Saturn & moons imaged in LRGB at f10 through a C8 with DMK41au02 CCD for the luminance channel and Skyris618C CCD for the color data.

Saturn imaged in LRGB at f33 through a C8 with DMK21au618 CCD for the luminance channel and Skyris618C CCD for the color data.

The Small Magellanic Cloud (NGC 292) visible from the southern hemisphere, a companion/satellite galaxy of our Milkyway 203,000LY away. Exposed at 300mm focal length through an Sigma 150mm f2.8 prime lens with a 2X Teleconverter, QHY268M camera, guided with a 80mm refractor at 500mm FL and tracked on a hypertuned CGEM mount. This image was an experiment where I exposed the luminance channel again at 300mm focal length but used the LRGB, H-Alpha and OIII color data exposed with the SMC at 150mm focal length. The 2X converter does distort the image a bit, enough distortion where it's better to crop in the wider image rather than expose with the extra glass. Total exposure time was 20 hours and 1 minute.

The Small Magellanic Cloud (NGC 292) visible from the southern hemisphere, a companion/satellite galaxy of our Milkyway 203,000LY away. Exposed in LRGB with H-Alpha and OIII color at 150mm focal length through an Sigma 150mm f2.8 prime lens, QHY268M camera, guided with a 80mm refractor at 500mm FL and tracked on a hypertuned CGEM mount. The 15% narrowband data screened over the LRGB image emphasises the nebulosity within the satellite galaxy. Total exposure time was 19 hours and 4 minutes.

This image of a part of the Milky Way/Sagittarius region was imaged with a QHY268M and a Sigma 80-400mm EX zoom telephoto lens at 80mm focal length on the nights between 25th June and the morning of 9th July 2022. Sagittarius is a large constellation located south of the ecliptic, FOV near toward the center of the Milky Way galaxy. This constellation is in a region of the Milky Way which is rich in gas and dust as well as various nebulae and objects through out. Objects such as the Omega, Trifid and Lagoon nebulae... full list of objects detected in Astrometry.net listed below. The total integration time for this image was 14 hours and 52 minutes of subs, 54 subs each of 90 and 180 second for Luminance, and 100 x 60 second subs for the red channel, 71 x 120 second subs for the green channel and 64 x 180 second subs for the blue channel for the broadband data and 43 x 300 second H-Alpha subs to emphasize the Hydrogen Alpha signal in the frame.
