Rho Ophiucus - 50mm

This is my first attempt at this area. Composition is not ideal but was a bit rushed to beat the clouds. Comments and critique are welcome and will welcome any hints at bringing out the nebulosity around Antares and Rho Ophiucus.

Details:
Canon 60Da
50mm f1.4 USM @ f4.5
ISO800
15 subs @ 240s
15 darks
Aligned and stacked in image plus
Post processing in PS CS4
Mount = EQ5
Guiding with Orion 80mm guidescope and SSAG

Thanks for viewing.

The next time that I have the rig set up I will take a photo and post it but for now I will describe it here. When I am imaging widelfield I piggyback the DSLR on top of the Orion 80mm guide scope which then mounts on to the EQ5. For stability I have a short bar on top of the tube rings which joins the two together. I have a ball mount on top of one tube rings onto which I then mount the camera. The benefit of the ball mount is that it makes it much easier to compose the image in the frame.

I copied the idea from an article that I saw by Jerry Lodgriguss on using Canon EOS cameras for astrophotography (see link below). If you scroll through the images on the article you will find a photo of Jerry's set up which is similar. The difference is that I am using an EQ5, the scope is the Orion 80mm guidescope and I have also installed an additional bar on top of the tube rings to join them together for additional stability.

Link to the article follows. It is a good overview article as well for introducing astrophotography concepts.
