Critique Style Requested: Standard

The photographer is looking for generalized feedback about the aesthetic and technical qualities of their image.

Description

From the night of November 7 – one of three nights I was able to get it and none were good. Also neglected to rotate the camera to put it in the correct orientation. I was just thinking to get as much of the tail as I could. So much of the processing in PixInsight needs numerical input to maximize things, and as I progress through steps I often find a previous one was less than ideal but it wasn’t obvious until I did other things. Unlike PS, there are no layers to modify. You just go back a rework from the problematic point. The lighter blobs in the sky should not be there and I lost the bluegreen in the head. Darker clearer skies and more time on it would be better. I’ll do a RP when I have time to try to find the problems.

Specific Feedback

All comments welcome!

Technical Details

50 30-sec exposures tracked with my astro rig (refractor telescope and astro camera), processed in PixInsight. (Trust me, you don’t want the details…)

Boy I wish I can take photographs like this Diane. The only comment I would add is to give more space on the right side and if possible… slightly add some saturation to the image to enhance some of the colors. I think you want to be subtle with the saturation. Beautiful photograph!

A truly beautiful image. One that’s well and truly out of my skill set.

Diane,

Very nice capture and processing. You got some great detail and color in the Ion Tail. Nice noise free image.

Thanks, @stephen_rauch, @glennie and @Youssef_Ismail! This isn’t what it should be and I need to spend more time sorting out some arcane details of PixInsight processing. I also need to process the other 2 nights – all three had issues, but I might hack a little further through the jungle of processing by tackling all three.

@stephen_rauch, yes, saturation could be increased, but when I did other issues became more apparent. Eventually I’ll come up with the best method and be able to get whatever I can of the three. This one can be improved, but not after the fact.
