I finally did it - created my first ever mosaic! Followed the instructions from Mabula, dipping into a couple of other posts about combining the channels in rgb combine. I hope you like it! This ended up as a six panel mosaic, with each panel comprised of 54 x 240s lights taken with an Altair Hypercam 183C fancooled, through an Altair ED80 triplet apo. I used a quadband filter, then split each of the panels using the 'extract Ha' and 'extract OIII' algorithms before re-combining the mosaics using rgb combine. Some final tweaks were done in Photoshop, but the great majority of the post-processing was done in APP.
