20140526 No tracking solar imaging

The Sun is still in a bad place from inside my room, and it is impossible to use my Mark-X for tracking.

1436 (GMT+8), at prime focus, no tracking and thus shifting and expand during stacking:-

 

1438 (GMT+8), with 2x barlows, no tracking and again shifting and expanding during stacking, the zip-zap line on the bottom is the artifact:-

I will try to keep on imaging even no tracking is possible.
