Description

I am processing some early data from 2014, when I was starting to use my new C8EHD.

I was constrained to 2 mn sub exposures maximum due to differential flexure with my parrallel guiding system.

I eventually realized that most of the flexure originated from the Orion XY Guide Star Finder !!!!

This specific picture is teh result of the selection of 15 out of 21 exposures (clouds and bad guiding).

Pre-processing done in Pixinsight :
