Very nice ,I must admit that it isn't so obvious that the stars are elongated to the corners.
A FF wil improve the picture but to what extend I am not sure.
Myself just ordered a FF IV from WO to connect to my new FLT 98 (cant get focus now with Cooled Canon Eos 40DA)
I am quite new to the digital revolution so probably will ask for advice many times.

Subject: [William Optics] First Light with New FLT 110 LiteLast night I was able to achieve first light with my new telescope, a
William Optics FLT 110. Mine is the new "Lite" version with the new
2.5" focuser, everything else is the same with the standard FLT
110's. Visual tests were encouraging, no false color and the star
rings looked good in and out of focus. Physically, this is a much
bigger scope than my W/O 80mm doublet! 30mm adds a lot of size and
bulk. It sure looks cool on the mount.
I was able to capture 3 new photos. 2 of the 3 are shown here. I've
more work to do on the third.
First is a shot of the Cone Nebula and Christmas Tree Cluster. 16
exposures of 6 minutes each. Combined and dark subtracted in Deep
Sky Stacker. Post processed in PixInsight LE and PhotoShop CS3. You
can see the photo here.

The second photo is of M44, the Bee Hive cluster. I shot this mainly
as a test of how flat the field is on my Canon camera. This on is
only 30 minutes of total exposure, 5 x 6 minutes. This is a full
size image without cropping. You can see some elongation of the
stars in the corners. I will need to get a field flattener someday.
I don't often photograph open clusters. I do like this shot, so
maybe more of these in the future. You can see the photo here:
