I've been using TPoint modes of 150+ points and PEC from day one, both are trained well. If I do actually have a guide star available 600s exposures never have a problem.
I guess it's a combination of in the past wanting quick results waiting a short time for the first exposure), that about 50% the time there is no guide star so it's easier to just not rely on one ever, and that until this discussion (including some PM's from people) I haven't realised the significance of the read noise of the ST8 compared to the signal.
Better crack that whip and get me back to 600s+ exposures. I used to do 600s & 1200s with my LX200 classic for crying out loud.
I love it ! ...now my new desktop image. There is something about a great galaxy group image that just draws me in.
That's great Ian. I have a few galaxy group images and I agree they are very interesting. Thanks to Mike Sidonio for his image of this area that inspired me to take an image of it.
Greg time to mega up mate. Good colour, great detail but the only thing letting this image down is the background noise and colour noise. Otherwise this is a lovely image.

Thanks Paul. I think its moved on now so next year it'll be on my list.
it's a pretty cool cluster huh? 
Not NGC1232 though hehe. I can look through the ESO catalogue too!
