I would like to second Jose's suggestion concerning flat frame application. For those of us who cannot afford $5,000 OTA's with 3 inch and larger focusers, and who love doing outreach, cameras such as the Horizon and those with even larger chips are only practical if "on the fly" flat application is possible.
It is for this reason that I may possibly trade my Horizon camera for a ZWO ASI294, since the Sharpcap application has recently allowed for live calibration frame usage.
Thank you
