Deep Sky images abound!

Eta Carina nebula in Ha (16x300s).

It is only recently (January) that I finally installed my first ever set of narrowband filters. They are installed on my William Optics Megrez 90mm with ZWO 1600MM camera. Recently I have taken some time to process a few shots from this, and Eta Carina is one of these.

Here is a relatively straight forward exposure but which looked particularly stunning I thought, when I saw the initial result. It is 16 exposures of 5 minutes each, all using a h-alpha filter.

Check out the hoops, knots, holes of the nebula. Fantastic I think. There’s a couple of crops to show you some more detail close up.

There is is not a lot of processing done on these images. The fantastic contrast comes from the wonderful dark skies of Astro Observatories Western Australia’s dark sky site.

Another deep sky photograph I have been working on recently is the below LRGB image of Messier 46 (whicn includes the planetary nebula NGC through the same equipment.
