Can anyone process this m45 to their own style. I'm curious if i can it get more clear data from the nebula surrounding the stars. https://www.mediafire.com/file/srp3cwdzchke818/m45+300mm+gx+169.fits/file |

I think you'd be doing yourself a favor if you stopped at 250mm with that lens. All the youtubers I've seen talking about it (including Nebula Photos and Astrobackyard) say it's not very good with stars at FL above that.

unfortunately, this is the best I can do  - DynamicCrop
- BXT - correct only
- ColorSaturation - desaturated all colors a lot
- ArcsinhStretch
- image rotated
- NoiseXterminator

Here's my take on the data. The data was pretty rough, but got something decent from it. - Crop to remove stacking artifacts around perimeter. - BlurX (default) - ImageSolver - SPCC - EZStretch - Remove purple tint (Invert --> SCNR) - Contrast boost (lum mask, protect highlights) - Saturation boost (lum mask, protect shadows) - Saturation boost (lum mask, protect highlights) - SCNR - NoiseX (0.5)  |

thanks for the attempt. Yeah I agree the stars are too bloated. It was the best i could focus it on for the session.

When imaging objects with dominant bright stars you are better off exposing for the best outcome for the stars and worrying about stretching nebulosity after getting the stars right. It is important to use proper gain for the object, sky conditions and exposure length. The histogram is your friend. 20 minutes in Pixinsight and Photoshop PI: Bxt correct Star reduction in PS Utilities Bxt mild deconvolution Object recognition PS: Mild stretch of starless image Mild color boost Mild curves  PI: Pixel Math to combine stars and starless Seti Astro star Halo reduction Nxt Dynamic crop scott

 Best I could do. Blew out the cores in trying to see how much dust you had in the bg. Needs a bit more data. Steps: Grax Background removal SCNR BXT Halo-B-Gone (didn't really help much) Correct Magenta Stars Script STF Histo Stretch Graxpert Denoise StarXT (I'd normally remove in linear stage, process stars separately and screen back in. didn't plan on using the tool until late) Stretch Starless signal Grax Denoise Screen Stars back in Used star mask from screen-in to boost colors Could have probably got better looking stars by doing star removal from the jump. Then use duplicate image to process the stars more carefully and screen back in Markice S
