Observing equipment: ETX-70AT, Scopetronix Solar filter, 40mm eyepiece, Scopetronix Digi-T adapter
Camera: Canon MV650 DV Camcorder, Registax2 image processing.
Presentation: Most recent images are rotated to match the view as presented on the SOHO satellite images

Size comparison: In the some of the following frames I've included markers showing the approximate size comparison to Jupiter (orange disc) and Earth (blue disc).

1/500 various AE setting adjustments tried but found the best was AE 0. The remarkable circular group (488) had appeared about 12 hours before these images.

After a frustrating day with no breaks in the cloud the sun eventually broke through but by then was only about 30 deg above the horizon, seeing was poor through the smoke of next doors bonfire!

These images are each about 400 frame stacks taken with the MV650i/ETX-70 combination. The closeup of Group 375 was taken with the Camcorder on maximum zoom, unfortunately the focus was not spot on which the processing can never compensate for. As a comparison the second (coloured) picture from shows the groups detail.

Tried to capture an ISS solar transit but clouds intervened at the critical moment. Had to settle for this full disk image - a stack of approx 400 frames captured from digital video.
