Matt, My ST10 was the XEI model, no self guiding chip.. However my ST-9E was self guiding, and I can tell you now, I can not wait to go back to a self guided SBIG... If you want a setup that only requires one scope, and you want it to be easy to use, Go get yourself an SBIG... My ST-9E was capable of self guiding through a 13nm Ha filter without a worry, I did 2 second guide exposures with the guide chip at bin 2x2 and never had a single trouble finding a guide star... From what I understand, the newer ST cameras have a much more sensitive guide chip than my old ST-9E, so this could only mean that provided your Ha filter is not too narrow (read : 3~4.5nm) you should be able to self guide without an issue.
Definitely if you're looking to do s/nova searches with short exposures, the ST10XME is the tool for the job... It will excel in that field, whilst still offering great resolution and field of view for "pretty picture" photography. The ST10XME also has one of the most sensitive sensors available today with a peak QE of 95%, you really can't go wrong...
Just for reference, Im looking to get another ST10 in the next short while, and at the moment with the STX series set to be released very soon, the prices are becoming very reasonable.. Optcorp in USA have a sale going, buy the ST10XME for $4995USD and get a CFW9 filterwheel for just $390 more.. Can not go wrong.
Yes sir... I like SBIG self guiding. I like it a lot!
