Thank you, I look forward to it too but I'm sure it'll be a bit of a learning curve!

Mike
Thanks Mike, I was aware of the large amounts of ejecta there but couldn't detect it in my raw shots other than the brightest arc. However, upon reflecting on your comment I dug down a bit further and streched one of my longer exposures to the very limit. One that at first glance didn't show anything of interest - and there it was
Definitely no easy task due to Eta's glare but I was able to squeeze a bit extra out so that the ejecta is now visible all the way around, in quite good agreement with the famous ESO images that have shown this earlier.
Image is now updated with the new version. Thanks again Mike

Thank you John, yes the key to this one is to combine multiple images of varying exposure. Thats what I did for the Homunculus itself originally, otherwise I couldn't have got any detail in the core at all, and now I also had to do it for the ejecta but it's definitely worth it.

Cheers

Thanks Dennis I think a proper CCD camera would be better suited to this object, especially regarding the ejecta. But the Homunculus itself absolutely benefits from the many short exposures a webcam can capture. In this case it's very similar to planetary imaging.

All that detail!
Thank you JJJ, glad you enjoyed it
