Changed scopes in the dome greg so won't get any more at this scale. That is it

Can't see the nebulosity you guys get with big scopes

Well guided and sharp image. There is some noise in the outer areas but you could remove most of this via some smoothing. Overall though a really nice image.

Sorry guys, edited in some exposure numbers. I pushed it a bit hard trying to get more nebulosity out of it but it just isn't there I'll clean it up a bit before sticking it in the gallery. See ya up there Geoff, I'll try and get out of here on Wednesday I think.

A solid result Robin. Enjoyed the rich saturation. I'm surprised to hear that you mention the data is not there to stretch it hard.

For 15.6hrs of data on a single target using 20min subs, I would be expecting more from the data set? Perhaps data rejection is being too harsh on the subs ripping out the faint structure. Could always try a sum to validate the data is there.

I was expecting more as well Jase and have been playing with it on and off for a while now and tried suming. This is about all I can get out of it, I guess nothing beats aperture
