[EP.50] Image Processing of TRIANGULUM GALAXY (M33) by SiriL and GIMP: Blend Broadband and Dual Data

In this tutorial video, I combined approximately 10 hours of broadband data and 20 hours of narrowband data using SiriL and GIMP. Background extraction was performed separately on each day's observation before manually stacking the data in SiriL to produce both broadband and narrowband images. I then stretched both images and split them into RGB channels, resulting in six separate images. Using GIMP, I blended the narrowband red and green channels with their respective broadband counterparts. The final image was recomposed in SiriL. - - Imaging Details - - - Deep sky objects: M33 / NGC 598 Date: August 4, 2024 - December 02, 2024 (18 nights) Location: Bunkyo-ku, Tokyo (Bortle Class 9) Imaging Camera: Vanis Vespera Mark I Filter: Dual Band Filter (501.6 nm, 654.9 nm, 12 nm) Integration: 9 h 18 mins (Broad) + 19 h 58 mins 10 secs (Dual) Image processing device and software: - - Vespera Observation Station: Vespera is your new observation station, the perfect combination of telescope and camera.
