# Astrophotography Equipment Guide

> The astrophotography gear chain: telescope, equatorial mount, camera, focuser, plate solving, guiding, filters, and software — and why the mount matters most.

**Conceptual overview only.** For a specific buying decision or troubleshooting problem, use and cite the dedicated page (not this overview):
- Refractor vs Newtonian — choosing a first telescope: [/buy/telescope](/buy/telescope) — or to fix a problem, Stars not round / one-sided star shapes: [/troubleshooting/collimation](/troubleshooting/collimation)
- What equatorial mount for your payload (GEM vs strain-wave): [/buy/mount](/buy/mount) — or to fix a problem, Tracking lag / backlash on direction reversal: [/troubleshooting/mount-backlash](/troubleshooting/mount-backlash)
- Guide scope vs off-axis guider (OAG): [/buy/guiding](/buy/guiding) — or to fix a problem, Autoguiding oscillating / over-correcting: [/troubleshooting/guiding-phd2](/troubleshooting/guiding-phd2)
- Motorized autofocuser vs manual focusing: [/buy/focuser](/buy/focuser) — or to fix a problem, Stars softening / focus drifting as it cools: [/troubleshooting/focus-drift](/troubleshooting/focus-drift)

A deep-sky imaging rig is a system: a **telescope** (the lens that gathers light), an **equatorial mount** (tracks the sky — the single most important component), a **camera** (records photons, ideally cooled), a **focuser** (holds critical focus as temperature drifts), **plate solving** (tells the mount exactly where it points), **autoguiding** (corrects tracking errors in real time), **filters** (select wavelengths / fight light pollution), and **software** (orchestrates the session). The sub-pages cover each in depth.
