Nirmal Jangid

Backyard astrophotographer based in Mecklenburg, Germany. Most clear nights end up under either a Bortle 5 sky over the back garden or a Bortle 3 sky at the edge of Plau am See, depending on the moon, the weather, and how far the imaging laptop is willing to travel.

Most of the work on this site is built around two cameras and one rig. A Sky-Watcher Explorer 200P Newtonian sits on a Sky-Watcher EQ5 Pro SynScan mount, fitted with a TS-Optics coma corrector and a Pegasus Astro Gemini EAF for per-filter autofocus. The 50/90 mm finder doubles as a guide scope with a ToupTek 327C feeding PHD2.

The choice of camera depends on the target. Faint galaxies and HII regions go through the cooled mono ToupTek ATR533M behind a motorised filter wheel — L, R, G, B and 1.25″ Hα / OIII / SII narrowband filters, plus a 2″ Hα + OIII dual-band kept aside for fast OSC sessions. Wide broadband captures and quick session-by-session imaging use the ToupTek 183CA one-shot colour.

Acquisition is split between two laptops: N.I.N.A. on a Windows imaging laptop for most sessions, with a Linux KStars/Ekos stack on a Raspberry Pi 5 at the mount for quieter nights. Stacking and linear post happen in Siril; non-linear stretching and final cosmetic work in GIMP.

The dark site that does most of the heavy lifting is a small village called Klebe at the edge of Plau am See, in the Mecklenburg lake country — quiet enough that the Milky Way is naked-eye obvious and dark enough that the bright Bortle 5 backyard becomes the rough-cut location and Plau am See becomes the finishing site.

Long term, the goal is a backyard roll-off roof observatory — a small 2.4 × 2.4 m structure for the EQ5, the imaging laptop and the Pi 5 to stay permanently set up. Until then, every clear night is still set-up and tear-down.
