This ones a bit rough and ready. The data was not that good.  |

Well done getting these. At 90 MLY away they are very tiny objects to image. The foreground stars are only 30 MLY away that is why they appear so large in comparison. Great shot.

I had another go in Startools using the same DSS image. I think I have produced a much better result this time around. The layer noise reduction is a fantastic tool!  |

I will have another go at imaging this one using much longer exposures to try and dig out some more detail and improve the S/N.
I need to pay more attention to the histogram.also the colours are not quite right. I read somewhere that it is also a good idea to calibrate the monitor you are using so you don't see faulse colours when processing the image.. I did not see so much purple hue on my laptop.i will check the calibration!!

Perhaps a lot of the purple is associated with the stretching and being so distant some redshift also.
