Couple of Clusters NGC3532 & NGC 3766

Since there was a bit of Moon about did these two clusters to see how well the mount was tracking.
Details
Canon 5DH fridge at -5.0C, Meade SN10 with Paracorr PLU 1106 so FL is 1152 at f/4.6, Hutech LPR filter.
Exposures 10x(7s, 15s, 30s ,1m ,2m ) at 800 ISO. Used the new version of EasyHDR. The input stacked exposures were adjusted for levels in Photo Shop for colour balance etc before loading into EasyHDR. I used the controls in EasyHDR so there was minimal post adjustment in Photo Shop. This means when any adjustment is made you have the data from all the input images to affect the final tone mapped output. I am still figuring out what works best.

NGC3532 1.5MB

NGC3766 1.5MB

These two images are slightly cropped and their FOV is 1.6x1.2 degrees. I have also put up a map showing where these two clusters are situated.
