Thanks for your comments - there's been many times where I've just wanted to throw it all in, but when you capture an image you're proud of, it can reignite the enthusiasm.

I agree it looks black clipped, but that's just because it was a 60-sec exposure in jpeg. There simply weren't enough exposures or a long enough exposure to lift the background levels any higher. I didn't adjust the black point at all.

Once the control issues are taken care of DSO is great because you just sit and watch TV or talk to friends while things are going on. You don't need to sit there constantly.
Keep it coming.

I don't really enjoy one more than the other at the moment, it's just been a matter of convenience that I've done deep space imaging in the last month or so. When I go to a dark sky site (pony club or mudgee star party), I don't take my planetary scope because it's just too big and I don't want to sit at the scope all night - I want to set up a run and then go and chat with people.
Also, when I'm at a dark sky site, that's the place to do deep space imaging (for me). I can do planetary imaging at home where light pollution doesn't matter.
I can't see myself doing any imaging for the next couple of months unless I can make it to a Pony Club meet, I'm just going to be too tired and in need of sleep!

It's only the S/N that suffers with the short exposures of bright objects like eta Car.

Interestingly, on the first night (and with my previous Orion Nebula image), the white balance was set on "Custom", where it's fairly balanced for daytime images. It did though, to make the images very blue.
On the second night, I set the white balance to Auto, and Eta Carinae came out much redder than it would have it was still set to custom. I didn't modify the colour temperature during RAW processing so that's how it came out of the camera.
