LDN 673 is a dark nebula captured here through 14.4 hours of narrowband and broadband imaging between August and October 2024. The dataset comprises 431 total frames: 211 luminance exposures at 120 seconds each, plus 74 blue, 73 green, and 73 red frames through Antlia 1.25-inch filters, all at matching two-minute exposures. Data were acquired with a TS-130 APO refractor and ASI294MM Pro monochrome camera on an AM5 mount, providing high-resolution monochrome channels suitable for LRGB processing or scientific analysis of this obscuring cloud in Aquila.
The files are offered as a one-time purchase at approximately $19.90 under a CC BY-NC 4.0 license, permitting copying, modification, and non-commercial redistribution. Calibrated sub-exposures allow custom integration strategies, noise profiling, and experimentation with different combination weights across the four filter bands.
