This dataset captures the Veil Nebula (NGC 6960), a supernova remnant in Cygnus, through 50 frames taken with an Askar E1 Dual Band 3nm Hα+OIII filter on 2025-10-06. The total integration time reaches approximately 4.2 hours at 300 seconds per exposure. Imaging was performed using a Nikon 240mm f/5.6 lens paired with a ZWO ASI2600MC Air camera on an AM5N mount, a combination well-suited for wide-field nebula work at this focal length.
The dual-band narrowband filter isolates hydrogen-alpha and oxygen-III emission lines, revealing the delicate filamentary structure characteristic of this ancient stellar explosion. Available under CC BY-NC 4.0 licensing for roughly $7.90 as a one-time purchase, the data permits copying, modification and redistribution for non-commercial purposes, making it accessible for educational projects, processing practice or portfolio development.
