# Telescope Night Kit

From scope + eyepiece specs to what you can see and how to photograph it.

Status: **observed**Lifecycle: **verified-workflow-definition**

## Goal

From scope + eyepiece specs to what you can see and how to photograph it.

**[Magnitude ↔ Flux Ratio](<https://guthlabs.ai/docs/instruments/magnitude-flux-ratio/>)**

## Handoffs and cross-checks

Same aperture/focal inputs fan out to all; FOV must contain target angular size; NPF uses the imaging focal length.

## PointGuard stance

Confirm target fits FOV and exceeds resolving limit before recommending an exposure plan.
