Data gathered at home and Wymeswold.

 

Flats  x 20

Stacked in maxim

Registar for align

and PS level and curves + hubble recipe.  No other alterations

 

ant comments or advice welcome

Very nice image. On my monitor there seems to be a very slight magenta gradient in the background, with the left being a bit darker than the right  (but maybe that is due to variations in background intensity in the sky, not errors in flat-fields)

Great image Velvet.  I'm new to NB imaging so still fumbling about but have you tried Filter - Noise - Reduce Noise..., then in the window set the Reduce Colour Noise slider to 100%.  I've found that this helps to reduce the magenta in the stars.

thanks for that, i have only been doing NB for a few months so still fumbling about in the dark

Very nice.

Hi Velvet,

That looks so nice. Lovely stars, dust and wispy OIII.

It looks a bit magenta on here so I downloaded and opened it in PS. It doesn't looks so pronounced in PS but the info tool ( Set 4x4 ) says it is. I dropped Magenta a bit ( -10 )and that left it blue. I dropped the blue ( -8 ) and that left it green ! Then I used HLVG on medium and that sorted it Nice flat neutral background but it is just the Jpeg from here.

I used colour noise as Mike suggested but at 80%. That just leaves the two bright stars. For them I...... left them alone

A well presented image,

Dave.

A well presented image,

thanks for that, so its just my processing that needs to be improved then  i am not surprised as I am still learning all that stuff

I took a copy and had a play too.    As you say even after the Colour Noise Reduction, the two brights were still a bit pink, so I reduced the saturation on the Magenta using the Image - Adjustments - Hue/Saturation function, and that looked like it whitened them up.  Not sure if that spoils anything else.

It does look good. I think the gradient I spotted is actually the presence of dust on the lower left-hand side. It is not so much a gradient over the entire image, but an edge roughly corresponding to the edge of the nebula

Lovely image!

I knew it as the wizard nebula, but indeed, the flying horse now flies high in my mind :-)

Cheers,

Well done that's a very nice Wizard is that.

You can sort the magenta stars by throwing on a selective colour adjustment - select the magentas and play away with the sliders.

[Velvet]

had another go and reduced the magenta

[r3i]

Superb - what method did you use in the end to get rid of the magenta?

[davew]

I knew you'd do a great job of it. Very nice,

Dave.

i just went back in and used the magenta slider to reduce it in selective colour, 2 second job it was as simple as that.  Did not do anything else.  so i suppose simple is best

[michael.h.f.wilkinson]

Very nice. I am even more convinced now that what I mistook for a gradient is actually dust, as the area to the left has various streaks and blotches resembling patchy dust. Very nice.
