affinity photo Comparing Affinity Photo vs Astro Pixel Processor

[Didge]

Hi,

I've been experimenting with Affinity Photo over the last few days to see how well it performs vs Astro Pixel Processor
for aligning astro images and applying levels and curve adjustments.

I stacked 95x10s subs of the Globular Cluster NGC-6723, which represents a tiny portion of an original image of the region around Corona Australis (which you can see on my Astrobin page here).

Image (a) is an unaligned stack, to show the range of mis-alignment;

Image (b) is the same stack aligned and adjusted using APP;

Image (c)  is the same stack aligned and adjusted using Affinity Photo.

The levels and colour balance are slightly different, but the alignment done by Affinity Photo is every bit as good as that done by APP.

I find Affinity Photo much easier to use than APP, and much more versatile for other image editing tasks.

For me, Affinity Photo replaces both APP and Photoshop, which IMHO makes it excellent value.

The celestial bodies in the Affinity Photo version are distinguishable the best from the 3 renderings.

Hi VectorWhiz,

To be fair to APP, I probably spent more time adjusting image (c), but that was really easy to do in Affinity Photo.

The image has a slightly darker background, but IMHO the stars are perfectly aligned, and also a bit sharper.
