Attached a chronology of 220P from June 3 to June 19 of raw 30x10s stacked images taken by a SeeStar S50 with no processing done to them. The Moon moved very close to the comet on the mornings of June 6-10 which interfered with the images. The coma decreased in width while the dust tail increased in length from June 3-19, the dust tail was about 1/2 degree long on 6/19 but hard to see in this unprocessed image as the tail grew longer but fainter from June 3-19. |
