Hi Greg,

Thats a really nice image, can you clarify where this is? I havent heard of the Omega Nebula.

Cheers

Chris

Thanks Chris.

It is also known as the Swan Nebula and it is near the Eagle Nebula and Lagoon Nebula.

That's beautiful Greg. M17's one of my favourites. Such an interesting shape. Well done.

Thanks Marc.

Yes it looks a bit like a lobster. Um, lobster - I'm suddenly hungry!

mmm, I dont know, given the quality, somethings missing............

Buddman (Adam) · #16 19-09-2008, 10:25 PM

That's just great. I thought my images of the swan were OK but now I realise what I was missing.
Beautiful.

Hi Fred,

This was actually the first image I took with the scope/camera.The first were with an STL and I haven't processed them yet.

The first night's effort I found out focus was slightly off. Later nights the focus was spot on. In fact the focus does not seem to shift night after night which is a real plus - like the RCOS, so I am happy about that.

Also binning O111 at 2x2 seemed to be counterproductive as it gave too much leakage and a wide glow. 1x1 seems better for O111. How do you find O111 taken from the suburbs?

Greg.
