Hello, 

I've been working on this object for a couple of nights to reach a total integration time of 18.5 hours. Two-panel SHO data were processed and combined in APP. Noise reduction and color enhancement were applied in PI and Lr. My gears are: QHY163m, Takahashi TSA120, Astro-physics Mach1, Antlia 3.5nm NB filters. Here is the link for acquisition information and higher image resolution https://astrob.in/fbg3mq/B/.

Clear skies,

Kijja

That looks very nice, difficult to get the background corrected I can image with all the nebulosity. 🙂 Did you add some sort of smoothing to the nebula?

You hit to the points again! Thank you for the issues of correct background and de-noise. To be honest, I am not sure for what should be the correct background of this nebula. I just use Ha for Luminance, everything outside Ha was considered as background. I also applied de-noise from Nik software to the final touch. This is probably too much. What is your ideas for improving this image?

Oh, it was not a criticism, I meant to say that I find the result good with so many nebulosity. That's always difficult to get nice. 🙂

So I think that looks fine, I would maybe not use the denoise option as I think it removes detail in the nebula.

Don't worry, I always want to listen to your constructive comments. I agree with your comment on too much denoise. More lights were acquired to improve SNR so that the need for noise reduction was lessen. Here is the link to my new image https://astrob.in/fbg3mq/C/
