Yes Andy, as mentioned I had a late shift so haven't been able to do the full comparison yet. How long are your subs? Thats important, as my friend is currently doing the same length as me, 15 mins. If you could do some 15's that's give even better data. Thanks for sending the files too!
I will produce some 'blinked' and star aligned comparisons and assuming that the comparisons favour your 683, I tell you I'm gonna send the comparisons to QSI themselves, as we need to help them out. I hear their sales are suffering due to the newer cams. Very few ppl in the world are imaging at 15 mins, so I may be exposing the cam's limitations. I've imaged from 3secs to 300 to 600 as well as 900. The cam is not magic, it needs longer subs to match it with you deep imagers.
Colin, good idea, might try some new subs soon. In fact tonight!
Yes I tried fixing stars in Startools, but alas that repair function wrecks my nice diffraction spikes and more importantly does damage some neb detail.
I know what you are saying re collimation and neb detail, but the raw images do show some pretty nice detail. But the OIII for example, there's massive loss of signal in mine compared to Andy's, just white blobs compared to lovely whispy bits (near the chooks bum, as Mike scientifically noted!). That can't be caused by slightly off collimation.
