M42 + IC434
While the skies haven't been ideal, I gathered all my September equestrian Orions.
Imaging was done:
In 2023 with an Askar ACL200 and ZWO ASI 2600MC DUO + AM5 in Khosta (Sochi) using an Antlia ALP-T Ha + OIII 5nm filter, and at the Caucasus Mountain Observatory without additional filters with 10-minute exposures.
In 2025 with a Sharpstar 50EDPH + 0.84x reducer and ZWO ASI 2600Air + a homemade 2×11 harmonic drive in Kashtany (Sochi) with the remaining 3 filters.
