Ic 4628

[MarkInSpace (Mark)]

Finally had some clear skies against all odds last night and I managed to schedule in IC4628.
I've been wanting to use dithering, so this is a first attempt. I ran APT and PHD2 with dithering set for every frame at level 5.
Processed with PI and PS.

Looks like it's working for you. Good stellar profiles and SNR.
Remaining field aberrations are mostly mechanical tilt and a tad of coma but that's a 9/10 otherwise as far as data goes. You look at the starfield and you notice straight away it's a good capture.

yep, thats a ripper, especially for 90mins!!

Thanks Marc. The dithering was at your suggestion, I think it worked well.
I’ve installed a tilter on the camera body, but haven’t tried setting it up yet.
Waiting for a wave of brave bravado, then I will attempt!!

Ahhh - this is the Prawn nebula - I had tried to image this a while ago - before I was plate solving - and never captured it - thanks for the info!

Most excellent Prawn.
