Description

My time was limited by a late start and another member waiting for the 14" scope, so I went after the Owl on the premise that I could just add more frames to an earlier session that was cut short. These frames turned out well enough that I didn't bother adding the other data, though.

It was also a chance to try another approach to flats. I had been using a light panel that another member made for us, however that light has a strong green color that rendered my calibrations frames unusable. This time I just put a big white sheet of foamcore against the dome and illuminated it with a wide flashlight. Technically it worked, but it also added a lot of noise to my frames, and I'm not sure why.
