first time shooting and editing a globularI and was hoping to get some feedback on it. A few things that catch my eye was it might be a bit sort and it seems to bee lacking color. Not sure if the softness im seeing is due to seeing (it wasnt that great), collimation slightly off, focus slightly off, or any combination of those! I use NINA’s autofocus routine and get a pretty decent u shaped curve. Withregards to the color, not sure on that. Im pretty new pixinsight user, third image ive edited with it, maybe more curves transformation with saturation is needed? I may have over done the BlurXterminator use. I left the core a little hotter as i think i like it that way. this is only about 17 minutes of data so maybe a full hour would produce more color? equipment, data collection, and processing notes: lights:350@3s darks/flats/dark flats b4 skies; backyard c9.25 with celestron reducer uv/ir cut filter celestron oag zwo asi 174mm guide cam zwo asi 294mc pro EQ6r Pro NINA,PHD2 PROCESSING NOTES used pixinsight for image calibration, integration, and processing WBPP Dynamic Crop Dynamic Bachground Extraction SPCC BlurXterminator NoiseXterminator Histogram Transformation HDRTransformation script Curves Transformation (contrast and saturation) final color balance in PS Adam Blocks tutorials Any comments/suggestions would be appreciated! thanks M13 |

OK... I'll temper my critique on this not even being a 20 minute integration
Here's the same area (roughly) from my version of M13: Forgive the egg-shaped stars on mine... tracking/guiding issues with my setup. My image scale was a bit finer than yours at 0.46"/px vs your 0.72"/px. What I wanted to emphasize is how on your image structure has been blurred together, creating rather interesting artifacts. Most of this is just me pixel peeping and nitpicking. Taking the image as a whole I think it's pretty darn nice for less than 20 minutes of time on target (mine is 4.5 hours by comparison). |
