I’ve used a small amount of deconvolution to try to sharpen up the dust lanes in the galaxy but I’ve never been happy with the way deconvolution appears on OSC data, even with a bayer drizzle which is supposed to remove the issues from interpolation.

In the future I’d like to see if I can run more of the 12 hours while still keeping a sharp image but I’m not sure how much more of the 1.8-2” or 2”+ frames I can add before the SNR increase from more data vs SNR from lower FWHM makes it worse overall.
This particular stack is at 1.71” in the centre of the frame so it’s come up pretty sharp so far. |
Hi Colin,
That is a lovely sharp image of Centaurus A, and taken from Bortle 6 skies, it doesn't get much better than that.
