IC5070 Pelican Nebula

[zeppo]

Hi, last week I had two consecutive clear nights (I was stopped since January because of bad weather! 🤨) so I tried my C8 with 0.7 reducer on this little nebula

It was exactly 5 hours of Ha with ASI2600MM + 5 hours of RGB with ASI2600MC

This is the result, I hope you like it

I think it’s a lovely image.   I like the colour of the Ha signal.  I

Two questions occur to me, @zeppo.  Why is there not more colour in the stars? The answer may simply be they’re not particularly colourful stars. I don’t know. Secondly.  What method did you use to combine the RGB with Ha?

I look at my images and wondered same thing about star colour. I get some blue and some yellow and orange, but no red stars which are the most common. Red ones are dimmer maybe? Zeppo has some red ones  and rest of image is lovely.

Nice image. I think the lack of colour in the stars is just a matter of processing.

Beautiful!

Hi, and thank you for comments!

The poor colored stars are my fault... I have removed stars to process the nebulosity and then I've added them back without saturating them a little bit!

Maybe in the next days I will add also Oiii signal and I will reprocess also the stars

 

[zeppo]

I've added 5 hours (60x300s) of Oiii signal and saturated a bit the RGB stars 🙂

 

[Ouroboros]

Very nice addition.  
 

I meant to ask earlier. What’s your processing routine to get that deep red in the Ha. Mine usually looks like a garish pink. I’d love to shift the colour to the red end of the red spectrum.

I have the same problem if I assemble Ha + Oiii but in this case I've added Ha to the Red channel of RGB so the result is proper red

OK so you haven’t done anything special to shift your red to the further red if you see what I mean?

Lovely capture of an object that usually gets overshadowed by it's more illustrious neighbour. I prefer the original Ha version, but both are good.

No, no shift at all

Thank you Roy

Tonight I've acquired about 7 hours of Sii signal and I've realized that it is stronger than Oiii on this object! so strong that in order to integrate it I had to use only the narrow band signals because with RGB the color result was ugly

Now I do like those colours !
