Hi Brains trust

Tonight I want to go for broke. Have my scope aligned, PHD is good.

This morning I took 20 of 30s lights (darks etc) for integration time of 10 minutes (see attached image).

Still not enough detail.

My question is, what integration time do should I go for?

In short, the more the better :)
Think of an hour as a minimum.

Thanks and sorry to bug you all so much.
I will be out of your hair soon enough :-)

So tomorrow I can see Orion from 3AM to 5AM (twilight starts) so that gives me 2 hours.
So my plan is 120 exposures at 1 minute each.

Is that OK?

What camera do you use?
I had good results with Canon 60D, 16x 1 min.

But yes, as Colin says, more the better.

Also, pay attention to focus... bahtinov mask may be very helpful ;)
And dark(er) site of course.

yep, lots :) I'm waiting for orion to be up at a sensible hour so i can add to last years data, and the year before that... :)

it depends really also on your processing and how well you can push signal and reduce noise. there are ways and means, lots of practice, take notes, build a workflow that works for you to get a result.you may be clipping blacks too much, I think there is more in your data for you to pull out of the darkness.
