Dave, Well, that's way beyond where I ever expect to get to! I am more interested in EAA and saving good images as photos than getting deeply into actual astrophotography. One of the main lessons I think you are trying to convey to me is to really pay attention to the histogram to get the black/whit...

I was referring to your M27 image here: https://forums.sharpcap.co.uk/viewtopic.php?t=297&sid=2a146e59dcc4c8ae776a8ef6b6b109cb I didn't realize SharpCap has a reticule. I will have to start using that. For alignment, I start with using the GoTo function for the aligned scope, then center the obj...

Wow. I don't know how to express my gratitude. Thank you so much. I had just started to play with this image in GIMP as well, but was only using the brightness/contrast tool and curves and was not satisfied with my result. I had just resigned myself to studying the GIMP user manual to learn how to u...

Here are a couple of other images of M27 that I saved the same night using different black level and gamma settings. I am having trouble choosing which one is "best." I tend to like the image with the darker background, but then I'm not sure it shows as much of the fainter parts of the neb...

I am saving the stack (not an individual frame) as a png file. So it should correspond with the histogram. Where i am confused is that the camera control brightness affects the black level and gamma I choose in the histogram, yet the camera control brightness is not included in the saved png. So I m...

Thanks Dave. And thanks for the link to the histogram page. I had read all that beforehand, but promptly forgot most of it while trying to capture the image! I will have to slow down and develop a procedure to take advantage of all the options. I think it will be mostly a matter of just doing it, ex...

Thanks for the reply Robin. So Live Stacking immediately stretches the histogram? I must have missed that in the manual. I saw where it explains how a user can use the histogram tool to apply a stretch. I didn't notice that occurring in the tutorial videos I watched or in pictures I've seen posted w...

I am using a Celestron Evolution 8 with the Revolution Imager 2 camera. When previewing an image in SharpCap of a DSO (e.g., M57), the image is as expected - a dark (basically black) background with a faint image of the object. As soon as I start Live Stacking however, I get a bright, greenish backg...
