M42 The Orion Nebula

Posted By Greg Bradley
This object captivates every amateur astronomer and is usually the first to be imaged when you get into this hobby.

You never really tire of it as it is so beautiful and dominating in the sky. The whole area of Orion and its bright stars of Rigel and Canopus with the Pleiades nearby is mesmerisingly aesthetic.

I took this image very early in the morning over the last 2 visits to my dark site observatory. Usually around 2:30am at the earliest to 4:30am.

RCOS 12.5 inch at F9, STL11002 with Astrodon filters, Tak NJP mount, CCDstack, Photoshop CS2.

The Small Magellanic Cloud

Posted By Greg Bradley
Another Southern gem. The beautiful Small Magellanic cloud with its
subtle colours. This is a naked eye object at a dark site along with its
nearby in the sky at least big brother - the Large Magellanic cloud.

They are both close to the South Celestial Pole and sort of form a clock in that
you can kind of tell the time by seeing where they have rotated to around the pole.

This is a companion galaxy to our Milky Way.

Canon 200mm FD F2.8 lens stopped down to F5.6.

Sbig STL11002M camera and Astrodon filters.

A rather short exposure HaLRGB 15 10 5 5 5 at -35C!

Taken under very dark skies and very ideal conditions
(and I mean really nice - a really clear, calm, dark, transparent night - now the full Milky
Way has set in the southern skies the night sky is considerably darker).

I had my Tak NJP mount really hopping with under .1 pixel tracking errors - the most
accurate I have ever achieved. Thanks to a few callibration tips I picked up from the Sbig
Yahoo Group plus close and careful attention to the basics.

Eta Carina widefield

Posted By Greg Bradley
Here is a widefield shot of the most beautiful part of the Southern Skies.

The main nebula surrounds the super massive star Eta Carina which is one of the most massive stars known. It has already blown its lid once - hence all that nebula and is quite unstable.

It may supernova at any time and if it did it would be extremely bright in our skies.

STL11000 camera, Canon 85mm FD lens, HaLRGB 30 40 20 20 20, Tak NJP mount, self guided.

Vela Supernova Remnant

Posted By Greg Bradley
This is a wonderful Southern object not often imaged.

Nikkor 50mm lens and STL11 camera HaRGB 15 5 5 5 at F4.5

To get the size of this object in perspective it would be several full moons across and the same setup in one image would capture the bulk of the centre of the Milky Way.

It is quite near Eta Carina - a bit above and to the left. It isn't a visual object as its too faint.

Vela Supernova Remnant

Posted By Greg Bradley
Here is my image of the Vela Supernova Remnant. This object seems to be rarely imaged and there are only a couple of images of it on the net.

It is a huge object and quite dim. Most of the detail though is in the O111 band.
