+The camera setup can be mounted a wide variety of ways,
+from just setting the camera somewhere (worst option), to a heavy duty
+pier with tracking mount (best option).
+
+At present, most prototype optical ground stations are using static mounts
+on tripods.
+
+Tripod and similar options include:
+
+\begin{mdframed}[backgroundcolor=blue!10,linecolor=blue!30]
+\begin{description}
+	\item [No mount] --- Quick and dirty, just hang the camera out somewhere sitting on something.
+	\item [Small tripod] --- There are small desk tripods than can be used with lighter
+         setups, such as used with a Raspberry Pi PiCamera.
+	\item [Photography Tripod] --- Using a common camera tripod, of which there is a wide
+         variety, from light to heavy.
+	\item [Telescope Tripod] --- Similar to photography tripods, but typically heavier weight.
+	\item [Telescope Portable Pier] --- Similar to a telescope tripod, but much heavier, typically
+         with a larger center pier post. Still movable, and folds up similar to a photography tripod.

+\section{Mounts}
+\label{sec:hardware-mounts}
+\index{mount}\index{track}
+For mounts, there are two main types: tracking or static.
+By the latter ``static'' mounts, it is meant that the
+camera, the tripod, and the mount all stay motionless.
+This is what you would get using a camera with a common photography
+tripod and a simple mounting plate.
+
+Static mounting options include:
+
+\begin{mdframed}[backgroundcolor=blue!10,linecolor=blue!30]
+\begin{description}
+	\item [Camera plate] --- Commonly used on cameras and readily available for mounting
+         cameras to tripods.
+	\item [Enclosure plate] --- A flat plate with holes drilled in it to mount the camera
+         inside an enclosure.
+	\item [``Security'' camera enclosure mount] --- Various mounts exist to mount
+         security cameras to posts, walls, etc.
+\end{description}

+Tracking mounts aren't widely used, but there is support for them in
+\texttt{stvid} when acquiring data.
+The tracking needs to be set up independently of \texttt{stvid}.
+At present, I use Kstars with Ekos to control a Sky-Watcher tracking
+mount.
+\index{KStars}\index{Ekos}\index{Sky-Watcher}\index{stvid}\index{track}
+
+For tracking, there a few different ways to track:
+
+\begin{mdframed}[backgroundcolor=blue!10,linecolor=blue!30]
+\begin{description}
+	\item [Static] --- No tracking, just point at one place in the sky.
+         Generates star trails.
+         Generates satellite trails.
+	\item [Sidereal tracking] --- Tracks stars.
+         Generates stars as points.
+         Generates satellite trails.
+	\item [Satellite tracking] --- Tracks satellites.
+         Generates stars as tracks.
+         Generates satellites as points or potentially larger images
+         of the satellite structure.
+\end{description}
+\end{mdframed}
+
+\subsection{Sidereal Tracking Mounts}
+Sidereal tracking (``telescope tracking'') is what \gls{COTS} tracking ``GOTO''
+\glspl{telescope} from Celestron or Sky-Watcher do, for example. They tracks
+the stars, countering the rotation of the Earth to keep the same view
+of the sky in the camera's \gls{FOV}. Stars remain as points, even after multi-minute
+or multi-hour imaging. This is what is used for ``pretty'' pictures
+of stars, nebula, galaxies, etc. 
+This is the most common tracking set up, as it has been widely used in
+astronomy communities for decades.
+
+
+Within sidereal tracking mounts, there are yet more options:
+
+
+\begin{mdframed}[backgroundcolor=blue!10,linecolor=blue!30]
+\begin{description}
+	\item [Fork] --- Fork mount.
+	\item [EQ fork] --- Fork on EQ mount.
+	\item [German EQ] --- Most common EQ mount.
+	\item [More] --- Endless variety of available telescope mounts.
+\end{description}

+\index{mount}\index{track}
+ 
+Also related to sidereal tracking is lunar and planetary
+tracking, but for our uses all three will be included under sidereal tracking.
+
+To use a sidereal tracking mount for imaging satellites, the camera
+must ``leap frog'' the satellite.
+At present, my practice is to use a sidereal mount, point at a location with Kstars,
+start stvid. Then stop stvid, move to new location using Kstars,
+start stvid.

+
+\subsection{Satellite Tracking Mounts}
+\index{track}\index{mount}
+Of the options between a static mount (no tracking), sidereal tracking,
+and satellite tracking, the latter is by far the least common.
+In this case, the tracking mount is tracking the satellite itself.
+This is much more complex than tracking stars, which it builds upon.
+It requires, such as:
+
+\begin{mdframed}[backgroundcolor=blue!10,linecolor=blue!30]
+\begin{description}
+	\item [Time] --- Accurate time, such as from \gls{GNSS}.
+	\item [Location] --- Accurate location, also available from \gls{GNSS}.
+	\item [TLE] --- Need to know the \glspl{satellite}' orbit (accurately!).
+        \item [Variable speed tracking] --- \Glspl{satellite} are moving at different
+         speeds above, the mount needs to be capable of that.
+	\item [Human guided] --- Some skilled amateurs track by hand.
+	\item [Alignment] --- On top of all the gear and software needed,
+         the equipment needs to be accurately aligned.
+\end{description}
+\end{mdframed}
+\index{GNSS}\index{TLE}
+
+Most tracking equipment for \glspl{telescope},
+cameras, and antennas usually has just a few speeds, such as a slewing speed
+and a sidereal star tracking speed. Sometimes there will be a few steps
+of these speeds (e.g. slew speeds from 1-9), but not the finely tuned tracking
+speeds needed to track a satellite. Oftentimes the telescope tracking maximum
+speed will be too slow for satellite tracks.
+
+Variable speed tracking (XXX phrase?) is needed for tracking satellites if
+the goal is to keep the satellite in the (near) center of the image frame
+and leave star trails. The speed the mount moves needs to be calculated
+based upon a recent orbit calcuation, such as from a \gls{TLE}.
+
+There are highly skilled amateur astronomers that have captured detailed
+pictures of artificial satellites, such as the ISS and astronauts doing
+space walks, using hand guided telescopes with low cost \gls{CCD} imagers.
+\index{CCD}\index{ISS}
+% XXX ref
+
+There are few options for satellite tracking mounts.
+Some new iOptron telescope mount firmware supports tracking
+satellites. This has been largely untested so far, but at present
+is likely the best option, if a satellite tracking mount is wanted.
