William Optics Redcat 51, ASI183MC-Pro with 2″ Ha narrowband filter by Svbony.
Mount: Skywatcher AZ-Gti in EQMOD, fw. downgrade to 3.20 from actual latest 3.26 to support PHD2 guiding in Astroberry server (Raspberry Pi4, 4gb).
After some attempts failed, according to some bugs reported for incompatibilities among astroberry>Kstars/PHD2 guiding, I downgrade my AZ-GTi to firmware 3.20, since then getting able to perform very quick calibration and autoguiding both in PHD2 and internal Kstars.
This is an integration of some Ha subframe taken at 300sec, Gain180, -15C with ASI183MC-Pro on WO Redcat 51 from home balcony, Bortle 6 urban sky.

A shooting star into NGC6910 and NGC6914 field.
From a single subframe taken by Canon EOS550d with CLS clip filter on William Optics Zenithstar 61, ISO400 600sec, while recording focused on NGC6910 available on sky from my balcony in the first part of the night.
To process this singular frame I made 3 copies and calibrated with dark/flat/BIAS once using normal BIAS integration, then using SUPERBIAS integration and calibration, thus to get 6 files to process with their drizzle data.
Postprod by Phtoshop and Lightroom.
