The instructions that come with the 'cheapie' camera are appalling. So the extra work comes from determining for yourself what the appropriate settings are. The makers of Revolution Imager seem to have determined these settings, and MAY have configured the camera for astro use. There is no info directly mentioning this, only alluding. As I have no experience with the Revolution Imager, I cannot speak for it. I'm not being dismissive, just cautious. I do like how they've made the TFT screen capable of being mounted onto the scope using a tripod ball attachment
Sourcing the bits and pieces to make the 'cheapie' work is easy and inexpensive. But the trade off is determining the 'instructions' for yourself.
