Hi Greg,

In my workflow, I use Starnet++ via the terminal on my mac on each registered master set prior to combining them ie: HA, O3 etc. Any residual stars or artifacts from the process are then very carefully removed with the healing brush or patch tool.

The original layer with stars is then placed over the top so I can blink thru and see if I've missed anything or if any important data was affected by the star removal process.

The RGB stars are then overlaid, usually in blend lighten mode.
Hope that's useful!

Thanks Andy.

I'll try that next time I do one.

Greg.

That is a nice field of view of this large object. I do like though how you captured the luminance within the certain areas of the nebula. I have found it can often really make an image. Framing like a peace sign is interesting too.

Thanks Paul. All in all I am very happy with the performance of the scope.
I think I will have to learn drizzle integration in PixInsight as well using the Proline with its 9 micron pixels.

It’s come up really well Greg, your revised starless version is looking better

Even though there is a little tilt it’s handling the 36x36mm square sensor size really well.
Drizzle integration is a very easy step in the whole pre-processing equation. I’ve only ever used PixInsight and AstroPixel Processor and it’s very easy in both of those.

Lovely image Greg, Looking forward to seeing more.
The CFF gear is indeed impressive.
Cheers,
Tony

Thanks Colin. There was only tilt on this nights imaging. I reattached the camera later on and tightened the rotating focuser and it gave no tilt.

Good to hear about the drizzle being easy.

Cheers Tony. Yes the CFF rocks!

So much superb detail in one image.

There is a very fine little ram's horn or spiral pastry or some such at 3 o'clock.

Lovely.

Thanks very much M and T. I wonder if its at a different distance?

A question - so all of this nebula comes from the star Eta Carina?? Or was Eta Carina formed in all this nebula?
