Each time the crescent Moon comes around, I'm tempted with a challenge of trying to capture both the night and day sides of the Moon in one exposure, without any HDR blends or masks. It turns out that one of the trickiest aspects of this is simply one of logistics. I don't have a good view of the Moon once it drops below about 25 degrees, and for the narrow crescents, this means I lose sight of it before the sky gets totally dark. Tonight, for example, the result would have been much better if I could have imaged about 30 minutes later than I did, but it was not possible. So this will have to do. Some considerable downsizing is required so that the image becomes presentable, but I do like that details on both the night and day sides are visible, without any pixel saturation. To see the faint details on the night side, you may have to dim the lights and crank your monitor, but they are there. The camera has no trouble capturing the necessary dynamic range in one exposure, at least at this phase, contrary to what you may read elsewhere about this being impossible. This is also only an 8 bit recording, with 1500 frames stacked. Exposure was 18ms with 44% gain on the ASI183mm, using a 742nm IR filter, good for an 81% histogram fill. Scope was a 6" TPO Newtonian, imaged at f/6, 916mm focal length, with a Baader MPCC Mark III coma corrector. The image is downsized and cropped, but the background is completely intact (no background subtraction).
