Polar Scope Align vs Photographers Light Table

Polar Scope Align is a free, ad-supported polar alignment app for iPhone and iPad. It calculates the position of Polaris or σ Octantis in your polar scope reticle for your location, date and time, helping you get a quick and accurate polar alignment with an equatorial mount. POLAR SCOPE ALIGNMENT • Accurate Polaris and Sigma Octantis position for your date and location • Atmospheric refraction correction for better accuracy, especially at lower latitudes - readings may differ slightly from simpler apps that skip this correction, but will agree with precise sources (USNO, scientific software) • Automatic time and location • Manual location support • Reticle centering-error measurement and correction • Zero-position help for common Celestron / Sky-Watcher / Orion style reticles • Full red night-mode interface SUPPORTED RETICLES Polar Scope Align supports 35+ polar scope and finder reticle types, including: iOptron, Astro-Physics RAPAS & PASILL, Takahashi (EM-10/11/200/400/500, NJP, PM-1, P2-Z), Sky-Watcher / Orion (including EQ6/AZ-EQ and Star Adventurer), Celestron, Meade, EXOS2, Bresser, Vixen (Atlux/SX/SXD/SXP/AXD/GP/GP-DX, Polarie), Astrotrac, Losmandy, Kenko, Avalon, Konus, Telrad, Rigel QuikFinder, and several older polar finders (Tuthill, Explore Scientific, Meade 9x60, Vixen Polaris, Celestron 7x50, Carton Optical). OBSERVING TOOLS The free version also includes: • Moon phase • Messier, Caldwell and bright-star database • DSS image downloads for included database objects • Saved, editable and printable DSO lists • 8 astronomy calculators for observing and imaging • Sample Pro tools available from Settings, including aurora forecast • iOptron WiFi Connect - report mount status, set mount Time/Date/Location LOOKING FOR ALIGNMENT WITHOUT A POLAR SCOPE? Polar Scope Align Pro adds the advanced tools many users search for: • Daytime / No Polar Scope Alignment • Camera Azimuth Calibration using the Sun, Moon, planets or bright stars • Laser / Hop Align for night alignment when Polaris is blocked • Push To / manual GoTo for non-GoTo telescopes • Live sky maps for Daytime Alignment, Laser / Hop Align, Push To and Hop To • Full 22,000+ object DSO database • Xasteria astro weather, aurora, satellite passes and widgets • 30+ calculators • Bubble level, compass and iOptron WiFi mount control • Apple Watch companion app • No ads If you only need accurate polar-scope alignment, this free version is a capable tool.

Photographers Light Table turns your iPhone or iPad into a clean, evenly lit surface for viewing film negatives and slides, checking prints, and shooting astrophotography calibration flats. Precise, portable, and ready whenever you are. VIEW FILM AND SLIDES Backlight negatives, transparencies, and contact sheets for inspection, DSLR scanning, or digitising — no bulky light box required. PRECISE LIGHT CONTROL Dial in brightness and colour temperature with full-width sliders and live readouts, from warm tungsten to daylight. Pick any custom colour, and keep the ones you use most one tap away. GRID OVERLAY Turn on an adjustable grid for alignment, framing, and repeatable setups. REMOTE CONTROL Adjust your light table from another device without touching it — handy when it's under a camera or telescope. Use any web browser on your WiFi, or a nearby iPhone or iPad directly, with no shared network needed. Group several tables and drive them together, or focus any single one. An optional PIN keeps your table private. SAVED SCENES Store your setups by name and recall them instantly. Apply, rename, and export scenes right from the remote, and back them up or move them between devices. LIGHT EFFECTS Gentle, photosensitivity-safe effects — Breathe, Colour Cycle, and Candle — plus your own programmable colour sequences. ASTROPHOTOGRAPHY FLATS Produce an even, stable illuminated field for flat frames, with fine brightness control and steady output. Photographers Light Table is free and supported by ads. A one-time Premium purchase removes them.
