Here's a reprocess from old data with the ED80. Now I have a bit more experience with narrowband processing I thought I'd give another go at the green Eta I did a while ago.

Full frame is at: http://www.multiweb.com.au/astro/ngc3372_LHaSiiHaOiii_f.jpg [2.4MB]

This time I used the Ha for sharpening only. The lum was made out of the 3 channels Sii, Ha & Oiii so there are more stars and they look a bit more natural. This one looks a bit better I reckon. Thanks for looking & let me know what you think.

I now added an LHaHaOiiiOiii version which I managed to squeeze more details out of. Full frame is at: http://www.multiweb.com.au/astro/ngc3372_LHaHaOiiiOiii_f.jpg [2.6MB] . I think that's the max the data can be pushed too. Not enough pixels left on the ED80/QHY8 combo to get anything more :)

Great work, Marc! One of my favourite observing targets.
Nice contrast between the right-angled dark lane cornering the bright eta Carinae and the milky nebulae on either side. Key-Hole clearly seen just below eta carinae and dust pillars above descending dark lane.

Regards, Rob

I really like the colour Marc, but are the stars slightly out of focus - just a little - or is my problem due to 'morning eyes'? LOL!

Thanks Rob - much appreciated. :thumbsup:


Thanks mate. I also liked the colors better this time.


Thanks Chris. Focus was pretty spot on but the Oiii and Sii stars were slightly bloated. Might be a result of my processing too. The image scale doesn't allow many pixels per star and when reducing the color saturation on the stars I might have dimmed them too much.

Well done Marc.

I probably speak for many others on IIS, but I am constantly both amazed and delighted with all the really good quality images that are posted here on IIS.

That image is just beautiful. Sharp and full of nice details.

Keep the images coming please Marc.

Thanks Andrew. :thumbsup: Yeah it's suprisingly good for a little scope. I'm amazed at the amount of details you can still pick up for such a small aperture.


Thanks Paul.

Thanks Geoff :thumbsup: - glad you like the pics. I'll keep'em coming then :)

Marc,

The updated image that you have posted is superb. I liken that to a classic oil painting.

Excellent work, yet again. :)

I really like both incarnations.. I would say I like the NB colour version more, however the stars look much tighter in the natural colour image.. Hard to pick an overall favorite from two 10/10 images!
