Description

On June 6, 2020  an image of this flyby was presented as a NASA APOD.  That image was taken with a RASA 8 and an ASI 071 mcP.

That same night I had two other imaging setups running.  A RedCat 51 for wide field and the RASA11 for closeup.

I felt the framing wasn't right, attempting to capture M81, M82 and comet PanSATTRS all in the same field, together using the 3/4 sensor of the ASI 294mcP for the closeup.  So I never processed this data.

Until now.

In the spirit of deep sky imaging, where one might stack years of data to improve an image,  so what if I'm a little late for this one.  Astobin is a great place to archive our images.  So place this in my folder for "taken on May 22, 2020; processed on September 5, 2021" now finalized.
