It came out sunny this afternoon, so had my tea break and tried first my DMK21, nice lot of surface detail and then the modified MS Lifecam with and without IR filter. There was a difference with the IR filter, slight focus difference, but it didn't really help with bringing out any more detail.

I tried fiddling with the gain and exposure settings as well as the colour balance and saturation, all gave no improvement. Ended up coming back in and ordered a DMK41 from FLO.

Now to see about removing some of the eyepiece holder to get the DMK in focus without a barlow.
