Robert, Yes the stability and slew rate are quite critical. The LX-200 classic series are capable of good results (see my pages at http://www.astrospider.com/iss.htm and also http://www.zen32156.zen.co.uk/astrophoto.htm ) Others (e.g. John Locker http://mysite.wanadoo-members.co.uk/satcom_transits/March2005.html) get good results from hand guiding e.g. LX-90 which is not capable of slewing fast enough. I've not seen any images from the current Meade models LX-200GPS etc. but I understand that they have to operate differently using variable slew speed as they can't accept commands as quickly as the classic model.

I'm curious. Is it possible to get useful images of LEO satellites with off-the-shelf equipment? I would imagine that mount stability and slew rate would be the limiting factors..... One of these days I'm planning to upgrade from a 4in Newtonian to a Schmidt-Cassegrain with a motorized mount and would like to know what's necessary to try and image LEO sats.... Thanks, R.
