Details:
C/2021 T4 (Lemmon) passing by a dark nebula in Lupus (20 cm telescope Hakos H8 2.8, 2x180 sec. RGB each+3x180 sec. L) and C/2023 E1 (ATLAS) near a red emission nebula in Cepheus (40 cm Dream Astrograph Utah, 5x60 sec. RGB each+7x60 sec. L, separately for both the comet and background). Both comets were around magnitude 9-10 at the time of imaging, C/2021 T4 (Lemmon) being only a week after its perihelion. Data taken remotely through the system of Skygems Observatory Network from Namibia and Utah and mainly processed with Siril. Comet isolating was done in StarNet2, compositing comet-only and background images in StarStax, finishing touch (contrast, crop) in IrfanView.
