Lovely Venus image NV, the gibbous phase is clearly visible and its nice and sharply focused.
I am completely unfamiliar with your camera, so I don't know whether you are operating at the optimum imaging scale or not with your scope. what's the pixel size for the camera?
I would guess probably not and a Barlow would bring you nearer. It will probably not however show on more detail with Venus, you need a UV filter (not cheap) to show the faint clouds. Its worth a try though because I am sure I have read in the past about people having some success with just a I/R filter.
I did try a few years back a Violet filter and a I/R filter to capture the clouds, but never managed any. It wasn't until I purchased my U/V filter I started to capture them.
