M27 Dumbbell Nebula - Askar 131f First Light
First light test with the new Askar 131F telescope! Captured M27 over two nights under a \~77% Moon from my backyard in Southern Italy.
The 1000mm focal length frames the core nebular details nicely, and the 3nm dual-band filter did an incredible job keeping the lunar glow and light pollution at bay.
# Equipment & Acquisition:
* **Telescope:** Askar 131F Triplet APO
* **Mount:** ZWO AM5 + ZWO TC-40 Tripod (+ Extension Pier)
* **Main Camera:** ZWO ASI533MC PRO
* **Filter:** Optolong L-Ultimate (3nm Dual-Band Ha/OIII)
* **Focuser:** ZWO EAF
* **Guiding & Control:** ZWO ASIAIR plus/ ZWO120mm Mini
# Exposures & Location:
* **Lights:** 60 x 300s + 130 x 180s (Total Integration: 11.5 hours)
* **Gain:** 100 | Temp: -10°C
* **Bortle:** Class 4
* **Location:** Basilicata, Italy
# Processing in Siril:
* Naztronomy OSC-PP for calibration & stacking
* BlurXTerminator / NoiseXTerminator
* StarXTerminator
* Generalized Hyperbolic Stretch (GHS) on non-linear data
* Curve adjustments for Ha/OIII contrast enhancement & color balance (veraLux Curves and HDR Multiscale)
Feedback and critiques are always welcome!
