A couple of images of M51 taken last week in Pembrokeshire. Celestron C8 SCT with Antares f6.3 focal reducer, Canon 50D, ISO 2500, 14 90 second exposures unguided on an EQ-5, darks and flats.

Very nice images. Did you try a different processing technique between the two or are they both 14 X 90 sec images?

Thanks for your comments. I used DSS on both, but am having real trouble with the settings, so tried a couple of times and got two different outputs! If only I could master DSS I would be happy :)

Hi CThody, Those are really impressive shots, I have the same setup and didn't think you could get as good as those with the mount we have especially unguided. I'm gonna have to give it a go!
