Hi all, I plan to invest in a compact astrograph to gain a wider FOV. At the moment I'm using a William Optics FLT98 with it's dedicated field flattener, the AFR-IV which gives me F5.
It'a a lot of weight hanging off the focuser with my SBIG 8300 attached & whilst I'm relatively pleased with the results I like the idea of a flatfield Petsval refractor design without the complication of spacers etc. & less flexure.
These are the two I'm interested in:
The Sky Rover can be had online for Circa $1200

The Sharpstar will be available in Sydney shortly for $1100 + shipping

I'm aware Casstony has the 61EDPH which seems very capable, (feel free to comment Tony
). I must admit I'm drawn towards the Sky Rover though with it's slight aperture advantage.
A flat field & good colour correction are important to me. Any thoughts?. Thank in advance.
Tony
