Olympus OMD E-M10 Mark II - Familiarisation
Overview
I have only used this camera for landscape photos previously in 'Auto' mode. Looking online at the large number of videos dealing with using DSLR cameras for astrophotography, the E-M10 seem to be adequate for that type of astrophotography activity.
NOTE: the E-M10 is not actually a DSLR camera - but is a mirror-less camera (See detail at the bottom of this page).
However - for astrophotography there needs to be attention given to settings which the 'Auto' mode cannot handle effectively. While 'Auto' mode works fine for everyday day-time photography, the low-light conditions of astrophotography do not provide enough input for 'Auto' to work satisfactorily- so venturing into 'Manual' mode is required with an accompanying learning curve..
Some experimentation with settings will need to done for various astrophotography scenarios...
Long single exposures without tracking (star trails)
Short multiple exposures without tracking (stacking)
Long single exposures with tracking (DSO)
Various lenses with different apertures and focal lengths
...but first a general familiarisation exercise is useful.

A DSLR (Digital Single-Lens Reflex) camera and a mirror-less camera are two distinct types of digital cameras.
DSLR Cameras: These cameras employ a mirror mechanism inside the camera body. When you press the shutter button, the mirror flips up to allow light to reach the image sensor. This mirror reflects the image from the camera's lens to an optical viewfinder, which provides a real-time optical view of the scene.
Mirror-less Cameras: As the name suggests, mirror-less cameras lack the mirror mechanism found in DSLRs. Instead, they rely solely on the image sensor to capture light. Mirror-less cameras use electronic viewfinders (EVF) or the rear LCD screen for composing and previewing images.
