Thanks Trevor. I'd like to do a mosaic once I have my home observatory up as it would take a few weeks probably. FSQ106 with its reducer and the 16803 would be the choice or perhaps even AP140 with its reducer would be even better.

Exquisite. Just the right focal length.

Thanks for that. That is the idea the image evokes for sure.

Its the O111 that has all the detail. It seems a lot of these objects are best in O111 - like Thors Helmet.

Thanks Fred. I'm actually redoing it using median combine rather than sum combine which leaves too much rubbish in the shot. These sensitive chips come at a cost of lots of little cosmic rays that you don't see in STL11 cameras. So median combine is my only choice for now unless there is some other way of cleaning them up. There is very little difference between median combine and sum but on this one I thought I saw a slight improvement in detail from sum over median but the cost is the artifacts which takes a lot of healing tool.

Red (SII?) seems to have left some star artifacts. As an alternative view, ive clipped the background to isolate the cloud structure, sorry about the low res.
I fixed that now. Got rid of the red. Not sure where that comes from. I suppose S11 must see some stars that Ha and O111 don't?
