Many thanks. The clouds came over here at about 5:30pm, but the sun was in the trees by then anyway. I think I have around 70 exposures! I may be able to do a multiple exposure showing the progress of Mercury across the sun, but that will take a while on an alt-azimuth mount! In the meantime I want to write up the log otherwise it will get left. I look forward to seeing your results.
I use an 11" Celestron SCT (CPC 1100) on an equatorial wedge, housed in a 2.2m Pulsar observatory. I use a ZWO ASI1600MC and Canon 500D for imaging.

I managed to put together 5 exposures. This is Mercury at 1200, 1300, 1400, 1500 & 1600 UT
It was harder than I thought it would be. Each image had to be rotated 15 degrees more than the previous. The sunspot also moved during that time. The position on the image is that at 1200. I'm sure it isn't perfect, but I can have another go later.

Given time I could add the half hours too!

The weather is preverse. All my American friends were clouded out on the 9th.
Today we are clouded out, and it is raining. On this occasion the weather was kind to us.
