Nice clear night for a few hours in the back garden 
Stock Canon 5D MkIV and William Optics Zenithstar 61 with flattener on a iOptron SkyGuider Pro guided in PHD2 with ZWO ASI120mm and 30mm f/4 guidescope.

30 x 4 minute exposures of the Deneb region, 20 darks/flats and 50 bias frames captured with APT. Calibrated and integrated in Astro Pixel Processor then finished in PixInsight and PS.

Full frame image with 100px crop on the borders to remove the dithering artifacts.

Center (RA, Dec): (312.884, 44.134)
Center (RA, hms): 20h 51m 32.201s
Center (Dec, dms): +44° 08' 03.276"
Size: 5.56 x 3.6 deg
Radius: 3.311 deg
Pixel scale: 9.77 arcsec/pixel 3.07 arcsec/pixel
Orientation: Up is 341 degrees E of N

Nice image Kev, I've got a WOZ61 that doesn't see much use must try to set it up on the Star Adventurer while the other rig is imaging.

Curious about the image scale 9.77, I use a Canon 60Da on mine which I think from memory gives around 2.5 as/pixel presumably the 5D has bigger pixels but your figure looks a bit high ?

I saw that as well Dave, CCDCalc reports the scale as 3.07arc-sec/pixel which I used for my dithering calculation (6720px wide sensor and 5.36 micron pixel size).

Okay I know why, I resized the full frame down to 2048 pixels wide for Nova to work on  I've corrected the top post
