Description

Luminance exploration. Composite of data taken on 2 cameras, 2 filter sets, with 2 different automation set-ups. Why? Glutton for punishment. Primarily a focus and guiding test.

Acquisition dates:

May 7, 8, 10, 12, 13, 14, 24.

Acquisition spread across 2 different STX-16803 (due to mechanical failure), and 2 different filter sets (Baader initally, but switched to Astrodon). Over this same timeframe the system was converted from CCDAP to ACP Expert, multiple T-Point model (>= 300 point with the final one being nearly 500...more is better?!?!?...pointing is good to 12 arcseconds), AO-X (only on a subset of frames) keeps guide errors to <= 0.3 pixels. Unguided imaging tests good to 10 minutes on PME with Protrack and PEC engaged imaging at 3300mm FL.
