M8 Lagoon Nebula

M8 Lagoon Nebula

My tracking mount is not very accurate and this shows up as trailed stars in longer exposures, particularly when aimed close to the equator. Recently I have learned how to use my ASI178MC camera as a guide camera so I can take longer exposures using the Canon camera on the main scope. I was very happy with the results on this target and other nebulae in Cygnus. I didn't have to throw away any frames because of trailing!br/ This nebula is easy to find in the dark skies of North Frontenac where it is a naked eye fuzzy patch just above the spout of the Teapot (Sagittarius). The small cluster at the lower left in the picture is globular cluster NGC 6544 also called the Starfish Cluster.br/ Date: 2022-08-27br/ Location: Ardoch, North Frontenac, ONbr/ Equipment: Z73 + M100, guidedbr/ Settings: 120s exposures at ISO1600, stack of 20 lights, 4 darks, 20 flats and 20 flat darks in DeepSkyStackerbr/ Processing: PixInsight for background neutralization, colour calibration, stretching, noise reduction and star erosion.
