For the Veil Nebula I used an Askar FMA180 scope because it's a very large celestial object, for the others I use a WO ZS61 mkii.
Just to clarify, these are both standard telescopes although the Askar can be used for terrestrial photography, the big difference is the camera. It's a fully astrophotography camera, a ZWO asi533mc Pro.ah ok.. so lenses for a camera.. rather than a telescope that you attach a camera to.. good to know..
