Any particular image capture program you'd recommend?
I have RegiStax, but heard Sharpcap is worth trying.

yep, that's the ideal FNo for 5.6micron pixels. Powermates and Barlows are both fine for this task as Ken says.
The only downside is that the SSAG is pretty noisy compared to more modern cameras - you will need to use darks and flats with it (no major penalty) to remove fixed pattern noise and it will also lack a bit of sensitivity on dim targets like Saturn - should be good on Mars and the moon though.
Firecapture is the capture program I prefer - not sure if it supports the SSAG though.
