Quote:Hi Jeremy,I don't know of list of cataloged objects in other galaxies, but if you go to http://www.ngcicproject.org/dss/dss_messier.asp you can find images of M31, M33 and M101 with their NGC and IC objects labeled. It's nowhere near complete but it's a start.Although it would take more effort, you can use the Aladin Sky Atlas, http://aladin.u-strasbg.fr/ to locate tons of objects in other galaxies. You'll find all sorts of objects, most of which there's no hope to see visually, but this is the most exhaustive source I know of. You'll certainly gain an appreciation of how many discrete objects have been identified in the closest galaxies.
Quote:Generally one has to search the primary scientific literature for specific galaxies. It is not easy but at least most articles are now freely available online.The printed books I consult most often are1) Atlas of the Messier Objects by Stoyan and others (Cambridge, recent). It has photographic charts for many Messier galaxies with objects labeled that are most likely to be accessible to visual observers. In general the book follows good practice as far as citations, but it seems that there are omissions and in some cases it requires some work to identify the objects mentioned with the professional literature sources.2) An Atlas of Local Group Galaxies by Hodge and others (Kluwer, recent). It is a multi-band photographic atlas and catalog of objects within the Local Group galaxies, with the exception of M31 and the Magellanic Clouds. It is so detailed that it is not convenient to use at the telescope as the first resort, but it is invaluable when you target objects beyond the most prominent in busy fields. Watch out for a few errors in catalog tables, e.g. cross-identification between primary sources. But it is probably safe to say that there is no printed book of comparable scope and depth.3) Atlas of the Andromeda Galaxy by Hodge (long out of print). This one covers M31 in the same style. Some information is out of date. Generally it is good for the visual observer to restrict himself to objects discovered by the time of this book's printing, so the incompleteness is not the problem. The problem may be objects whose extragalactic nature has since been refuted. There is a kind of electronic version of this book on NED, although it is even more difficult to use than the printed book.I also consult the atlases created by Hodge and co-authors for the Magellanic Clouds. Long out of print, these are boxes of unbound photographic charts in B, V, and H-alpha, accompanied by slim catalog books. Recently I have also consulted Alvin Huey's PDF guide to observing the Local Group (faint-fuzzies.com).

You planning on going outside the galaxy? With your 16" you should be able to get many of these. I did with my 12.5 although it took my 20" to complete most of the extra galactic GCs. Bill
