One question, two answers
If you're intersted in scanning other formats with tis scanner, there is a trick (if you use vuescan)by which you can scan xpan frames(24 * 65 mm). In short you scan first one half an de a bit and then the other side. If you're interseted, I can give you a link to a newsgroup where it was described.

If you want to make a panorama using ordinary 35mm photos, I have indeed found Panorama Factory the best option if the images have to be warped etc.
If you want just a stitch in which no account is taken of the focal length of the lens used, you could try Photoshop Elements (version 2 is to be released in a month or so)

: As we can not use this scanner to scan other formats than 35 mm, I have tried to stich 35 mm pictures together.
: I tried Ulead Cool 360 ( a toy) and The Panorama Factory software.The later one really works and after a color adjustment in Photoshop, I got a great panorama.
: Any comments on panoramas created in the digital darkroom are very much appreciated.
