Around Eta Carina (RGB added)

At the moment I am throwing an hour here and there in the early morning (4am onwards) and have managed 1.5 hours on Eta Carina in Ha. I had some kinda nasty tilt going on so I've just worked on some crops on the top right of the frame where the stars are actually round!

Processing has been a slight deconvolution and some contrast enhancement. Areas a bright enough that noise reduction hasn't been needed, love big bright objects

These are at full res and there doesn't seem to be any loss over Tif or JPEG.

Wow! The left hand image shows the outer H-alpha "beard" or "lion's mane" around Eta Carinae very clearly, as well as a nice Fickle Finger and Thor's Hammer. The right hand image is gritty and needs another ten minutes exposure, but magnificently sharp, showing both the bipolar HH jets beautifully. Top stuff.

Nice one Colin good to see it with a tad more focal length than I get, loads of detail in there

Thanks MnT, you've seen a lot more in there than I have I got as far as the Finger, sniggered and moved on

Not much more than what you get! If you drizzle under average seeing you should be able to get something very similar

Great pics Colin! Very nice detail, esp in the Eta image!

PS: what focal length are you operating at?

I was actually quite surprised at what was there, I took 36 minutes of RGB last night, seeing was not crash hot but I am curious to see how it'll all blend together

The seeing was really good for what I get in Melbourne, got nothing on what others get at a higher altitude than 79m though
Shooting at 677mm, not long by any means but small pixels at 3.8 microns. Pixel scale of 1.158"/pixel. It's comparable to an 8" F/8 with a 11002 sensor in image scale.

Took 12x60s RGB last night under some FAR less than optimal conditions so you'll have to excuse the MASSIVE blue and green stellar rings

After having another look at Peter Wards image, it shows just how far away I am! I'd need to get 20 hours of pretty good seeing to get close to that!

That's ace resolution Colin, though this website doesn't do it justice I'm sure. I did do Eta with the 1600 awhile ago but it's still in my backlog of processing jobs. Horsie next!
