C 92 Eta Carinae Nebula

[Grumpy John]

Lucky to have a cloud free night so I had another play with the Dwarf Mini.

The Eta Carinae Nebula is one of the largest and brightest nebulae in the sky, four times larger than the Orion Nebula. It contains the unstable hypergiant star Eta Carinae, which may explode as a supernova. The nebula shows incredible detail in narrowband imaging. The nebula is approximately 8,500 light years from Earth.

So how do you work out how many light years we are looking at at the diagonal? I suppose you would need the exact angle of view as well as the 8500 ly distance. Maybe forget all about it and just enjoy the image.

[Grumpy John]

The sizes and distances do my head in, I'm just amazed at what I'm able to capture with the Dwarf Mini.

You are producing amazing images with that little device Hans. How do you locate the objects and does it track or does it take and combine multiple images.

You must be very pleased with it.

[Grumpy John]

Looking like a clear night again, so there may be more images forthcoming.

[wigz]

I’ve been trying to get Milky Way shots but can’t seem to get a clear night with no moon that works for me.

[Grumpy John]

Yeah, it all has to line up doesn't it.

All looks fascinating John. All coming together for you.
