diagnostic request

[alacant]

Hi everyone. Here's a full size 700d cr2 which I converted to jpg. The latter looks identical to the former. Can anyone diagnose what's wrong, if anything? TIA.

Is that the rosette?

How long are the exposures etc, looks fine to me.. stars are nice and round in the centre with a bit of field curvature on the edges..id guess it's taken with a frac, are you using a reducer with it?

Hi and thanks for the input. It's either m67 or m48; the only object with a reasonable number stars I could find away from the moon last night. It was around a minute. I had to set the ISO low to prevent a pink mush wiping out the stars. No reducer as far as I know.

Looks ok to me. Very good. Stars look sharp.
