Sorry, its the Rosette again! 😉 So while the clouds are miss behaving and not allowing me to get some SII, I thought I would see what I could do with my Ha and OIII data. Never processed a HOO image before because I'm still new to Narrowband imaging and this is the first of this data that Ive captured. I'm still learning so be kind, I know Its pretty noisy which is due to the OIII only being 1hr 40 mins worth, I'm blaming the clouds! 😁 But I'm happy with it for a first attempt.

No need to apologise for another Rosette - it's a joy to behold and an excellent first HOO image - certainly better than my first!

I took the liberty of reducing the green in the image and pulling the black point back a tad - makes the blue core region more blue and less cyan.

It also reduced the halos a little.

Hope you don't mind.

No prob's, the blue does pop a little better. Whats your halo reduction technique!? :)

To be honest it varies depending on the image. The halos on your image reduced because I reduced the green and pulled the black point a very small amount. I generally assess the stars in each master and if necessary use a star maks and MorphologicalTransformation in PI on the offending master - usually the OIII. In fact I nearly always end up reducing the star size a little in OIII to match Ha and SII; on the odd occasion SII needs a little reduction but if I've been really diligent with checking focus then I find Ha and SII are very similar.

Its looking more and more likely that I wont be able to gather the data to create a proper SHO Rosette this season so I thought I would have another go at my HOO data. Its definitely less noisy and I personally love the colour's, its a false colour image at the end of the day so this is my artistic interpretation :)

Fantastic Russ, really pleased all is working well.

Thanks Adam, I'm really happy with how its gone for a first dip into Narrowband, looking forward to improving more and seeing what I can do, it would help if we had to more clear nights though! 😃
