About the Observatory

Where Curiosity Meets the Cosmos

Washington Valley Observatory is an amateur astronomy collective on a mission to explore the cosmos through astrophotography and education. We specialize in capturing breathtaking images of deep-space objects using affordable, off-the-shelf telescopes and free, open-source software.

From helping a beginner find their first celestial object to teaming up with schools for STEM education, we are a place where anyone can connect with the stars. All of our imaging is done from light-polluted suburban skies in northern New Jersey, proving that remarkable results are possible anywhere.

Plan the whole night with the Observatory Toolkit

Homegrown tools for the imaging community. The FOV Viewer frames any target over real survey imagery: resolve it by name, compare rigs side by side, then copy the coordinates straight into ASIAir or NINA. The Sky Conditions Planner scrubs forecast cloud cover across a live map, hour by hour into the future, with seeing and transparency estimates, darkness windows and moonrise for any site. The Sampling Calculator matches a camera to a telescope and draws the star on your actual pixel grid. And the new Astro Calculators hub answers the rest: sub-exposure length for your sky, backfocus chains, focus zones, untracked limits, planetary Barlow picks, plus moon-interference and polar-alignment advisors.

Equipment & Imaging Stations

My Rigs

Five active imaging stations, each optimized for a specific use case, plus the retired rigs that earned their keep. Sensors now span the IMX585 platform and APS-C.

01
Primary 416mm Rig
Askar 65PHQ
416mm f/6.4 (flat-field astrograph)
  • ZWO ASI585MC Air (shared w/ RedCat 51)
  • ZWO EAF
  • Juwei-17 EQ Mount
The new workhorse. Flat-field optics and 416mm of reach for compact nebulae and galaxy fields alike.
02
Mobile 300mm Rig
Astro-Tech AT60EDP
300mm f/5 (Petzval quadruplet)
  • ZWO ASI2600MC Pro
  • ASIAir Plus
  • Juwei-17 EQ Mount
Wide-field master rig. The APS-C sensor drinks in huge swaths of sky at 300mm.
03
Mobile 250mm Rig
William Optics RedCat 51
250mm f/4.9
  • ZWO ASI585MC Air (shared w/ 65PHQ)
  • ASIAir (built-in)
  • Juwei-17 EQ Mount
Dark site kit for Stokes State Forest. Fast Petzval design, grab-and-go on the Juwei-17.
04
Ultralight Portable
Askar FMA180
180mm f/4.5 (w/ reducer) / 220mm f/5.5 (native)
  • ZWO ASI585MC Pro
  • ZWO ASI585 (non-Pro) for winter
  • ASIAir Mini
  • Sky-Watcher Star Adventurer 2i
The lightest rig. Second simultaneous mount at Stokes dark site. Tracking only, no goto.
05
Backup Mobile Rig
Apertura 60EDR
360mm f/6 (ED doublet)
  • ZWO ASI585MC Pro
  • Juwei-17 EQ Mount
  • ASIAir Mini
Backup and secondary mobile rig. Pairs with the Juwei-17 for grab-and-go when the primary mobile rigs are deployed.
06
Primary 350mm Rig
Retired
Astro-Tech AT72ED II
~344mm f/4.8 (w/ 0.8x reducer)
  • ZWO ASI585MC Pro
  • Juwei-17 EQ Mount
  • ASIAir Mini
The former go-to setup for fast-deployment wide-field deep sky from the driveway. Succeeded by the 65PHQ.
07
Galaxy Season
Retired
Astro-Tech AT102ED
~571mm f/5.6 (w/ 0.8x reducer)
  • ZWO ASI585MC Pro
  • ZWO AM5
  • Touptek guidecam
  • Raspberry Pi + CCDCiel
Indoor window station for galaxy season. RPi-driven due to Gemini focuser + Touptek incompatibility with ASIAir.
