A solid image Rick. I can see where Greg is coming from but the result does accentuate the main features. Its easy to fall into the trap of raising the blackpoint too high to increase contrast of the dark nebulae. A trick I sometimes use is to have two layers of the same image in photoshop. Stretch the data so they are similar in illumination. On the bottom layer (blend: normal mode), establish an S curve predominatly focused on constrast between the shadows and midtones. Keep the highlights flat or just give them a little bit of a push but not much. On the top layer (blend: lighten mode). This layer counteracts any clipping of the shadows assuming your bottom layer contrast is quite steep. I then adjust the opacity slider to taste. The muliply blend mode is also good for providing more contrast as is the shadow/highlights tool if not overly done. Of course, the above is all Photoshop related. I notice you are using PixInsight. In this case, I can't really help too much. I'm still learning many of its features myself. HDRWavelets are good and probably the only real function I know enough about to understand what it is doing to the data. Experimenting is the key. Keep at it. Looking forward to more in the future.
