Optimum Subexposure Calculator

Exposure time is one of the key parameters that an astroimager has to chose. Years ago the most accepted rule was «expose as long as you can», that means, the longer that your autoguiding system, or your light pollution allowed. Exposing as long as you can gives a good amount of signal on every subexposure, […]

RGB Stars from Narroband Data

This article explains a practical approach to one of the difficulties of narrowband images: the colors of the stars. The usual combinations (SHO, HOO) produce uncalibrated colors for the stars. This issue is usually solved by shooting also in RGB to replace the narrowband, but this leads to 2 additional issues: The investment in additional […]

TELESCOPE FLOCKING

This article explains how I flocked some inner parts of my telescope that I supected that could produce internal reflections. The goal of this implementation is mainly to improve the flat field calibration of the subexposures. It is an economic modification and the materials are easy to find, but please note that the task can […]
