Roger,
A miraculous effort indeed. I find it inspiring when one embarks on such challenges like this. Really is a lot of work and takes considerable dedication. There are a couple of things I'm not certain of. Within the PDF documents, many images are repeated NGC1934 through to NCG2117. While I don't have any problem with the repeated images as I gathered that there are multiple targets in the single frame, but I really don't know what target its referring to. Perhaps you need to place cross-hairs on those individual targets in each frame to give the viewer and indication of what NGC object is being referenced. I'm also not certain if your choice of format being PDF is ideal. Clearly, as you progress with acquiring more and more images, the ugliness of data management will emerge. You may wish to consider piping this into a mySQL database with a simple web front end. The SQL database will certainly give you the structure and flexibility you desire. You could then give the viewer the opportunity to search for different criteria, i.e. show me all NGC objects in the constellation Hydra or show me objects that are larger the 1.2 x 1.0 arcsecs. It is possible to embed the binary images into the SQL database itself to make the solution clean. It could get rather funky depending how far you want to take it. I look forward to seeing more of your own digital sky survey...wow...the possibilities...you could also start on the IC objects in parallel. This is where a SQL database could become handy i.e. when a single target has multiple designations. Food for thought anyway. Well done and keep it going.
