I got an alert that the ISS would cross the disk of the sun at my place this morning, so despite the clouds I prepared the obs and had everything ticking over for the pass at 10:56:18.25s. About T-15 minutes I got a break in the clouds - enough to do a rough focus anyway, then at 10:55 the clouds cleared...
No time for a final focus... start the camera and cross fingers...
About 10:55:40 the clouds start to roll across the FOV again, but they held off enough for me to capture 13 frames with the ISS in front of the disc of the sun!
My first successful crossing capture!
I've uploaded the
10.1M animation of the pass here:

If weather permits next time I get a chance at this, I'd like to capture a full disc mosaic, then capture the ISS pass at a faster shutter speed, stack and mask to reveal the captured ISS over th detailed disc. I captured at 1/60s this time which blurs the ISS... definitely need a faster shutter
.
BTW the animation is about 50% slow, as I captured at 15FPS but the animation is at 10FPS. You may also notice that the camera dropped 3 frames during the crossing...
