star blooms

[sparq]

Can anyone suggest a way to remove star blooms that doesn't involve camera rotation and HDR?  Thnx.

The only way I can think of is clone stamp, or find another image from another imaging train with a similar resolution and then substitute those pixels in.

Hi,

There is a script call "StarHaloReducer" that might work.  If it is only a couple of big stars, then create a range or star mask that covers the halo(s) and apply and invert the mask.  Now use CurvesTransformation and if the halo is blue, then reduce the blue line until the halo disappears.

I use MaximDL.  It requires saving the images as fits, running Maxim, and resaving as xisf.  Cumbersome but effective.  I use BatchFormatConversion to convert the formats.  I do this after calibration and running CosmeticCorrection and just before alignment.
