Hi JohnH,
The ST-5 would be much more senistive than the MEADE LPI, (will do Mag. 14 star in 1 Sec.) It is a cooled chip Camera, and can take the chip temp. down some 50 Deg. below ambient, It will operate directly into the RJ-11 CCD port of any MEADE , Celestron Ultima, or Losmandy scope, also others (it was designed for this purpose) in addition to Imaging, I can send you more details (copied from handbook) if required (your E-Mail address required) but I would suggest you look at
http://www.company7.com/sbig/products/st5c.html , which gives all the Specs. on this camera.
regards...........Jim
