this is1h52min worth of imaging of NGC5128 with a partial moon. entirely processed in pixinsight, stacked in Deepsky stacker. mixture of 5, 10, 15, 30, 40, 60 second shots with a gain of 40 with the ASI071 through a 11" RASA. unguided on a titan mount from the doghouse observatory

two versions, need more data

Looks OK David, the RASA sure gives you a very wide field of view.
Cheers

Would be even wider if I bought the asi094 which is double the size of this but I thought better of it. Need to learn the toy I have now. The greatest exposure was 60sec In the stack. I think for memory there were 30 1sec shots, 30 5 sec shots, 30 15 sec shots, 30 30sec shots and the rest were 60sec

It you had the chance to get this scope into dark skies for a mega data runs this would pick up a lot of cirrus. You might even get the entire jet too David. The potential here is great.

i doubt i would ever get the jet but i think 5 hours on this with 5min subs with this scope would get something

You could always do with a backup camera David.

Great shot mate, this new scope is areal winner.
Well done my friend.

Looks good David.

I reckon you'd need to push 15min subs or more to get the jet maybe in Ha. I tried to go deep with the hyperstar from home on the helix and you're still limited by your skyglow unfortunately.

The backup camera is the fli 8300 osc I already have

Yeah but do you have a backup camera for that one?

That's a lot more widefield than I was expecting. Looking promising for a deep run.
