The highest I have pushed mine has been to about 430X via an 11mm Nagler and 2X Televue Barlow. There have been select (Very few) times when I thought it could handle a bit more, times when the Cassini division just jumped out of the EP when looking at Saturn. I think I will gain better value out of something really wide field, but I am just not sure how wide I will be able to go before I just end up with mangled looking things at the edge of the FOV, I don't know how wide you can push the 9.25 before it falls to bits. As per some previous discussion on the site, I wonder about a 24mm Panoptic, which would give me at least the TFOV of the 40mm Celestron Plossl but at higher mag, it would probably obsolete at least two of my current set (The 40mm Celestron and a 25mm TV Plossl) But I would really like to go wider to be able to get wider views of the likes of the Orion nebula, Tarantula ETC.
I am just leery about committing hundreds of dollars to an EP without being able to see how one performs in my own scope (Or someone elses 9.25) first, I took a leap with the 11mm Nagler, but can't afford to do that very often, if I end up with a dud that does not work well in my scope, the frowns from the other side of the bed are likely not to be nice!
