IC1396 SHO-RGB Mosaic - Sep-Nov 2023
IC 1396 is a star-forming region of gas and dust in the constellation Cepheus. Spanning ~2.5 degrees in the sky, it appears to us almost 5x the diameter of the Moon. Its nebulosity can be faintly seen visually through a telescope under dark skies, but photographically, it is dramatic.
Due to the nebula's large size, this image is a 6-panel mosaic captured through both narrowband (SII, Ha, OIII) and color (R, G, B) filters over multiple nights in September and November of 2023. Most data was collected under dark skies near Goldendale, WA, with SII and some RGB data captured from Seattle, WA.
Telescope: Tele Vue 76mm refractor with 0.8x reducer
Camera: QSI 683wsg
Mount: iOption iEQ45 Pro
Narrowband Filters: 5nm Ha (Astrodon), 3nm OIII (Astrodon), 8nm SII (Baader)
Integration (Per-Panel): 10x5min Ha, 5x5min OIII, 9x5min SII, 5x30sec RGB
Processing: PixInsight 1.8, with minor final adjustments in PaintShop Pro
