The Rosette - Narrowband SHO

[SpaceNoob]

Hi All,

I have been working on a few targets over the last few months, between good and bad weather. One of them is the Rosette. I was a bit worried that I wouldn't get the last of what I needed but managed to scrape it through before it gets too low.

Image details:
FSQ106EDXIII, FLI PL16803.
SHO, 690:780:600 34.5 hours total, January - March 2016.

Love the scale of this.
Maybe it's just me but it looks a bit flat though, kind of HDR-ish and the shock front transitions appear soft,maybe it's the deep exposure?
Very pleasing colour palatte though :)

To be honest I felt the same lol. I found it fairly difficult to push the SII and bring it all together. This is probably the first attempt I've had in relation to trying something a bit more tame. I think I'll just take my usual approach and see where it ends up. Just need the time to give it another go. Public holiday weekend was a good opportunity to tackle the backlog of subs :lol:

Looks awesome, the flatness as you say could come from being reasonably deep. Maybe it just needs to be over sharpened and then have the contrast put way over what's needed :P

That's a lovely result Chris. The HiRes has beautiful depth to it.
Well done.

Love seeing the Rosette in a huge field like this

Nice job Chris :thumbsup:

I like it too, Chris. It looks best up close.

Cheers,

Hi, Chris,

I'm writing this a day after having seen it, it is so clear in my mind.

I really like the faint, tendril-rich exensions toward 2 and 4 o'clock, and the free bonus object half-seen at 10 o'clock. Well done.

One thing I miss a tiny bit is some of the Ha and SII detail just inside the "blue disc" of the centre. The problem seems to be that they are present and sharp but obscured by the bright OIII.

A great image.

Best,
Mike

Majestic view!

Wow! Very very nice. Pinpoint stars and very smooth. One for the cool wall. :thumbsup::thumbsup::thumbsup:

That's a wonderful image! Impressive indeed.

I have a (possibly silly) question; if you're narrowbanding it (I presume maybe OIII and Ha maybe Hb too) are you using the natural colour from those bands, or do you take some level of poetic licence to rotate the colours into different hues for clarity / separation / dramatic effect?

Cheers

Narrowband tends to a lot of poetic license :P
Take this one, it has she sulphur as red (which is it), hydrogen as green (it's also red) and oxygen as blue (which it is).

Sulphur and hydrogen are both red, sulphur being a redder red :) When just working with Ha and OIII sometimes a synthetic green is made from a combination of the two.

Hi Chris,

one can see how big the Rosette nebula really is - great image of this huge field!
