Hello from Austria!

This is my first light with my brand new Sigma 105mm f1.4 A 🙂

NGC 7000 105mm

The lights were stacked and calibrated in APP. The final processing was done in Starnet++,Topaz Denoise and Photoshop.

Critical feedback is welcome 🙂

Beautiful! I would be a little careful with Topaz though, isn't that the AI sharpening tool? It's not trained on astonomy pictures so might introduce artefacts sometimes.

@vincent-mod

Thx 🙂 

This is the first project where I tried Topaz Denoise. Although the program reduces the noise, it always sharpens the image.

Let's see if I will use it again in the future 🙂

Here is the starless picture:

Really nice, just wanted to mention it as it can introduce artefacts, it doesn't do that always. 🙂

Beautiful!

I assume the L-pro is a clip-in filter (from a jealous Canon 5D MKIV user - they don't fit my camera  🙄 )

@stephent

 

Thx Stephen 🙂

 

I used a clip-in filter for Canon APSC cameras. I think the Canon 5D Mark IV has a special shutter where the filter would block the mechanism if triggered...!?

@vincent-mod Topaz has a sharpening tool and a denier, the denoiser works exceedingly well and is the best in class.  I have been using it in Astro and general photography since the Ai version was launched.  The sharpener is not as versatile.

@skanker you can control the sharpening independently of denoising on Topaz Denoise, as well as detail recovery.

I know ... I believe that despite the sharpness value is zero, a certain sharpening takes place!?
