Widefield yet to come, here is comet 13P/Olbers taken on June 30 Local Time as it rounds the sun. I've skipped ahead to process last nights imaging data. Three past days have yet to be fully processed and what I've seen each day showed significant structural changes in both closeup and wider-field setups. Stay tuned.
