Description

Had an 88 degree overpass of the ISS - but its an iterative process to get the exposure right.

This is my 3rd attempt - but I am still over-exposed.

1000mm focal length, 0.5 ms exposure and 250 Gain, Luminance filter on the ASI1600mm Pro (-20C). It seems I forgot just how sensitive a mono-cam is.

Next attempt I'll drop the Gain to around 150 and the exposure from 0.5ms to around 0.3ms, and see if I can pick up a 2X Televue Powermate to double the number of pixels of the CMOS chip that capture the ISS.
