I thought I'd try sticking a couple of frames of the LMC together using pixinsight. The CLS filter must be at a slight angle in the Tak's T-adapter as there are some very strange colour gradients in all the images I got with this in place, but the pixinsight DBE tool does seem to do a good job of removing them.
I need to go out and get some more data and construct a more carefully planned mosaic, but I think this might work out for my eventual plan of a wall-sized print of the LMC.
Each panel is only half an hour's worth 3 x 10 mins @ iso2000. I had to resize this image by 50% to get it onto astrobin again, there's a limit to how many pixels they can manage.
hardware = D800 + Tak FSQ106 + G11.
