No.4 - Getting Started in EAA, Part III
I n the last issue , we discussed what sort of cameras and what types of software can be used to do EAA. For anyone coming from a visual astronomy background, cameras and EAA software can be unfamiliar territory. However, the other key pieces of equipment needed for EAA - optics (telescopes or lenses) and mounts - are items that many visual astronomers already use. One of the most common questions that comes up is, "Can I use my existing scope and mount to do EAA?" As is the case for many things in astronomy, the answer is .... it depends. Telescopes The good news is that many scopes used for visual astronomy can be used for EAA. As was mentioned in the last issue of this blog, one important consideration when looking at various scope and camera combinations is the resulting field of view: A long focal length scope may be usable for EAA with a large sensor camera if the FOV is not too small. Conversely, a short focal length scope may yield a wide field of view, but on...
