southern Hemisphere. It is also getting quite high in our skies here later at night so I will get better shots next trip.

Nexstar 11 GPS, 3x15 seconds, F6.3, Nikon D70, ISO 1600, Images Plus, Nikon Capture Editor.

NSW Australia at a dark sky site in Jan. Clouds moved in as I started to image this so I only got a couple of exposures.

Vanuatu Milky Way

Posted By Greg Bradley
Found a compact flash card full of photos from my recent trip to Vanuatu in the South Pacific that I had mislaid.

This one turned out nicely, no moon and very clear skies. Tropical tree in the foreground, about 85 degrees temp, lush green tropical island.

Nikon D70, 50mm Nikkor Lens F1.8, ISO 1600. Camera lying on the beach in coral sand for a tripod!

Eta Carina

Posted By Greg Bradley
Nice clear skies last night, no moon.

Taken from my backyard in Sydney.

Nexstar 11 GPS,unmodded Nikon D70 with Denkmeier SCT OCS fitted to a Vixen 2 inch adapter mounted on a T mount adapter to my camera = approx. F5.(takes me 5 minutes to mod my D70 just don't have the Baader UV/IR filter just yet).

6 x 30 seconds. Processed with Nikon Capture Editor version 4.2.1. ISO 1600, exposure compensation 5+, white balance direct sunlight, noise reduction on.

Aligned and combined with Images Plus adaptive addition set at 2.1.

I also shot this at F6.3 with a Meade focal reducer for a comparison. I can process that later and post the results for a comparison. At F6.3 the shots are sharper but not as bright.So its the old higher speed versus tracking situation.

Also shot Omega Centauri and the Jewel Box which I can post later.

Clear skies,

Greg.

Omega Centauri

11 x 20 second shots. Nexstar 11 GPS, Nikon D70 at F5. From my backyard in Sydney.

May be going to a dark site later in the week and will take more of this one there.

Jewel Box

Posted By Greg Bradley
Here's another one.

The Jewel Box is a fabulous sight at a dark sky site with binos. The stars are not only different colours but different distances making a very 3D effect.

4 x 20 seconds, my backyard in Sydney, Nexstar 11 GPS, Nikon D70 at F5.

M42

Posted By Greg Bradley
8 x 30 secs, 3 x 45 seconds, Nexstar 11, D70, Nikon Capture Editor version 4.2.1, Images Plus. Lovely clear night, fairly good seeing.

Didn't frame it as I would have liked but turned out not too bad. I like the new features in the new version of the Nikon Capture Editor, only problem is the files take ages to save now for some reason. But it pulls out the red better in an unmodded D70.

Clear skies,

Greg.

Centaurus A Galaxy

Posted By Greg Bradley
Fabulously clear night, no moon, dark site in NSW Australia, almost zero light pollution, stunning views of Milky Way from horizon to horizon through the zenith. Stayed up all night imaging with Nexstar 11 and D70 about 16 degrees C - cool, but not cold.

Here's one of those shots.

Centaurus A galaxy. 7 x 45 seconds, ISO 1600, Images Plus and Nikon Capture editor. Really needs say 20 x 45 but it turned out not too bad.

Clear Skies,

Greg.

Eta Carina

Posted By Greg Bradley
Hi, I posted a similar shot last week but this is higher resolution and taken from a dark site with more exposures.

24 x 45 seconds, Nexstar 11, D70, Images Plus, Nikon Capture Editor.

47 Tucana

Posted By Greg Bradley
2nd largest globular cluster in the sky. 47 Tucana is near the Small Magellanic Cloud.
A bit low in the sky at the moment it will be at its prime in July/August.

8 x 20 seconds, D70, Nexstar 11, Images Plus, Nikon Capture Editor, dark sky site.

Clear skies,

Greg.
