Description

NGC 1491, the Fossil Footprint Nebula, in hydrogen-alpha and oxygen. Captured over two nights using 6 minute subs with an ASI294MM Pro and Esprit 150 with a Riccardi reducer (Ha=80; Oiii=70 subs). Good weather made the image capture fairly easy, but subsequent processing was somewhat challenging due to gradients and the relative weakness of the Oiii signal. I experimented with the Topaz Labs software after initial stacking and processing with APP and Star Tools. I found the Topaz Denoise worked well except for stars which were easily degraded by artifacts. Using the Topaz Gigapixel software I was able to upscale the image and recover round stars.
