With slight image enhancement (and clipping) nova.astrometry.net solved the
image.
Image scale, image with identified stars, and link to fits file available
from
http://nova.astrometry.net/status/2023277

My reduction from the .fits, using SAOimage DS9 gives
RA 09:51:27 Dec -16:47:22
RA 09:56:38 Dec -16:55:35

Some EXIF data from the image:
Filename - Leo 20180420 IMG_2244.JPG
Model - Canon EOS 400D DIGITAL
ExposureTime - 3 seconds
FNumber - 5.60

DateTimeDigitized - 2018:04:20 21:41:21
FocalLength - 55 mm
