![]() ![]() This leaves the nebulosity itself more pronounced and easier to see. I find Warpsharp works well on nebulae as it shrinks the size of stars and smooths out the remaining noise if there is any. A lot more sharpening is possible using these same tools if you don't mind the increase in noise or other artifacts. I have gone light on the sharpening settings to have a minimum of artifacts but still see a noticeable improvement in the image. I used VirtualDub and its built in Unsharp Mask and Warpsharp tools in particular. I have put together some image comparisons to try to demonstrate the impact of sharpening tools. Perhaps it could be an option, to choose what scaling to use for the histogram plot? ![]() Is it possible to instead display just the part of the histogram between the white point and black point, or perhaps a little bit on either side of these points? This would in effect zoom in on just the image data that is presently on the screen. Zoom in on histogram: When using the current histogram I sometimes find it difficult to see what is going on with the histogram since the whole 16bits of the image is being displayed, resulting in the image data occupying only a small part of the histogram. Personally I think sharpening would add a great capability for live observing.ģ. I will try to generate some example images when I get home from work to show the impact of applying these two filters. If not set correctly it will also enhance noise, so it works better on a stacked image with low noise. Unsharp mask is a classic detail enhancement tool that can greatly increase contrast in the image. I like it as it tightens up edges and makes stars less bloated, and it reduces the visibility of noise. The warpsharp algorithm is out there in the opensource world. I especially like "warpsharp" and "unsharp mask". In the past I have passed my live feed through VirtualDub using its screen capture tool, then applied sharpening filters in VD. Sharpening tools: I can recall asking about this in the past (I just don't remember who I asked!) but am yet to see it implemented in most EAA software. As an example the white/grey/black set point sliders on the histogram in the Infinity software works very nicely.Ģ. ![]() On really dim objects it would be nice to push the gamma even more than what the presets allow for. Although the presets work well, I still miss being able to adjust gamma (or "grey point") manually. User defined gamma: Very early versions of LodestarLive had an extra slider to adjust gamma, but that has since been replaced by the three histogram scaling presets (linear, arcsinh & x^0.25). I wonder if it is okay to make requests wrt software features? I have a few ideas but don't know how major an effort they would be to implement.ġ. ![]()
