A bubble within a bubble

I agree with Russell

Looking good Greg, it is a rather intriguing object

Yes it does look good upside down. I may change it.

Its a very large bubble as well. Its really a target for the Proline.

Very nice rendition of this obviously difficult object Greg. The colour does bother me a bit as it seems a bit too magenta but I've never seen a shot of it before so maybe this is what it should look like.

Cheers

Thanks Steve. The magenta is the Ha component which is much deeper than what I have seen in other's images which usually only show the blue O3.

that is a cracker of an image Greg - smooth, detailed and delicate.

one of your best.

Gee thanks Ray. I appreciate it.

That's really good Greg. Looks like and ESO shot.

I'm a bit speechless mate. Very well done. A beautiful image to look at.

What a great job! I think it is very weak, I have not seen so many pictures of this nebula like this.

Good one Greg! You got lots of Ha in your image and also the details are very very good, despite the stars that looks not perfectly round. I am surprised by your O3 data though, with 260m @ f/3.8 you should have much more signal IMHO..
About the reflections, I had similar problems in the past and their were caused by the CCD camera windows reflecting back and forth with the filters. When I had the window replaced by FLI with a new low reflective window during last camera maintenance they disappeared. I would check if perhaps SLX offers the same replacement with a broadband multicoated low reflective windows surface. Your telescope is fast and collect lots of light, the sensor is also very high QE so a small percentage of light reflected is easily recorded..

Its not that commonly imaged. Perhaps its because it is so dim.

Thanks Marco. The O111 data is very detailed. Some of that detail seem to diminish during the blend. I will have to look at a possible repro to regain some of that detail. Also there are processing choices in this image. I could easily have made it an all blue type image as it will go there easily. But I wanted more colour balance and the Ha seemed surprisingly detailed hence the more balanced approach that sacrificised some of the O111 detail for better balance.

Thanks for the tip about the reflections. That may be the case although other images I have seen from users of the RHA show similar with very bright stars.

An unbelievably beautiful image, Greg. Simply stunning!
