Hi all,

Just sharing the fruits of my attempt at the Cat's Paw Nebula.

Data collected over several nights from Paddington in Brisbane and adding up to exactly 19 hours of integration.

Data from Ha, S2 and O3 Astrodon's 3nm filters was blended to create the final image.

Any feedback, suggestions and even rotten tomatoes will be appreciated and valued.

Crikey, that is astounding!

Do a starless version?

Slawomir, that's absolutely superb. Extremely sharp, fine tracery of dust lanes. No hint of sharpening artifact. Beautifully processed.

It might be possible to wring a tiny bit more OIII out of it, but there's very little there, and the way you've presented it is true to the object.

Well done.

Great work!

That is an interesting take on this object. I really like the feathery detail in the full res image and there is a very minor amount of speckle in the back ground. The full res does look just slightly blurred, but the detail level is more interesting. The large resolution image looks very sharp and I think a better way to show the image. The colour contrasts seem nice in the smaller presentation. Well done. I like it.

Really nice Slaw, lovely fine details that are the hallmark of good NB images and the framing gives it a rather dynamic look, like it is a large creature changing direction under water, perhaps a big jelly fish or giant squid. The colours are vibrant and fiery too, very Rickesque there ...ready to print straight onto metal or glass I recon

Dude, that's awesome. Only thing that could make it better imo is more data, which of course always makes things better ;-)

Thank you all for your very kind feedback. The truth is I did not expect that I will manage to "paint" this nebula with different colours - it is very strong in Ha, has decent S2 but it turned out there was very little signal in O3.

It is not as sharp as I would like; there was some backlash in the mount in both axes (now I have eliminated it) and on a few occasions dew started forming on the lens - I will need to get dew controller and a heater...

I was hoping to collect more data but some people of this forum (not pointing fingers at anyone in particular...) have been recently buying telescopes and good weather has ended

Starless version? Hmmm, for some strange reason I actually do not like very much starless images of the nightsky, as they seem to me to be hollow and dead.

Instead of removing stars, I have corrected colours a tiny bit - there were some subtle gradients that I did not like...I recon it will have to go on aluminium!

A stunning image Slawomir. One of your best in my opinion. Presents a pleasing balance of emission lines. They are distinct enough to get an ideal of the nebula characteristics and just as important, look aesthetic.

When I first just looked at the thumbnail it was a "wow" moment, very well captured.

It's a beauty, this was next on my list of images to take, now unnecessary. I really like the colours. Congrats on a fine image.

Cheers

Thats a crackerjack image Slaw.
Bloody hard target in NB (I know, I tried, got over 12hrs data and was still unhappy: gave up...)
Very well done, you have done a stellar job on this, possibly a benchmark for NB on this one.

That looks great... nice to see it in a different color spectrum.. there is not many narrowband versions of the Cat's Paw.

That's a great image. I'll have to have a go at this target in NB too sometime, probably next year.
