Two versions of the Rosette Nebula

[CCD Imager]

I accumulated around 14 hours of data in the Rosette, all in narrowband and decided to present two different versions. The "red" one is produced from bi colour HaOIII and the second a Hubble pallete from Ha OIII and S2.

I'm torn between the two, but having accumulated so many golden blue images in recent times, I am more taken with the red, more true colour image.

Taken with an Askar 400 and ASI6200 over several nights in the last couple of months.

Looking at them both back and forth trying to make up my mind I am at a stalemate, interesting how two images of one target can be so different from each other.

They're both beautiful!

Love them both, but the second one stands out for me….superb…👍🏼

Both look good to me, Dont you just luv the Askar 400 and ASI 2600 combi.

Hi Simmo

Indeed a great combo, but dont tell any one Ive got the ASI6200

The 2600 is also a very nice large sensor camera too

Cheers

My bad. I should learn to read. lol

Both are beautiful images. 

i personally prefer  the natural “red” color, but the second alternative color palette shows better details. 
Well done!

[glafnazur]

Both great images but definitely the first one for me, to my eyes it seems to have more detail.

Both are really nice but as a direct head to head I'd plump for the first, red version. I think it has more depth and an almost 3D feel.

Super clean image. Very nice!

Wonderful images. Very pleasing to look at - both of them.

Really lovely stuff. I never get on with false colour as well as I do with with natural so I instinctively go for the HaOIII. However, the Hubble image has more striking local contrasts.  Obviously these extra contrasts are provided largely by the colour but I wonder if some of that extra contrast comes from brightnesses as well?  You could find out simply by putting the Hubble over the HaOIII as a luminance channel.

I'm guessing you removed the stars and replaced them with ones with a softer stretch? They are admirably tiny! Another thing I like is the way you've gone deep on the gasses but not turned them into something solid-looking. They still look gaseous.

Chapeau!

Hi Olly

We are out of the false colour season, so my attention now is to natural coloured galaxies

Although there have been advances in Astronomical Equipment over recent years, I think that image processing has really improved moreso. I now treat an image as three different components - Object, background and stars where all three can be processed independently. There is a blur area between really faint objects, for example outer galaxy regions and the background, but with clever selections, this can be addressed too.

The smaller stars are partly a consequence of seperate processing (which is in fact very little), but also by using a full frame camera and the resultant image is scaled down. Should you look at a 100% version, the stars look just the same as small sensor cameras. Stars should be pinpoint to reflect their true nature and what is seen visually, I dont like big fuzzy blobs!

Merci beaucoup!
