Thanks Rex,
Hi Rowland, yes APS-c is perfect. very tempted to debayer a qhy8.
I'm not really looking for widefield but just a bigger FOV. I wonder if a focal reducer will work with the coma corrector.
I'm attempting a mosaic of the rosette tonight using maxim. will see how that goes. if it works, i'll attempt this again from snake valley this new moon.
Cheers
Alistair
