![]() Now, I know it's better to 'get it right in camera', but if you come back from a trip to a dark site and by some terrible error everything is OOF or trailed, this gives some hope. Warning it's very slow, maybe 3 minutes on my computer to process a large file. because of that, I like 'stabilize' most. It's odd that 'sharpen' produces a lot of blue stars. I used the other two modes at their default of 50%, but stabilize at 100 % because in every case I looked at, 50% seemed like weak tea. The Topaz tools are incidentally tools that work with astro images and in some cases work well. Stabilize also improves images that don't have trailing:Ĭlockwise from upper left: 'focus', 'sharpen', unprocessed, 'stabilize'. The greater magnification shows the artifacts in the middle (simple stabilize at 100 power), and the improvement in star shapes with some Gausssian broadening. But, as the names suggest, they each have a different focus. Both Sharpen AI and DeNoise AI offer image sharpening and noise reduction. But it’s worth taking advantage of the free trial. You can buy them individually or as a set for a one-off fee. ![]() But looking closely, there were some artifacts at the base of the bright stars, so I applied 0.5 pixel Gaussian broadening to suppress them and got the RHS image. Topaz Labs has a suite of three main programsSharpen AI, DeNoise AI, and Gigapixel AI. I ran this mode with the power at 100% and got the middle view. 'Stabilize' is the one to use for trailed stars. So what can be done? Topaz Sharpen AI (nfi) has 3 modes- sharpen, stabilize, and focus. I was testing how long I could expose (I bumped the tripod, and 30 sec subs were fine, but I wondered if I could extend that.0 The image LHS is 3 minutes (200%), and the trailing make it look like 1 minute is about the limit. Someone posted on another forum about this product, so I thought I'd try it for astro, especially for cases where the stars are trailed a bit.
