SH2-132 (Sharpless 132 ) This nebula is a nice one to add to your list and covers about a two degree area. With a larger telescope, you should pick up quite a bit of structure around the brightest area, but the wide field of view also makes for a nice image. I would give this one the time it deserves because the fainter areas have nice detail, but you need enough signal to work with. SH2-132 is also a nice narrowband object, but you need to shoot the SII and OIII channels longer because the Hydrogen Alpha is quite strong. The narrowband really only works well with the brighter part of the nebula on the left side, so maybe a larger telescope is in order to also pick up more structure at the same time.
