Description

With almost 3000mm of focal length, flat field, relatively small FOV and 0.55"/PX of resolution this is a pure unadulterated up close and personal setup for galaxies, planetary nebula and smaller sections of larger nebula. Most of us lack the scope for this sort of imaging, so it will allow many members to image in a way they normally cannot from home with their own equipment.

The longest sub lengths we will do on this pier in the future are 600s, for those that still prefer longer subs
