Sunspot AR652 was created by daveg
Here's Venus as it appeared at 11:30 in the morning. I offset from the Sun after taking the sunspot image below to find it.

In general it's the CG11 at f/5 (Giant Easy Guider lens in the forward position) The camera is set at 1/1000sec and gain at about 20%. I use the cam in RAW mode but I think that the most important thing is to image early/late enough. Try and balance between the Sun being high enough and befoe it gets too hot during the day.

Hope this helps
