IC 1805 the Heart Nebula

[Dmack1]

The second half of my Sunday night.

 

This was about 4.5 hours of 180s subs with the ASI 2600 MC, SW 80ED and the L-enhance.

 

Again same data processed two ways;

 

Straight RGB

 

A HOO, this time trying to Keep the Ha red

 

I really want some RGB stars to drop in.

 

C&C Welcome and appreciated.

Both images look great. Can't you extract the stars from the RGB image and save them to insert in the HOO image?

Very nice pics.

thanks for that. when I say "straight RGB" I mean the L-enhance data has been processed just as RGB instead of extracting the R=Ha G=Oii and processing as such. and i extracted the stars before splitting channels. So the stars are pretty essentially same.

 

Sorry for the confusion.

The second process as HOO is great, is that one of the pixel math dynamic mix equations using the extracted channels ?

The second process really showcases Melotte 15.

Great stuff.

Thanks Bryan,

 

Unfortunately I have no idea what "pixel math dynamic mix equations using the extracted channels" actually means 🤣

 

It was the R extracted and called Ha, G extracted and called Oiii (B discarded) and then mixed using SHO_AIP script. I cant remember exactly what the mix was except R =Ha100% then G & B were 100% Oiii and a very small but different (<15%) of Ha in with them. Very much trial and error to get what I wanted.

 

But it has come out nice I think.

This is what Bryan is referring too. You'll find all the info on here.

Thanks for that. I've read it 3 times and unfortunately I still have no idea what it actuallly means.🤣

Both images are great, have you tried a reducer with your scope to frame the whole Nebula?

Thanks for that Martin,

 

I have a 0.85 reducer and indeed the actual frame included the fish head. But something happened between lights and flats meaning I had a huge horrible dust bunny in the vicinity which would not calibrate out and also some overlap that meant I had to crop to what it is.
