Description

First light for the prize camera Player One Neptune-M (IMX178 sensor) under good transparency but turbulent air as one can see when zooming in to the limb. The larger sensor provides a wider field which helps minimize panel count for a full disk lunar mosaic, in turn the fastest frame rate at maximum ROI is 60fps which is about three times slower than the ASI290MM (IMX290 sensor), which makes sense as the IMX178 is three times larger than the IMX290 by area. This also reflects in stacking time in AS!3. Physical limitations invite compromises. The smaller pixels of the IMX178, 2.4µm, entail a slightly better resolution than the IMX290 with 2.9µm pixels but seeing needs to be favorable to benefit from the difference. Smaller pixels collect less light in that the IMX178 demands slightly longer exposure times. Full ROI images are about 3000 x 2000 pixels large in that drizzle in AS!3 is not necessary for obtaining images in excess of HD resolution. The Neptune-M should be a formidable autoguide camera owing to its small pixels and wide field.

Mosaic of 7 panels, 8ms, gain 200, 60fps, 600x, mono8, 10-bit ADC, no drizzle, native focal length. Note the favorable eastern and northern libration of about 7 degrees.

Images in the Revision are taken with a 2x tubeless barlow (effective x1.4).
