I would appreciate a critique of my M33 image, which was awarded as IOTD a few days ago. To my eyes, the image is far from excellent, and yet it was my first IOTD. In particular, I noticed several artifacts caused by BlurXT + NoiseXT ("mottling" as Adam Block calls them in his video on the subject), especially in the periphery of the galactic disk. So much so that to get a decent result I had to lower the BXT sharpening to 0.25. Subsequently, I had some difficulty blending L with RGB, in fact I even considered not using luminance at all. In the end, I produced the LRGB with ImageBlend and a blending percentage of 0.6. I treated the HA similarly, blending only a minimal percentage. All this, with an additional difficulty: it was impossible to work on a starless image, since SXT extracted large portions of the galaxy. Therefore, the entire workflow took place with the stars present (and in fact many are bloated). Ultimately, I don't think this is my best image at all, but I'd appreciate your opinion on it.📷 M33![]()
