I am attaching a jpeg of Comet 74P taken on 4th May 2018

Hopefully not too large and it has the correct designation and that I have sent it to the correct place.

My imaging took place during a single evening ....
Equipment: APM LZOS123/780 f6 refractor and APM Flattener
Camera:     Moravian G2 8300 Mono CCD
Subs on image taken on 4th May 2018:          20 x 100sec CLS subs
Software:   MaximDL and Photoshop
Location:    Garden Observatory 15 miles north of Nottingham.

I ran my processed FITS image through the "Maxim/PinPoint DC3" Astrometrric process ... 
and compared my measurements with an online ephemeris calculator (The Sky 
Live) and found a slight disparity between them as follows;

Maxim/PinPoint Coordinates: 11h 20m 02.96s      +12h 53' 10.7"
The Sky Live Coordinates:       11h 20m 02.2s        +12h 53' 14.3"

They are both very similar .... but am I doing something wrong here?

Regards
Mike Paling
