DSO Imaging

Here is a high-level view of the process with specific terms & stages explained in more detail later.

Hardware

This section assumes you will be using:

  • Computer
  • GOTO mount
  • Telescope
  • Guider (Already Focused)
  • OSC Camera (Astro or DSLR)
  • Focuser
  • Dew Heater

Image Control Software with the following capabilities:

  • Integration with Planetarium Software
  • Scope Control
  • Auto Focusing
  • Plate Solving
  • PHD2 guiding

The aim is to take a defined number of exposures (Lights) over a time (Total Integration Time) plus Calibration frames of a chosen target. The Image Control software will control all of these elements.

  • Choose an object in the Planetarium software.
  • Unpark scope & slew to target.
  • If your scope is Polar Aligned and you are starting from a known position (even roughly) it is not necessary to do a star alignment if you are using Plate Solving.
  • Auto Focus
  • Plate Solve Target
  • Frame & rotate the target
  • Define imaging sequence:
  • Number of frames; exposure, gain, offset
  • Start Imaging.

Take Calibration Frames:

  • Darks
  • Lights
  • Dark Lights OR Bias

The actual Software operation will vary for each different control system. Here is video of an example run through for NINA:
