Hi,
Nice images, looks like the camera has very high QE.

Very nice! Thanks for sharing. Are they taken locally or overseas?

Nice collection of pictures. What is the setting on the camera (e.g. exposure time etc) ? Keep them coming.

All shots taken at Jurong West.
Most subs taken at 4,5 or 10 minutes.
Ring nebula i remember was 3x4minutes.
Andromeda was 10x10 minutes.

That's quite a bagful of splendid imagery, ChaosKnight! The STi is one fine autoguider. Great sensitivity, regularity of low chip noise, clean electronics, and a moderately wide FOV. Have you tried on the planets? Should be great for them too, with the high fps and sensitivity plus fast downloads...

Re: Experiment using autoguider for deep sky.
Thanks for the input.
I still have issues getting flatfields. Apparently the C6 displays significant vignetting when brought down to ~F/3, even for the small chip. Currently using an acrylic sheet, but it doesn't work well. I know there are electroluminescient panels, but i'm looking for a reliable, simple solution without need for power.
