The ZWO FF series is a potential fit for your astro-photography needs.  

The ZWO FF65 APO is a flat field astrograph that can be used visually as well.  Its design negates the need to calculate the back focus distance from the flattener while attaching all your imaging gear.  You should be able to connect a reasonable amount of equipment and start imaging.  This should help with the frustration of getting everything just right and simply let you enjoy your imaging session.

You can use a variety of diagonals for visual observation should you choose to look through your telescope and not just image through your telescope.

The telescope is fairly compact and lightweight.  The ZWO FF65 is a hair under 13" long and weighs in at 6 pounds with rings and dovetail. The 65mm aperture scope uses a dual ED quintuplet optical system to help achieve its flat field.  It is fairly fast at f/6.4, but can be made faster with optional .75x Reducer further reducing the speed as well as the 416mm native focal length to f/4.8 and 312mm.

The ZWO FF65 can support a 44mm image circle allowing it to be used with full frame cameras.  The 2.5" focuser has a built in camera rotator and  finder shoe for Vixen style finder brackets.  The telescope comes with M68, M54m and M48 Camera adapters and the M48 is threaded for filter.
