The Fetus Nebula - It's really small

Recommended Posts

It's really small, but it does look like a fetus. If you zoom right in and squint a little.

Serious though, processing is not great, im still not happy with the star field which looks great in L but seem to alter when i add the colour. I think they may be slightly out of line. Can you stack the colours using an L as a ref frame?

Any tips for helping the colour out would be appreciated, although the colour in the teeny nebula looks pretty accurate?

Thanks guys.

Interesting little planetary.

Your RGB layers are certainly not well aligned. What software are you using? If ever my basic stacking and calibrating software (AstroArt) does a poor job I re-do it in Registar which is infallible. Not cheap, though. I find that AstroArt likes the red channel to be the reference channel when aligning RGB. I don't know why it prefers this but it does.

Olly, I can get the left top part of the histogram lined up but not the curve on the right which is what i think causes the imbalance (this is the brighter part of the image?)? I use PS6 but I'm not sure what to adjust to sort it?

I use DSS and use  a reference frame each time. Should the red channel be the preferred one to use?

EDIT - I've restacked using a L frame as ref and it has made a difference. I'm quite pleased with this one now!! Thanks Olly.
